Genetic manipulations of neuronal activity are a cornerstone of studies aimed to identify the functional impact of defined neurons for animal behavior. With its small nervous system, rapid life cycle, and genetic amenability, the fruit fly Drosophila melanogaster provides an attractive model system to study neuronal circuit function. In the past two decades, a large repertoire of elegant geneti...

We investigated whether adult fruit flies (Drosophila melanogaster) use cues of larvae as social information in their food patch choice decisions. Adult male and female fruit flies showed attraction to odours emanating from foraging larvae, and females preferred to lay eggs on food patches occupied by larvae over similar unoccupied patches. Females learned and subsequently preferred to lay eggs...

Drosophila melanogaster born and reared in constant darkness exhibit circadian locomotor activity rhythms as adults. However, the rhythms of the individual flies composing these populations are not synchronized with one another. This lack of synchrony is evident in populations of flies commencing development at the same time, indicating that a biological clock controlling circadian rhythmicity ...

Proprioception is the ability to sense the motion, or position, of body parts by responding to stimuli arising within the body. In fruitflies and other insects proprioception is provided by specialized sensory organs termed chordotonal organs (ChOs). Like many other organs in Drosophila, ChOs develop twice during the life cycle of the fly. First, the larval ChOs develop during embryogenesis. Th...

Sistem Pertanian Terpadu (SPT) dalam pengabdian ini ditujukan untuk mengatasi permasalahan pemenuhan pakan ternak ayam dan ikan akibat harga yang semakin tinggi tiap tahunnya, sekaligus pengurangan limbah organik hasil pertanian rumah tangga melalui pemanfaatan larva (maggot) Black Soldier Fly. Pengabdian dilakukan secara bertahap dari perencanaan, persiapan, sosialisasi, pelaksanaan pemantauan...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

Abstract The objective of the present study was to determine standardized total tract digestibility phosphorus (P) in black soldier fly (BSF; Hermetia illucens) larvae fed pigs. Test ingredients were fish meal (66.2% crude protein, 9.2% ether extract, and 2.63% P), 3 sources defatted BSF larva (43.1 59.2% 8.6 13.2% 0.91 1.06% a source full-fat (34.2% 36.0% 0.70% P). Six barrows with an initial ...

Toman fish is a pure carnivore which so far has used wild catches as its entire diet. Alternative feed with high animal protein and easy to obtain needs be done. Fermentation activities using tempe yeast can usually increase the content of material. Studies on use fermented maggot for toman seed have not yet obtained sufficient information, in-depth research this matter really This study aims a...

Tujuan dari penelitian ini adalah untuk mengetahui perbedaan biokonversi sampah buah dan sayur menggunakan larva BSF (Hermetia illucens). Penelitan merupakan eksperimen yang Rancangan Acak Lengkap (RAL). Larva digunakan telah berumur 6 hari. 5 perlakuan perbandingan dengan tertentu. Analisis data uji kruskal wallis dilanjutkan mann-whitneey derajat kepercayaan α=0,05. Hasil analisis menunjukkan...
