The aims of this study were to examine the effect of pollen substitute (PS) and nectar substitute (NS) on the productivity of Apis cerana colonies and the quality of honey according to Indonesian National Standard for honey. Provision of PS and NS serves as a substitute for natural pollen and nectar. Pollen Substitute was prepared from wet biomass of yeast Saccharomyces cerevisiae and NS from pineapple syrup. The feed were given to the colony by mixing 2 g of PS and 50 ml of NS. Ten honeybee colonies were used in this study, five colonies were used as feeding trials and five colonies as control, and they were allowed to forage on flowers. Pollen substitute and nectar substitute were provided to the colonies every day for two periods (total 12 weeks, six weeks per period). Honey quality analysis was performed after six weeks. The results of provision of PS and NS in two periods to the colonies showed the greater than the control in their increasing of honeycomb circumference and the number of honeycombs. However, the results of the T test showed that the provision of PS and NS was not significantly different from the control (P>0,05). The average increase in the honeycomb circumference and the number of honeycombs in control colonies were 37 ± 23.42 cm and 0.75 ± 0.95 pieces (period 1); 172.5 ± 79.65 cm and 3.5 ± 1.73 pieces (period 2). Meanwhile, the colonies fed on PS and NS were 52 ± 55.37 cm and 1.25 ± 1.5 (period 1); 199.5 ± 79.41 cm and 5 ± 2.16 pieces (period 2). The yield of honey produced from colonies fed on PS and NS was higher than control colonies, both in periods 1 and 2. The quality of honey produced by the colony fed on PS and NS met the criteria of the Indonesian National Standard for honey SNI 8664:2018. This study revealed that the provision of PS and NS was able to maintain and increased the productivity of A. cerana colonies, in terms of honeycomb circumference, number of honeycombs, honey yield, and colony strength.

The aims of this study were to obtain yeast isolates, to get species information from honeybee Apis cerana and related substrates, and to determine the effects of a pollen substitute (PS) on the productivity of A. cerana colonies.Yeasts were isolated from A. cerana eggs, larvae, pupae, workers, queens, drones, bee pollen, bee bread, honey, and nectars and pollens from flowers visited by A. cerana. The media used to isolate the yeasts were Yeast-Extract Malt-Extract Agar (YMA) and YMA+50% sucrose.

The yeasts were identified based on sequence data of internal transcribed spacer regions of ribosomal DNA (ITS rDNA). Phylogenetic analysis of yeasts based on ITS rDNA sequence data was performed by the neighbor-joining method. Morphological, physiological and biochemical characteristics of yeasts were observed. To determine the preference of A. cerana for pollen substitutes, honeybee colonies were fed daily with six varieties of pollen substitutes in patty form for 20 days. To examine the effects of pollen substitutes on the productivity of A. cerana, honeybee colonies were fed on local pollen substitutes (PSs) and imported PS for 13 weeks. A total of 1,409 yeast isolates were obtained from various substrates. Fifty representative isolates were selected for identification. The identification results showed that those 50 yeast isolates consisted of 12 genera and 21 species. Six of these genera belong to phylum Ascomycota, and class Hemiascomycetes, while the other six genera belong to phylum Basidiomycota and classes Hymenomycetes, Urediniomycetes and Ustilaginomycetes.

This study indicated that there is an association and an interaction between yeast species and honeybee. The preference test result showed that a PS containing Candida hawaiiana CR015 isolated from the flower of Brugmansia suaveolens (PS1) and a PS containing baker?s yeast (PS4) were favoured by A. cerana colonies.

The productivity test result showed that a PS containing Candida hawaiiana CR015. The preference test result showed that a PS containing Candida hawaiiana CR015 isolated from the flower of Brugmansia suaveolens (PS1) and a PS containing baker?s yeast (PS4) were favoured by A. cerana colonies. The productivity test result showed that a PS containing Candida hawaiiana CR015 isolated from the flower of Brugmansia suaveolens (PS1) was proved to potentially increase the productivity of A. cerana colonies and could be considered as good as imported pollen substitute."

