In a wide-ranging survey O'f 11 bla'::kcurrant blDcks. mortality of currant clearwing. Synanthedon salmachus (L.), was found to rang:e from 1.3'7c to 9.7% for larvae and from 5.3% to' 23.0% for pupae. At least 51'7c Df the mortality was caused by the fungal pathogens Beauveria bassiana, Paecilomyces f'arinosus, and Verticillium lecanii. One unidentified predatory carabid larvae was cO'llected. and twO' parasites-Xanthocryptus novozealandicus and Diadegma sp.-were reared from clearwing larvae.
Dry heat is proposed as a non-chemical postharvest disinfestation treatment for export persimmons (Diospyros leaki L.). A fruit surface temperature of 47°C at 55-60% RH for 15 min is recommended to effect 100% mortality of thrips, mealybugs, and leafrollers. On persimmon fruit these are all surface dwelling pests. Fruit tolerance trials showed that this fruit surface temperature/time exposure was not detrimental to persimmon fruit firmness, soluble solids concentration, and appearance; and did not reduce shelf life. A commercial scale confirmatory trial is planned.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
