Abstract:
The susceptibility of larvae of Thaumetopoea solitaria Freyer (Lepidoptera; Notodontidae; Thaumetopoeinae), fed on treated pistachio foliage, to three commercial control products derived from Bacillus thuringiensis (Bt), was evaluated in the laboratory. Both Dipel DF and Delfin WG were highly effective against 1st and 2nd instar larvae at relatively low concentrations (LC50: 0.01-0.04%), whereas mortality of the 3 rd instar larvae reached 50% only at a Dipel DF concentration of 0.2%. The third formulation, Foray 48B, was significantly less toxic toward all tested larval instars. The susceptibility of T. solitaria to Bt decreased progressively between molts, and then increased steeply during the first days following each molt. Use of the film-forming polymer Nu-Film as a wetting agent and spreader-sticker for the commercial formulation of Dipel DF improved Bt adhesion to extremely hydrophobic young Pistacia foliage, and significantly increased Bt persistence under ambient conditions. Addition of Nu-Film improved the leaf surface coverage and extended the duration of rain-proofing.