"Penelitian bertujuan membuat pollen substitute (PS) yang disukai dan dapat meningkatkan produktivitas lebah madu A. cerana. Pollen substitute dibuat dengan bahan dasar tepung kedelai dan susu skim. Pada penelitian ini A.cerana diberikan tiga macam pollen substitute, yaitu PS A (mengandung bahan dasar, Debaryomyces hansenii CR133, madu); PS B (mengandung bahan dasar, sirup gula); PS C (mengandung bahan dasar, madu). Pemberian PS selama 20 hari, dan lebah dibiarkan mencari serbuk sari dan nektar di alam. Koloni kontrol tidak diberi PS. Hasil penelitian menunjukkan bahwa PS yang dibuat memenuhi kriteria sebagai PS yang baik. Apis cerana menyukai PS A dan PS C dengan tingkat konsumsi yang lebih tinggi dibandingkan PS B. Pemberian semua jenis PS meningkatkan keliling (0,3--4,5 cm per hari) dan jumlah honeycomb. Pada kontrol terdapat kenaikan keliling honeycomb (0,2--0,5 cm per hari), namun tidak ada penambahan jumlah honeycomb. Secara umum, lebah pekerja yang diberi PS dan kontrol mengalami kenaikan berat badan (5--56,94%).

The research aimed to make pollen substitutes preferred by and increase the productivity of A. cerana. Basic ingredients of pollen substitutes (PS) were soy flour and skim milk. There were three types of pollen substitutes, i.e. PS A (contained basic ingredients, Debaryomyces hansenii CR133, honey); PS B (basic ingredients, sugar syrup); and PS C (basic ingredients, honey). The pollen substitutes were fed to colonies of A. cerana for 20 days, but they were allowed to forage on flowers. No PS was given to the control colonies.

The results showed that A. cerana preferred PSA and PS C to PS A. Increases of circumference and number of honeycombs were observed in colonies fed with all types of PSs (0,3--4,5 cm/day). There was an increase of the circumference of honeycombs in the control (0,2--0,5 cm/day), but there was no addition of new honeycomb. Generally, the weight of individual worker bees increased in colonies fed with PSs and control (5--56,94%)."

"Pada penelitian sebelumnya, diperoleh 18 strain Candida spp. dari Apis cerana dan bunga-bunga yang dikunjunginya di Ciburial, Jawa Barat. Hasil identifikasi berdasarkan data sequence daerah ITS rDNA menggunakan primer reverse ITS4, menunjukkan bahwa 18 strain tersebut memiliki homologi rendah (85--98%) terhadap spesies terdekatnya Candida spp. Dengan demikian belum diperoleh identitas yang akurat dari 18 strain Candida spp. tersebut. Penelitian bertujuan untuk memperoleh identitas yang akurat dari 18 strain tersebut melalui identifikasi molekuler, analisis filogenetik, dan pengamatan karakter fenotipik (morfologi, fisiologi, dan biokimia). Identifikasi dilakukan melalui sequencing pada daerah ITS rDNA dan D1/D2 LSU rDNA. Analisis filogenetik dilakukan berdasarkan data sequence daerah ITS rDNA dan D1/D2 LSU rDNA, menggunakan metode neighbor-joining. Berdasarkan hasil identifikasi molekuler, analisis filogenetik, dan pengamatan karakter fenotipik, 10 strain diidentifikasi ke dalam 5 spesies, yaitu C. parapsilosis (Candida sp. CR033, CR034, dan CR038), C. orthopsilosis (Candida sp. CR015 dan CR151), C. metapsilosis (Candida sp. CR047 dan CR053), Debaryomyces hansenii (Candida sp. CR065), dan Wickerhamomyces anomalus (Candida sp. CR070 dan CR105). Sebanyak 8 strain (Candida sp. CR004, CR007, CR013, CR014, CR018, CR023, CR027, dan CR035) belum dapat ditentukan nama penunjuk (epithet) spesiesnya. Berdasarkan sequence ITS rDNA 8 strain tersebut memiliki homologi yang rendah (97%) terhadap kerabat terdekatnya C. hawaiiana. Pohon filogenetik berdasarkan sequence ITS rDNA menunjukkan 8 strain tersebut berada pada clade yang terpisah dengan C. hawaiiana dengan dukungan nilai bootstrap yang sangat tinggi, 99%. Delapan strain Candida tersebut termasuk dalam satu spesies yang memiliki perbedaan sequence ≤1% antara satu strain Candida dengan strain Candida lainnya atau disebut conspecific. Karakter fisiologi dan biokimia menunjukkan 8 strain tersebut memiliki perbedaan dengan C. hawaiiana CBS 9146T pada kemampuannya mengasimilasi sumber karbon α- methyl -D-glucoside, dan ketidakmampuannya mengasimilasi ribosa. Hasil identifikasi penelitian menunjukkan bahwa 8 strain Candida tersebut merupakan spesies yang berbeda dengan C. hawaiiana.

