Less is more: partial larvicidal efficacy of plant leachate leads to larger Aedes aegypti mosquitoes Bull. Entomol. Res. (IF 1.9) Pub Date : 2023-08-07 Isabella Bodanese Marsaro, Gilberto Dinis Cozzer, Emanuel Rampanelli Cararo, Raquel De Brito, William Gabriel Borges, Jacir Dal Magro, Cássia Alves Lima-Rezende, Renan de Souza Rezende
Major efforts to control the population of Aedes aegypti mosquitoes involve the use of synthetic insecticides, which can be harmful to the environment. Most plant compounds are eco-friendly and some of them have biocontrol potential, whereas a fraction of these compounds is released into the environment through the leaf-leaching process. We evaluated the effects of secondary compounds from Ateleia

Detection and substrate portrayal on the serum phenoloxidase activity from the grub of rhinoceros beetle, Oryctes rhinoceros Bull. Entomol. Res. (IF 1.9) Pub Date : 2023-07-31 Balashanmuga Nehru Marieshwari, Chandran Prithi, Ramanathan Nivetha, Sreeramulu Bhuvaragavan, Janarthanan Sundaram
Phenoloxidase (PO) is a significant biomolecule involved in humoral defence mechanism of invertebrates. Spontaneous melanization of insect haemolymph is the major hinderance for studying PO activity, as haemolymph was collected devoid of phenylthiourea. In the study, no visible melanization was observed in crude serum from the grub of Oryctes rhinoceros up to 30 min of incubation amongst crude haemolymph

Rapid cold hardening and cold acclimation promote cold tolerance of oriental fruit fly, Bactrocera dorsalis (Hendel) by physiological substances transformation and cryoprotectants accumulation Bull. Entomol. Res. (IF 1.9) Pub Date : 2023-07-28 Zifei Xie, Luchen Xu, Jie Zhao, Na Li, Deqiang Qin, Chun Xiao, Yongyue Lu, Zijun Guo
Insect response to cold stress is often associated with adaptive strategies and chemical variation. However, low-temperature domestication to promote the cold tolerance potential of Bactrocera dorsalis and transformation of main internal substances are not clear. Here, we use a series of low-temperature exposure experiments, supercooling point (SCP) measurement, physiological substances and cryoprotectants

Light has a substantial effect on the behaviour and physiology of nocturnal moths. Ectropis grisescens is a major nocturnal tea pest in China, and light traps are commonly used to control geometrid moths because of their positive phototaxis. However, some moths gather around light traps and enter the light adaptation state, which decreases the efficacy of light traps in controlling this pest. We identified
