Understanding environmental factors affecting the timing and rate of animal development, as well as the factors that cause their effects, is of great importance. The purpose of this study was to establish the relationship between the onset and duration of the development from egg to pupal stage and water temperature in three black fly (Diptera: Simuliidae) species: Simulium (Simulium) reptans (...

Larva Black Soldier Fly (BSF) dikenal sebagai agen pendegradasi bahan organik. Kemampuan hidup di lingkungan yang kaya mikorba seperti limbah organik tentu menuntut sistem kekebalan tubuh kuat dari larva BSF. BSF (Hermetia illucens) berpotensi sumber agensia hayati karena akan mikroorganisme. Penelitian ini bertujuan mengisolasi dan seleksi bakteri bersifat antagonis terhadap Rhizoctonia solani...

Here, we describe a nano-scale surface structure on the rat-tailed maggot, the aquatic larva of the Drone fly Eristalis tenax(L.). Larvae of this syrphid hover fly live in stagnant, anaerobic water-courses that are rich in organic matter. The larvae burrow into fetid slurry and feed on microorganisms which they filter out from the organic material. This environment is rich in bacteria, fungi an...

Phlebotomine sand flies are vectors of bacteria, parasites, and viruses. Lutzomyia apache, a North American sand fly, was incriminated as a vector of vesicular stomatitis viruses (VSV) due to overlapping ranges of the sand fly and recent outbreaks of VSV. We report on the discovery of 2 populations of L. apache in Wyoming from Albany and Fremont counties. We attempted to isolate VSV and phlebov...

Genomic sequencing efforts can implicate large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system to validate candidate gene association with pathology is therefore useful. We present such a system employing Drosophila to validate candidate congenital heart disease (CHD) genes. The protocols exploit comprehensive libraries of UAS-Gen...

Permasalahan sampah kini menjadi hal yang sudah cukup sulit untuk diselesaikan. Populasi semakin meningkat mengakibtakan volume besar. Bukan hanya anorganik, oraganik-pun masalah lingkungan belum adanya pengolahan secara maksimal faktor utamanya. Namun penelitian dan pengembangan terkait mulai ditingkatkan. Dan salah satu solusi permasalahan organik tengah ramai adalah menggunakannya sebagai me...

A reduced sensitivity to the sedating effects of alcohol is a characteristic associated with alcohol use disorders (AUDs). A genetic screen for ethanol sedation mutants in Drosophila identified arouser (aru), which functions in developing neurons to reduce ethanol sensitivity. Genetic evidence suggests that aru regulates ethanol sensitivity through its activation by Egfr/Erk signaling and its i...

Simulium yahense black flies infected with microfilaria of Onchocerca volvulus were kept in a defined insectary environment in Liberia, West Africa. A daily sample of infected flies was dissected for larvae developing in the thoracic muscles and examined for growth in stadial development. Microfilariae ingested by black flies transformed to the L1 larval stage without molting. Successive larval...

A new interaction between insects and carnivorous plants is reported from Brazil. Larvae of the predatory flower fly Toxomerus basalis (Diptera: Syrphidae: Syrphinae) have been found scavenging on the sticky leaves of several carnivorous sundew species (Drosera, Droseraceae) in Minas Gerais and São Paulo states, SE Brazil. This syrphid apparently spends its whole larval stage feeding on prey tr...
