What is Environmental, cultural and insecticidal effects on the vegetable leafminer, Liriomyza sativae Blanchard, and its parasites about?

The vegetable leafminer, Liriomyza sativae Blanchard (Diptera: Agromyzidae), has been a serious pest of Florida's tomato and celery industry since 19 72. Leafminer populations were studied on commercial vegetable farms in two areas of Florida. Initial research focused on celery and tomato transplant seedlings grown in plant production ranges in Sun City, Florida, during the fall and winter of 1977 and 1978 (October to March) . In the spring and summer of 1978 (March to July) the research was conducted on commercial celery farms in Belle Glade, Florida, and complementary laboratory experiments were conducted in Gainesville, Florida. Adult leafminer invasion of the transplant production farm, monitored with yellow cardboard traps covered by sticky, transparent plastic, was the result of prevailing winds over nearby tomato fields. Ratio of larval mines to stipples was related to adult leafminer preference for host seedlings. Leafminer host preference was influenced by prior host developmental association, by host cultivar and species and seedling age. The number of adult leafminers and parasites reared from celery leaf samples was influenced by temperature, humidity and the number of
