Comments on “Parasitic strategies of arthropods of medical and veterinary importance”: Di Giovanni et al. (2021) Entomol. Gen. (IF 6.9) Pub Date : 2023-09-25 Louwrens P. Snyman, Emily J. Jenkins
Recently, Di Giovanni et al. (2021) reviewed three parasitic strategies employed by terrestrial arthropods of medical and veterinary importance: (1) trophic transmission, (2) direct transmission, and (3) micropredators, subdivided into short- and long-term. The use of direct as both a transmission strategy and a life cycle descriptor is confusing, and we prefer the widely accepted term monoxeny for

Is it safe for honey bee colonies to locate apiaries near wind turbines? Entomol. Gen. (IF 6.9) Pub Date : 2023-09-25 Julie Fourrier, Ophélie Fontaine, Maïlys Peter, Julien Vallon, Fabrice Allier, Benjamin Basso, Axel Decourtye
Wind energy is considered as one of the most promising renewable energy sources. However the growth in wind farms over the last few years raises questions about the possible effects on ecosystems. The widely documented impacts on birds and bats have garnered much attention. On the other hand, few studies exist concerning the impact on insects, and notably pollinators, despite the essential pollination

Halloween genes as optimal RNAi-based targets for controlling the cigarette beetle, Lasioderma serricorne Entomol. Gen. (IF 6.9) Pub Date : 2023-09-25 Yi Yan, Zhi-Jun Le, Hong Yang, Kang-Kang Xu, Can Li, Wen-Jia Yang
As an important insect endohormone, 20-hydroxyecdysone (20E) plays a key role in regulating the metamorphosis and development of insects, and the Halloween genes are involved in 20E biosynthesis. However, the function of Halloween genes in Lasioderma serricorne, a major pest of stored products worldwide, remains unknown. Here, five Halloween genes from L. serricorne, namely LsCYP307A1, LsCYP302A1,

Identification of ABCG transporter genes associated with multi-insecticide resistance in Plutella xylostella (L.) Entomol. Gen. (IF 6.9) Pub Date : 2023-09-06 Jinqiong Shan, Bin Zhu, Pei Liang
Plutella xylostella (L.) is the most severe pest that feeds on cruciferous plants. With the widespread and long-term use of insecticides, P. xylostella has developed resistance to almost all kinds of insecticides, and multi-insecticide resistant populations are frequently reported. However, the mechanisms of multi-resistance in P. xylostella remain unknown. ATP-binding cassette (ABC) transporters,

Long-term changes in pest resistance dynamics in China and Australia in response to the introduction of Bt cotton and patterns of insecticide use Entomol. Gen. (IF 6.9) Pub Date : 2023-09-06 Huaizhi Zhao, Sharon Downes, Lisa Bird, Myron P. Zalucki, Yinjun Fan, Zongming Xie, Munir Ahmad, Zhaozhi Lu
Crops expressing insecticidal crystal proteins of Bacillus thuringiensis (Bt), often provide an opportunity for lower resistance selection toward synthetic pesticides due to reduced spraying frequency and the subsequent significant increase of natural enemies for the control of secondary pests. We would therefore expect declines in insecticide resistance levels. We analyzed patterns of resistance to
