The number of eggs laid by female western flower thrips, Frankliniella occidentalis (Pergande), and female tobacco thrips, F. fusca (Hinds), were collected from combination of TSWV-infected and non-infected tomato, Lycopersicon esculentum Mill. cv. ‘Sunny hybrids’ and TSWV-infected and non-infected chickweed, Stellaria media (L.) Cyrillo) in greenhouse cages during June-July 2002. Number of observed eggs, calibrated with a stained sub-sample, on leaves as well as number of immature thrips from host plants are reported and discussed.

Species 1: Thysanoptera Thripidae Frankliniella occidentalis (Western flower thrips)
Species 2: Thysanoptera Thripidae Frankliniella fusca (Tobacco thrips)
Keywords: Tomato spotted wilt virus, Oviposition
