The rearing of the honeydew moth,Cryptoblabes gnidiella Mill., is described. The toxicity at 27° and 22° C of diflubenzuron against eggs ofC. gnidiella was assayed by dipping in aqueous dilutions of a 5% liquid experimental formulation and of a 25% wettable powder (w.p.). The w.p. was more active than the liquid formulation, and toxicity at 27° was higher(More)