In the previous study, 18 strains of Candida spp. were obtained from Apis cerana and their visiting flowers in Ciburial, West Java. Based on sequence data of ITS rDNA using ITS4 reverse primer, these strains showed low homology (85--98%) to their closest relatives Candida spp. Therefore, the identity of these 18 strains were not established yet.

The purpose of this study was to establish the identities of the 18 strains of Candida spp. by conducting molecular identification, phylogenetic analysis, and phenotypic characterization (morphological, physiological, and biochemical characters). Identification and phylogenetic analysis was carried out by sequencing the ITS rDNA and D1/D2 of LSU rDNA. Phylogenetic tree was constructed using neighbor-joining method.

Based on molecular identification, phylogenetic analysis, and phenotypic characterization, 10 strains were identified into 5 species. Those 10 strains were identified as C. parapsilosis (Candida sp. CR033, CR034, and CR038), C. orthopsilosis (Candida sp. CR015 and CR151), C. metapsilosis (Candida sp. CR047 and CR053), Debaryomyces hansenii (Candida sp. CR065), and Wickerhamomyces anomalus (Candida sp. CR070 and CR105). The identities of eight strains (Candida sp. CR004, CR007, CR013, CR014, CR018, CR023, CR027, and CR035) were not established yet. Based on sequence data of ITS rDNA they have low degree of homology (97%) to their closest related species, C. hawaiiana.

Phylogenetic tree based on sequence data of ITS rDNA showed they were separated from C. hawaiiana by 99% bootstrap value. Multiple alignment of their sequences of ITS and D1/D2 showed that they have ≤1% differences, which indicate that these strains are conspecific (same species). Their morphological, physiological and biochemical characteristics showed that these strains differed from C. hawaiiana CBS 9146T by their ability to assimilate α-methyl-D-glucoside and their inability to assimilate ribose as carbon sources. Our data suggest that these strains were distinct species from C. hawaiiana."

"Penelitian bertujuan untuk mengetahui pengaruh pemberian pollen substitute (PS) yang dibandingkan dengan pemberian pollen pada Apis mellifera. Sebanyak dua koloni Apis mellifera diberi perlakuan PS (P2 dan P3) setiap minggu selama tujuh minggu. Pollen substitute dibuat dari biomassa basah Candida hawaiiana CR014 yang disajikan dengan gula pasir, dan sari nanas dengan rasio 6: 100: 40 (b/b/v). Sebanyak dua koloni A. mellifera yang digunakan sebagai kontrol positif (K2 dan K3) diberi pakan berupa sari nanas dan pollen setiap minggu selama tujuh minggu. Jumlah larva dan lebah pekerja diamati setiap minggu selama tujuh minggu. Data yang diperoleh dianalisis menggunakan uji Anava satu faktor dan uji T. Secara umum, terjadi penurunan jumlah lebah pekerja pada koloni yang diberi PS dan koloni yang diberi pollen, namun jumlah lebah pekerja pada koloni yang diberi PS tidak berbeda secara signifikan (P>0,05) dengan koloni yang diberi pollen. Jumlah larva pada koloni yang diberi PS tidak berbeda secara signifikan (P>0,05) dengan koloni yang diberi pollen. Pemberian PS dapat menggantikan peran pollen sebagai sumber protein dalam mempertahankan jumlah lebah pekerja dan jumlah larva A. mellifera.

