Abstract:
Leaf-mining Liriomyza spp. and their associated hymenopterous parasitoids were surveyed during the fall of 1980 and spring of 1981 on fresh market tomatoes in west-central Florida. L. sativae Blanchard was more abundant than L. trifolii (Burgess) in both seasons, accounting for 85.7 and 54.3% of the total reared in 1980 and 1981, respectively. The parasitoids Diglyphus intermedius (Girault), D. begini (Ashmead), and Neochrysocharis punctiventris (Crawford) were the most abundant larval parasitoids reared from leafminer-infested foliage, accounting for 28.8, 26.3, and 15.6%, respectively. D. begini was not detected in 1980, but was nearly as abundant as D. intermedius in 1981. Opius dissitus (Muesebeck) was the most abundant larval-pupal parasitoid reared from leafminer-infested foliage, accounting for 51.8 and 12.6% of the total parasitoids reared in 1980 and 1981, respectively.
