Toxicity and Field Efficacy of Four Neonicotinoids on Harlequin Bug (hemiptera: Pentatomidae)
Harlequin bug, Murgantia histrionica (Hahn), is a pest of cole crops in the USA. Laboratory toxicity assays revealed that the neonicotinoid insecticides imidacloprid, thiamethoxam, dinotefuran, and clothianidin are toxic to harlequin bug nymphs; LC50 = 0.57, 0.52, 0.39, and 0.39 ppm, respectively. Field experiments were conducted to evaluate the efficacy of these insecticides over time when app...
متن کاملHost plant preference of harlequin bug (Hemiptera: Pentatomidae), and evaluation of a trap cropping strategy for its control in collard.
Harlequin bug, Murgantia histrionica (Hahn) (Hemiptera: Pentatomidae), is a piercing-sucking pest of cole crops, causing cosmetic damage in low populations, while heavy pest pressure can kill plants or entire fields. Field studies were conducted to evaluate a trap crop for control of harlequin bug in collard. Field-cage choice tests found that potential trap crop plant species, mustard (Brassic...
متن کاملIs the hibiscus harlequin bug aposematic? The importance of testing multiple predators
Aposematism involves predators learning conspicuous signals of defended prey. However, prey species utilize a wide range of chemical (or physical) defenses, which are not likely to be equally aversive to all predators. Aposematism may therefore only be effective against a physiologically sensitive subset of potential predators, and this can only be identified through behavioral testing. We stud...
متن کاملA Transcriptome Survey Spanning Life Stages and Sexes of the Harlequin Bug, Murgantia histrionica
The harlequin bug, Murgantia histrionica (Hahn), is an agricultural pest in the continental United States, particularly in southern states. Reliable gene sequence data are especially useful to the development of species-specific, environmentally friendly molecular biopesticides and effective biolures for this insect. Here, mRNAs were sampled from whole insects at the 2nd and 4th nymphal instars...