The research aimed to determine the effect of pollen substitute and compared with pollen to feed Apis mellifera. Two colonies (P2 and P3), as a treatment, were each fed with PS once a week during seven weeks experimental period. PS was made of wet biomass of Candida hawaiiana CR014 which served with sugar and pineapple juice with ratio 6: 100: 40 (b/b/v). Two colonies (K1 and K2), as positive control were fed pineapple juice and pollen once a week during seven weeks. The number of larvae and the number of worker were determined every once in a week for seven weeks.

The result were analyzed using one way Anova test and independence T test. Commonly, there were a decrease in the number of worker between colony fed PS and colony fed pollen but there were no significant variations (p>0,05) in the number of worker between colony fed PS compare to pollen. There were no significant variations (p>0,05) in the number of larvae between colony fed PS compare to pollen. PS can replace pollen as source of protein and maintain the number of worker and larvae of A. mellifera."

"Penelitian bertujuan untuk mengetahui pengaruh pemberian PS terhadap jumlah larva, sel madu, volume dan kualitas madu hasil panen. Pemberian PS dapat menggantikan pollen sebagai sumber protein bagi Apis mellifera untuk mempertahankan produktivitas koloninya. Pollen substitute dibuat menggunakan 6 g biomassa basah Candida hawaiiana CR014 dicampur dengan 100 mL sirup nanas. Dua koloni (P.2 dan P.3) sebagai perlakuan diberi PS, sedangkan dua koloni (K.1 dan K.2) sebagai kontrol positif diberi campuran pollen jagung dengan 100 mL sirup nanas, setiap minggu selama enam minggu pada musim kemarau. Jumlah larva dan sel madu diamati setiap minggu selama delapan minggu. Data dianalisis menggunakan uji ANOVA satu faktor, HSD Tukey, dan uji T. Volume dan kualitas madu hasil panen ditentukan pada minggu ketujuh setelah pemberian PS. Rerata jumlah larva pada koloni perlakuan tidak berbeda nyata (P>0,05) dengan kontrol positif. Rerata jumlah sel madu pada koloni perlakuan berbeda nyata (P<0,05) dengan kontrol positif. Volume madu hasil panen dari setiap koloni relatif stabil. Kualitas madu dari koloni perlakuan dan kontrol positif secara umum memenuhi SNI Madu 01-3545-2004, kecuali konsentrasi sukrosa. Pemberian PS selama enam minggu pada musim kemarau dapat mempertahankan produktivitas koloni A. mellifera (jumlah larva, sel madu, dan volume madu yang dihasilkan).

The study aimed to examine the effect of PS on the number of larvae, honey cells, volume and quality of honey yields. Feeding PS can replace pollen as a protein source for Apis mellifera to maintain productivity of colonies. Pollen substitute was made from 6 g of wet biomass of Candida hawaiiana CR014 mixed with 100 mL pineapple sugar. Two colonies (P.2 and P.3) as treatment, were each fed with PS, while two colonies (K.1 and K.2) as positive control, were each fed with 100 mL of a mixture of maize?s pollen and pineapple sugar, once a week for six weeks during dry season. The total number of larvae and honey cells were counted every week for eight weeks.

