Effective dose present in cockroach larvae exposed continuously to a juvenile hormone active insect growth regulator

Management of a German cockroach population with a juvenoid bait formulation: computer simulation

“…Juvenoids are, in essence, slow-acting insecticides, which must be present at a certain concentration in the insect's body during a sensitive period in order to affect the insect development. The amount of juvenoid present in the insect is the result of dynamic relationship between intake, metabolism, and discharge of the substance (Masner et al, 1979). A simple one-compartment model of the accumulation and depletion type was adopted (Paterson, 1979):…”

Effects of hydroprene on development and reproduction in the Oriental cockroach, Blatta orientalis

“…These compounds have very low mammalian toxicity which, combined with their specificity to insects and other arthropods, makes them suitable candidates for use in the domestic environment and in food manufacturing or handling areas. Das & Gupta (1974), Riddiford et al (1975), Masner et al (1978) and others demonstrated the effects of these eompounds on cockroaches and showed that they could have potential as control agents. More recently, studies in the United States have demonstrated the practical efficacy of two JHAs, hydroprene and fenoxycarb, in practical control programmes against the German cockroach B.germanica (Staal et at., 1985;Bennett et al, 1986;Brenner et al, 1988).…”
