Catalpa Sphinx: Formulations of carbaryl, chlorpyrifos (Dursban 50W only), cryolite, cyfluthrin, cyfluthrin and imidacloprid, deltamethrin, lambda-cyhalothrin, pyrethrins and piperonyl butoxide, spinosad, and tau-fluvalinate are labeled for the management of catalpa sphinx infestations.
Management Hints: The larval stage of this insect feeds gregariously (in groups). Mature larvae are about 50 to 65 millimeters long. Larvae are often parasitized by a small
wasp whose successful attack is indicated by the presence of small, white cocoons on the outside of the caterpillar’s body. Direct sprays against infestations of this pest when larvae are present from mid-May through September.
White Peach Scale: Formulations of acephate, azadirachtin (Ornazin 3% EC only), buprofezin, carbaryl, chlorpyrifos (Dursban 50W only), cyfluthrin, cyfluthrin and imidacloprid, deltamethrin, dinotefuran, horticultural oil, hydrophobic extract of neem oil, insecticidal soap, lambda-cyhalothrin (Battle GC, Demand CS, Scimitar CS, Scimitar GC, and Scimitar WP only), and methidathion are labeled for crawler management.
Management Hints: Treat when crawlers are first present in late May or early June. A second generation occurs from late July through early August. (p. 392)
