Regulatory mechanisms of reproduction in locusts and grasshoppers
Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

ABSTRACT The Western honey bee (Apis mellifera) is a globally important pollinator. Its health in natural and managed populations is compromised by numerous factors, including pesticides. Neonicotinoid pesticides are widely used even though they can cause a variety of detrimental effects.

Farnesol, the sesquiterpenoid precursor of insect juvenile hormones (JH) that itself has JH activity, existed already long before animals and their hormones came into being.

CONTROL OF CORPORA ALLATA FUNCTION IN LARVAE OFGALLERIA MELLONELLA
1. The implantation of three brains into freshly ecdysed last instar larvae which possess at least one of the two corpora allata induces extra larval development. Implanted brains appear to produce a neurohumoral allatotropic factor.2. Corpora allata seem to be inhibited via their nervous connections 48-60 hours after the last larval-larval ecdysis and

Diet acts on sexual behavior development in a male moth
Drastic changes are observed during sexual maturation characterized by the reproductive system development concomitantly to the sexual behavior ontogenesis. These modifications are under the control of internal and external factors such as food. Knowing that sexual maturation requires considerable energetic investment, diet has been shown to affect ...

NERVOUS AND HORMANAL FACTORS AFFECTING THE REPRODUCTIVE EFFICIENCY OF Spodoptera littoralis FEMALE MOTHS [PDF]
Mating process in Spodoptera littoralis female moths started 2 – 3 hrs after light off and the peak of mating was noticed 6.30 – 7.30 hrs after starting the scotophase period.

Abstract Natural variation can provide important insights into the genetic and environmental factors that shape social behaviour and its evolution. The sweat bee, Lasioglossum baleicum, is a socially flexible bee capable of producing both solitary and eusocial nests.

In CLas‐infected D. citri, CLas lowers 20E levels initially, relieving the suppression of ETH release. The subsequent increase in ETH levels upregulates its receptor DcETHR and activates the JH signaling pathway. The signaling cascade of 20E‐ETH/ETHR‐JH along with miR‐210, targeting DcETHR, boost female fecundity in CLas+ D.

We applied s‐hydroprene, a juvenile hormone analog (JHA), to gravid female mosquitoes that have naturally ceased JH production. We found that gravid females exposed to JHAs blood fed in a dose dependent manner and this behavior could be induced through simulated environmental exposure.

The moulting arthropod: a complete genetic toolkit review
ABSTRACT Exoskeletons are a defining character of all arthropods that provide physical support for their segmented bodies and appendages as well as protection from the environment and predation. This ubiquitous yet evolutionarily variable feature has been instrumental in facilitating the adoption of a variety of lifestyles and the exploitation of ...
