Abstract Pyrethrum extracts from flower heads of Chrysanthemum spp. have been used worldwide in insecticides and repellents. While the molecular mechanisms its insecticidal action are known, basis pyrethrum repellency remains a mystery. In this study, we find that principal components pyrethrum, pyrethrins, minor component, (E)-β-farnesene (EBF), each activate specific type olfactory receptor neurons Aedes aegypti mosquitoes. We identify Ae. odorant 31 (AaOr31) as cognate Or for EBF...
Background Volatile pyrethroid insecticides, such as transfluthrin, have received increasing attention for their potent repellent activities in recent years controlling human disease vectors. It has been long understood that pyrethroids kill insects by promoting activation and inhibiting inactivation of voltage-gated sodium channels. However, the mechanism repellency remains poorly controversial. Methodology/Principal findings Here, we show transfluthrin repels Aedes aegypti a hand-in-cage...
Abstract Spodoptera frugiperda invaded China in the end of 2018 and has caused severe damage to maize other crops. Several S. naturally parasitized by nematodes were observed Hainan Province, China. The morphological characteristics based on results scanning electron microscopy indicated that nematode belongs family Mermithidae. Additionally, coding sequences for 18 S 28 rDNA amplified from genome, phylogenetic analysis revealed Ovomermis sinensis , a known entomoparasitic nematode. Our...
Abstract BACKGROUND Apolygus lucorum (Meyer‐Dür) is a serious worldwide agricultural pest, especially for Bt cotton in China. Pyrethroids, neonicotinoids and organophosphates are the most effective insecticides to control piercing sucking insects, including A. . The voltage‐gated sodium channel (Na v ) major target site of pyrethroids. Extensive alternative splicing RNA editing, two post‐transcriptional mechanisms, contribute generate different functional variants. In our research, we...
We conducted a study on the control of mosquitos Chisi Island in Lake Chilwa from August to November, 2006. The aim was compare cost and efficacy deltamethrin, pyrethroid based insecticide, when used insecticide treated nets (ITN) indoor residual spray (IRS). Thirty village huts were enrolled study. Fifteen systematically selected stratified manner sprayed with deltamethrin following manufacturers' standard application procedures 0.02g/m2. remaining fifteen provided ITNs. In both groups KO...
