In the eusocial honey bee Apis mellifera, with reproductive queens and sterile workers, a female larva's developmental fate depends on its diet; nurse bees feed queen-destined larvae exclusively royal jelly, a glandular secretion, but worker-destined larvae receive royal jelly for 3 days and subsequently jelly to which honey and beebread are added. RNA-Seq analysis demonstrated that p-coumaric ...

Five pools containing immature stages of Anopheles punctulatus were treated with pyriproxyfen at 4 different dosages. Inhibition of adult emergence was observed in pupae collected from the test pools and/or those obtained by rearing of the 4th instar larvae. Adult emergence was inhibited completely for 2 months at a dosage of 0.1 ppm, for one month at 0.05 ppm and 0.01 ppm, and for 20 days at 0...

Serotonin (5-HT) is known to modulate motor outputs in a variety of animal behaviors. However, the downstream neural pathways of 5-HT remain poorly understood. We studied the role of 5-HT in directional change, or turning, behavior of fruit fly (Drosophila melanogaster) larvae. We analyzed light- and touch-induced turning and found that turning is a combination of three components: bending, ret...

Abstract. The growth rate of Hermetia illucens larvae in the bioconversion organic waste is influenced by media and environmental conditions where BSF lives. This study aims to determine effect feed formula on waste. research method was carried out rearing larvae, making formulas, determining larval length, weight cassava. results showed that feeding from fish waste, tapioca with a chopped diam...

Fleas Xenopsylla conformis mycerini and Xenopsylla ramesis replace each other on the same rodent host (Meriones crassus) in two habitats that differ in substrate texture (sand and loess-like sediments, respectively). We hypothesized that the substrate is an important factor determining flea distribution and studied survival of larvae, pupae and newly emerged adults as well as the rate of pre-im...
