Cysteine peptidases and their inhibitors in Tetranychus urticae: a comparative genomic approach [PDF]
BMC Genomics, 2012 Abstract Background Cysteine peptidases in the two-spotted spider mite Tetranychus urticae are involved in essential physiological processes, including proteolytic digestion. Cystatins and thyropins are inhibitors of cysteine peptidases that modulate their activity, although their function in this species has yet to ...

Chemistry &Biodiversity, EarlyView.The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (

Insecticides outweigh rye cover crop in triggering secondary pest outbreaks
Pest Management Science, EarlyView.Insecticides outweigh rye cover crop in triggering secondary pest outbreaks. Zeus Mateos‐Fierro*, Ashley Leach, Ian Kaplan. Spider mite and melon aphid outbreaks are enhanced with broad‐spectrum insecticides, while natural enemies are reduced. However, rye cover crop has little effect on either pest or natural enemy populations.
