Abstract

The herbivorous ladybird beetle Henosepilachna vigintioctopunctata depends primarily on solanaceous plants. The utilisation of a novel fabaceous host, centro (Centrosema molle), by this beetle has been reported from several regions in Southeastern Asia, but details of the distribution and feeding habits of H. vigintioctopunctata populations on centro are largely unknown. Our study aimed to gather basic information on the utilisation of centro by H. vigintioctopunctata in the Nusa Tenggara region of southeastern Indonesia. Field surveys indicated that H. vigintioctopunctata did not yet utilize centro in the wild in this region. However, in feeding-choice experiments in the laboratory, all beetle populations tested from this region had some potential to utilize centro, i.e., showed some feeding acceptance of this plant. Based on these results, we discuss the current status of the Nusa Tenggara H. vigintioctopunctata populations in using centro as a host.

Abstract

Host specificity has been a major factor in generating the tremendous diversity of phytophagous arthropods. Studies of adaptation to introduced or invasive plant species provide an opportunity to investigate incipient evolutionary changes in host specificity. We investigated the cryptic ability of the Asian tropical herbivorous ladybird beetle Henosepilachna diffinis to feed on the fabaceous weed "centro", Centrosema molle, which was introduced to Southeast Asia about 200 years ago. In laboratory choice tests using this plant and the normal host plant, Solanum torvum, adults preferred S. torvum to centro, but over half the beetles tested ate leaves of both plants. Furthermore, most first-instar larvae accepted centro during a rearing experiment, and a few of them grew to the third-instar stage, though none reached the final (fourth) instar. Henosepilachna diffinis likely acquired this incomplete acceptability of centro without any direct host-grazer interaction with centro, probably before this weed was introduced to Southeast Asia. Our results further suggest that another Henosepilachna species, H. vigintioctopunctata, might similarly have already acquired an incomplete ability to use centro when this beetle encountered it for the first time, and this triggered a subsequent host-range expansion from solanaceous plants to include centro in various parts of Southeast Asia.

Abstract

A study on seasonal migration of the tropical honeybee, Apis dorsata wasconducted in the protected habitat of the Bogor Botanic Garden, West Jawa, Indonesia by monitoring the arrivals and departures of colonies of the honeybee. The colonies arrived in the garden during both the higher mean monthly rainfall and the lower number of rainy days per month and departed during the time of increasing the number of both total monthly rainfall and monthly rainy days. During their stay in the garden, the colonies occupied a certain location and host plant patches. Their duration of stay in the garden was variable. It was 77%, 9% and 4% of the colonies developed, stable and decreased their colony member, respectively. The colonies (23%) performed reproduction by reproducing new queens. Early arriving colonies stayed in very long periods and reproduced colony fission.

Abstract

Thirteen species of macrochelid mites belonging to the genera Holostaspella, Macrocheles, Neopodocinum and Glyptholaspis were collected from a nest of honey bee Apis dorsata dorsata at Bogor Botanical Garden, Bogor, West Java, Indonesia. Of these, one species was described as new to science, two species were recorded from Indonesia for the first time, and all species were recorded from nest of Apis dorsata dorsata for the first time. Macrocheles nidus sp. nov. is similar to some species of scutatus subgroup, but it is discernible from the latter by the pilosity of dorsal setae.

Abstract

Divergent adaptation to different host plants may promote reproductive isolation between hostspecific populations in phytophagous insects, since strict preferences for different host plants act as an isolating barrier between populations on the different hosts. Moreover, a high dependence on the host plants may cause additional reproductive barriers, e.g., differences in micro-spatial distribution and phenology between host-specific populations when the host plants differ in these characters. However, few studies have specifically addressed these two types of host-plant-induced isolating barriers. Here we compared the microspatialdistribution and seasonal fluctuation of two host races of the  phytophagous ladybird beetle Henosepilachna diekei (Coleoptera: Coccinellidae: Epilachnine) in Bogor, West Java, one depending onMikania micrantha (Asteraceae) and the other on Leucas lavandulifolia (Lamiaceae). In the field, M. micrantha was far more abundant and common than L. lavandulifolia throughout the year. M. micrantha wasfound in relatively moist habitats with moderate sunlight, while L. lavandulifolia was found in dry, sunny, open habitats. Consequently, the beetles depending on M. micrantha were more common and abundant than those depending on L. lavandulifolia. Although the two host races could encounter one another where the two host plants occurred in close proximity, they infrequently did so because of strict host fidelity coupledwith differences in the abundance and habitat of the two host plants. On the other hand, we detected no evidence of host-related seasonal isolation between the two host races.Key words: host race, host shift, micro-spatial distribution, phenology, seasonal fluctuation

