Situation of Liriomyza sativae in Venezuela

In Venezuela, Liriomyza sativae (EPPO A1 quarantine pest) is considered as a secondary pest of tomato. However, during the last 10 years pest populations have increased considerably, leading to problems in the majority of the tomato-growing regions in the country. In order to evaluate the population fluctuations, field studies have been carried out at the 'Estación Experimental Samán Mocho de la Universidad Central' (State of Carabobo) in three different periods of the year: dry season (October-December 1985), end of dry season beginning of rainy season (March-May 1986), and rainy season (July-September 1986). Highest numbers of leaf miners were observed at the end of the dry season. The following parasitoids have been found: Chrysonotomyia sp. Closterocerus sp., Diglyphus sp., Chrysocaris sp., Omphale sp., Haltioptera, Cothonaspis sp. and Opius sp. and were in highest numbers at the end of the dry season and beginning or the rainy season.
