Biological control of pests in cucumbers in 1997-1998 has been very successful. More than 95/ of the Dutch cucumber growers are using IPM. Control of cotton aphids (Aphis gossypii) using banker plants of wheat with Rhopalosiphum padi and Aphidoletes aphidimyza has proved to be effective. Amblyseius limonicus has been shown to be a good predatory mite for biological control of thrips, however, a commercial rearing system has not been found. A previously undescribed Franklinothrips spp. has been tested for biological control of western flower thrips (Frankliniella occidentalis) in cucumbers and initial results are promising. Some remaining battlenecks in biological control in cucumber are the rapid population development of cotton aphids (Aphis gossypii), the appearance of the European tarnished plant bug Lygus rugulipennis, and biological control of caterpillars such as Chrysodeixis chalcites. An overview of the status of biological control in cucumbers in the Netherlands is given