Abstract

Bunga kelapa sawit bersifat monoceus. Penyerbukannya dapat terjadi oleh bantuan serangga penyerbuk. Kumbang Elaeidobius kamerunicus adalah penyerbuk spesialis, yang bersama dengan jenis-jenis serangga lain melakukan penyerbukan kelapa sawit. Pengelolaan penyerbukan kelapa sawit di setiap perkebunan berbeda karena serangga penyerbuknya pun berbeda sehingga perlu disesuaikan dengan kondisi lingkungan masing-masing. Tidak ada publikasi tentang serangga penyerbuk lokal pada kelapa sawit di Indonesia selain oleh kumbang E. kamerunicus. Pada penelitian ini ditemukan serangga penyerbuk kelapa sawit lainnya, disamping E. kamerunicus, yaitu enam jenis lebah yang terdiri dari Apis florea, A. cerana, A. koschevnicovi, Trigona laeviceps, T. melina, dan T. itama yang mengunjungi bunga jantan anthesis dan betina receptive. Berdasarkan analisa ukuran dan perilaku kunjungan pada bunga betina disimpulkan bahwa hanya tiga jenis A. florea, Trigona laeviceps, dan T. melina yang mempunyai potensi tinggi sebagai penyerbuk bunga kelapa sawit pada bagian permukaan bunga. Sedangkan kumbang E. kamerunicus lebih berperan sebagai penyerbuk bagian dalam dari perbungaan. Populasi kumbang E. kamerunicus per hektar relatif rendah yang menyebabkan sebanyak 35,1% buah kelapa sawit yang tidak berkembang. Pemanfaatan kumbang E. kamerunicus untuk penyerbukan buatan telah dilakukan oleh petani kelapa sawit, namun dilakukan dengan cara yang menimbulkan banyak kematian pada kumbang muda.

Abstract

Elaeidobius kamerunicus (kumbang sawit) adalah penyerbuk utama dari bunga kelapa sawit. Kondisi populasi kumbang sawit dalam suatu lingkungan perkebunan kelapa sawit sangat menentukan tingkat keberhasilan dari produksi buah. Faktor-faktor yang mempengaruhi kondisi populasi kumbang sawit, selain dari faktor internal, juga dari varietas tanaman, pola cocok tanam, pemupukan, dan pengendalian hama terpadu serta kondisi lingkungan fisik dan biotik. Lingkungan fisik salah satunya adalah iklim, sedangkan lingkungan biotik adalah musuh alami yaitu predator dan parasitoid. Penelitian tentang peran lingkungan biotik terhadap populasi kumbang sawit dilakukan pada musim hujan dan musim kemarau di perkebunan kelapa sawit di Kabupaten Penajam Paser Utara, Kalimantan Timur. Ditemukan sebanyak 7 jenis predator yang terdiri dari: 2 jenis burung, 5 jenis serangga (semut Odontoponera denticulata (Formicidae), cecopet Chelisoches morio (Chelisochidae), kepik Velinus nigrigenu (Reduviidae), dan tawon Vespa affinis, V. bellicosa (Vespidae)). Sebanyak 10 jenis tawon parasitoid juga ditemukan (Evaniidae 1 jenis, Braconidae 2, Scelionidae 2, Eulophidae 2, Chalcididae 1, Mymaridae 1, dan Ormyridae 1). Namun, potensi sebagai musuh alami penyerbuk kelapa sawit masih memerlukan penelitian lebih lanjut. Dipertelakan ekologi perilaku dari setiap jenis musuh alam dari kumbang sawit sehingga diketahui tingkat potensinya sebagai pengontrol populasi kumbang sawit.
