The Mean

Effects of constant temperatures of 10, 15, 20, 25, 30 and 35°C on the preoviposition period and the effects of a constant 25°C on oviposition, fecundity, and longevity of the redbanded leafroller, Argyrotaenia velutinana (Walker), and the tufted apple bud moth, Platynota idaeusalis (Walker), were investigated. Oviposition did not occur at 35°C for either species and only the redbanded leafroller oviposited at 10°C. The threshold for oviposition for RBLR was calculated to be 8.7°C with 29.4 DD necessary for oviposition, while the oviposition threshold for TABM was calculated to be 10.5°C with 33.5 DD needed for oviposition. The mean oviposition periods for the two species did not differ; however, tufted apple bud moth longevity was significantly greater at 25°C. Fecundity was greater for the tufted apple bud moth (301 eggs/female) than for the redbanded leafroller (221 eggs/female).

Adult Exposure

The tufted apple bud moth, Platynota idaeusalis Walker, is a major pest of apples in the eastern United States. Resistance to conventional insecticide chemistries has made this pest difficult to control. The insect growth regulators (IGRs) tebufenozide and methoxyfenozide, which are target-specific to lepidopteran pests, have been shown to have high efficacy against P. idaeusalis larvae. These compounds are known to affect adult moths in related tortricid species, but the effects of exposure on adult P. idaeusalis are unknown. This study investigated the effects of adult exposure on the fecundity and fertility of P. idaeusalis. Both tebufenozide and methoxyfenozide significantly reduced the fecundity and fertility of female P. idaeusalis adults that were exposed to dry films of formulated IGR residue. Female fecundity and fertility also were reduced when untreated or treated females mated with treated males. Contrary to other related studies, there was no difference in fecundity/fertility reduction efficacy between tebufenozide and methoxyfenozide. Thus, because tebufenozide and methoxyfenozide have reproductive activity against adults, such compounds may bring significant benefits to integrated pest management (IPM) of tree fruits.

Egg Mass Size

Intensive sampling was used to characterize the size and leaf type for tufted apple bud moth, Platynota idaeusalis (Walker), egg mass deposition, and to determine the association and site of larval feeding on fruit and foliage in Pennsylvania apple orchards. Results suggest tufted apple bud moth prefer to oviposit on smaller leaves (<20 cm2), and egg mass size was 0.16 cm2 during first brood and 0.12 cm2 during second brood. Significantly more first and second brood egg masses were oviposited on leaves within nonfruiting spurs than on either vegetative shoots or fruiting spurs. Both larval broods were found in association with leaves only rather than leaves and fruit. Fruit injury due to larval feeding during both broods occurred more on the calyx (sepals) surface area than the side or stem surface areas of the fruit. In cultivar comparisons of fruit, more surface injury was located on the site of the fruit from ‘Stayman’ trees than for ‘Golden Delicious’ trees.