The results were analyzed using one way ANOVA test, HSD Tukey, and independent T test. The volume and quality of honey yields were determined on seventh week after the PS feeding. The number of larvae in treated colonies was not significantly different (P>0,05) from positive control. The number of honey cells in treated colonies was significantly different (P<0,05) from positive control. The volume of honey yields from each colonies relatively stable. The quality of honey yields from treated colonies and positive control met the National Quality Standard based on SNI 01-3545-2004, except sucrose concentration. It is concluded that feeding of PS for six weeks during dry season could maintain productivity of A. mellifera colonies (the number of larvae, honey cells, and volume of honey yields)."

"Penelitian bertujuan untuk mengetahui pengaruh pemberian pollen substitute (PS) mengandung biomassa C. hawaiiana CR014 terhadap jumlah larva dan pupa lebah pekerja A. mellifera. Sebagai kontrol positif koloni lebah madu diberi pakan tambahan pollen jagung. Pemberian pakan dilakukan sekali seminggu selama enam minggu pada musim kemarau. Hasil uji ANOVA satu faktor menunjukkan bahwa rerata jumlah larva yang dihasilkan per minggu pada koloni perlakuan dan koloni kontrol positif tidak berbeda nyata (P>0,05). Begitu pula dengan rerata jumlah pupa pada koloni perlakuan dan kontrol positif per minggu tidak berbeda nyata (P>0,05). Hasil uji T juga menunjukkan bahwa rerata jumlah larva dan pupa per minggu antara koloni perlakuan dan koloni kontrol positif tidak berbeda nyata (P>0,05). Pemberian PS pada A. mellifera memberikan pengaruh yang hampir sama baiknya dengan pemberian pollen jagung terhadap jumlah larva dan pupa lebah pekerja A. mellifera selama periode pengamatan tujuh minggu. Hasil penelitian memperlihatkan bahwa PS yang mengandung biomassa C. hawaiiana CR014 dapat menggantikan peran pollen alami sebagai sumber protein A. mellifera untuk mempertahankan produktivitas koloninya pada musim kemarau.

The research aimed to examine the effect of pollen substitute (PS) containing Candida hawaiiana CR014 on the number of larvae and pupae of worker bees Apis mellifera. Colonies of a positive control were fed with maize?s pollen. The colonies were fed once a week for six weeks in the dry season. The one-way Anova test showed that the mean number of larvae produced per week in the treated group were not significantly difference from the positive control (P> 0,05). Similarly, the mean number of pupae produced per week in treated group and the positive control were not significantly difference (P>0,05).

The T-test showed that the mean number of larvae and pupae per week between the treated group and the positive control were not significantly difference (P>0,05). The study indicated that PS and the maize?s pollen has an almost similar effect on the number of larvae and the number of pupae of worker bees produced by the colonies during the experiment. It is concluded that PS containing C. hawaiiana CR014 might be used to replace natural pollens as a protein source to maintain productivity of A. mellifera during the dry season."

"Produksi madu dari peternakan lebah di Irian Jaya, khususnya kabupaten Jayapura menurun dengan drastis disebabkan oleh adanya infestasi tungau Tropilaelaps clereae dan Varroa jacobsoni dan adanya protozoa Nosema apis. Infestasi T.clareae hanya ada pada satu koloni Apis mallifera, sedangkan Varroa jacobsoni pada koloni Apis cerana. Infestasi T.clereae pada 14 koloni A.mellifera yang diamati bervariasi antara 0% - 59%, sedangkan derajat infestasi V.jacobsoni antara 0,59% - 1,2%. Nosema apis ditemukan pada 2 koloni A.mellifera. Pemakaian campuran belerang dan kamper dapat memberantas tungau belum digunakan oleh peternak lebah dengan perbandingan yang tepat ( 2 gram belerang dan 1 gram kamper) serta dengan jadwal yang tertentu, sehingga campuran tersebut tidak bekerja dengan hasil yang memuaskan."
