Thrips tabaci Lindeman (Thysanoptera: Thripidae), a cosmopolitan pest insect, is subdivided into at least three genetic lineages that have different biological characters, such as reproductive mode and resistibility to insecticides. Since the lineages are discriminated only by mitochondrial DNA, there is a possibility of gene flow among lineages at the genomic level. Nine polymorphic microsatel...

Ethyl formate applied as an aerosol killed almost 100% of the mould mites (Tyrophagus putrescentiae) present in tissue culture tubs. Mite mortality showed dose responses to the chemical and mortality increased with duration of exposure. Other aerosol formulations, and vacuum and controlled atmosphere treatments were also tested but were not effective in controlling mites. Onion thrips (Thrips t...
