Published: 06 May 2021
...Yan Wang; Sirisha Burra; Michael J. Galko ABSTRACT Holometabolous insects undergo a complete transformation of the body plan from the larval to the adult stage. In Drosophila , this transformation includes replacement of larval epidermal cells (LECs) by adult epidermal cells (AECs). AECs in...

... species Drosophila melanogaster exhibit aggression in same-sex pairings, but the strategies used are sexually dimorphic. We have begun to explore the biological basis for the differing aggression strategies, and the cues promoting one form of aggression over the other. Here, we describe a line of...

... system and several behavioural aspects in insects. In particular, tyramine (TA) and octopamine (OA) and their associated receptors orchestrate physiological processes such as feeding, locomotion and metabolism. Here, we show that monoterpenes not only act as biopesticides in Drosophila species but also...
