Response of Liriomyza (Diptera: Agromyzidae) and its Parasites to Stake and Mulch Culture of Tomatoes
Abstract
The influence of tomato cultural systems, mulching and staking, on the leafminer, Liriomyza sativae Blanchard (= L. munda Frick) and its parasites was evaluated in 1973 in 1 spring and 2 fall field experiments at Bradenton, Florida. Leaf samples were examined for leafmines, and field collected pupae were held for parasite emergence. Both cultural techniques had a positive influence on Liriomyza and parasites. The number of leaf mines in tomato foliage from mulch culture and from stake culture was increased in the spring experiment but the same was true for only stake culture in the fall. Parasitism of leafminers by Opius spp. (Braconidae) was reduced by stake culture.Downloads
