Frankliniella occidentalis

Two major components have been detected from adult male western flower thrips, Frankliniella occidentalis Pergande (Thysanoptera Thripidae) that are not present in females. They were identified as (i )-lavandulyl acetate and neryl (5)-2-methylbutanoate. The catch of males and females on traps was significant by the butanoate alone or by a 1 1 blend of the acetate and the butanoate, but the acetate was not active alone.

The behavioural responses of adult female western flower thrips, Frankliniella occidentalis, to volatiles from meadowsweet (Filipendula ulmaria), bay laurel and sage (Salvia officinalis) were investigated in laboratory bioassays by Chermenskaya et al. (2001). Volatiles collected by entrainment of a solvent extract of F. ulmaria were more attractive than was the original extract. F. occidentalis also was attracted significantly to volatiles from L. nobilis and S. officinalis. Analysis by gas chromatography and mass spectrometry identified 1,8-cineole (euca-lyptol) as one of the main volatile components of all three plant species. In coupled...

Walling, 2000), less is known about plant responses to sucking or piercing insects (Du et al, 1998 Williams HI et al, 2005) (see Section on Regulation of Plant Toxicants by Natural Activators ). A recent study of the interactions between different types of herbivorous insects and plant defence volatiles showed that tobacco, Nicotiana tabacum, releases terpenoids and nicotine after caterpillar regurgitate treatment. Colonisation by western flower thrips, Frankliniella occidentalis, was reduced on the regurgitate treated plants, possibly due to the production of nicotine (Delphia et al, 2007).
