Abstract
Applied as a soil drench to chrysanthemums, 0.4% crude neem extract caused significant mortality of late instars and pupae of Liriomyza trifolii (Burgess) in both research and commercial greenhouses. Insecticidal effects of drenching lasted for 3 weeks. Drenching did not inhibit female feeding or oviposition. Repeated drenching did not significantly inhibit plant growth. Mortality (89%) of prepupae reared from untreated plants occurred when the prepupae were placed on neem-drenched soil.Keywords
