This compound was essentially non-toxic to house flies by topical application but showed moderate activity against the green rice leafhopper and brown planthopper as a residual spray. These results raise the possibility of applying derivatization reactions for the synthesis of polymeric insecticidal materials which may act as slow release agents.

Thiadiazine insecticides are derivatives of thiadiazine. Buprofezin is the only current member of this group. It is an insecticide with persistent larvicidal activity against sucking insects such as mealybugs, rice planthoppers, scales, and whiteflies in rice, potatoes, citrus, cotton, and vegetables. Its oral LD50 in rats is 2198 mg/kg. 

Imidacloprid is a systemic insecticide with contact and stomach poison activity for control of sucking insects including aphids, leafhoppers, planthoppers, thrips, and whiteflies, and soil insects, termites, and some species of biting insects. It has an oral LD30 in rats of 450 mg/kg.

SAFETY PROFILE Poison by ingestion, intravenous, and intraperitoneal routes. Moderately toxic by skin contact. When heated to decomposition it emits toxic fumes of NOx. See also CARBAMATES. Used for controlling leafhoppers, planthoppers, and bugs in rice and cacao. 

Dimethoate is a systemic and contact insecticide-acaricide used on a range of insects including mites, flies, aphids, and planthoppers. Dimethoate is used very commonly in livestock for the control of botflies and mites. Formulations include aerosols, dusts, granules, and emulsifiable concentrates. 

Survey of insect populations in Florida established that Myndus crudus was by far the most abundant potential vector on coconut palms and the populations of this planthopper species were as much as 40 time higher in areas of high Coconut Lethal yellowing incidence than in disease free areas (Howard, 1980).
