AbstractUC-62644, a moult-inhibiting insect growth regulator (IGR) belonging to the benzoylphenylureas, had an EC50 of 0.1 to 0.2 ppm in a meridic diet for the 3rd to 6th larval instars of the spruce budworm, Choristoneura fumiferana Clemens. The effects of the IGR were apparent in less than 48 h after ingestion and there was evidence for some contact toxicity. The larvae were unable to discriminate between IGR-treated and untreated diet. Experimental aerial application of the IGR revealed that at <70 g in 4.7 1/ha (1 oz in 0.5 U.S. gal/acre) it effectively controlled spruce budworm populations and afforded foliage protection. These results were comparable with those obtained with Matacil® applied at the recommended rate.

Experimental Tool

Embryonic development of the hemipteran Rhodnius prolixus is perturbed by fenoxycarb (Ro 13.5223, Dr. R. Maag Ltd.), a non-neurotoxic insect growth regulator. Degree of perturbation is dependent on dose applied and embryonic stage at application time. Day 5 embryos were the most sensitive over a broad dose range. Treatment on day 8 had little effect, with normal hatching occurring 1 week later. Three developmental stages were most sensitive to perturbation: katatrepsis, dorsal closure, and eclosion. Katatrepsis, which normally occurs 168 h postoviposition, was the stage most prominently affected, suggesting that fenoxycarb interferes with basic mechanisms underlying this morphogenetic movement. Dorsal closure was the second most sensistive stage, the defect being characterized by embryos failing to completely enclose the yolk. Embryos receiving very low doses successfully completed katatrepsis and dorsal closure but were unable to hatch. Results demonstrate that fenozycarb may be a useful experimental tool for examining the normal cellular mechanisms of insect embryogenesis.
