“…The results, which show that fenoxycarb is highly active, particularly when two sprays are applied, are consistent with the findings of many previous workers (e.g. Schmid et al, 1978;Shooneveld, Van der Molen & Wieberga, 1976;De Reede, Groendijk & Wit, 1984;Blommers & Trapman, 198.5). Fenoxycarb is used to virtually eradicate the overwintered caterpillars which, after exposure, fail to pupate or to successfully emerge from pupation (Abdullah, 1972;Schooneveld & Abdullah, 1975).…”

The susceptibility of populations of the summer fruit tortrix moth, Adoxophyes orana, from apple orchards in Kent, England, to chlorpyrifos was determined in 1992, 1994 and 1995, by topically dosing larvae feeding on leaves or adults adhered to pheromone trap sticky bases. LD50 values (range 6.3 to 23.2ng chlorpyrifos per individual) for first or second generation males, second generation females or for first generation fourth instar larvae collected in the field were significantly greater (2-3 fold) for populations from orchards with a long history of treatment with broad-spectrum organophosphorus and other insecticides than for those from untreated orchards (range 1.6 to 8.1 ng chlorpyrifos per individual), though there was considerable variation between sites and years.Twelve replicated orchard experiments between 1993 and 1995 were used to examine a range of different strategies for insecticidal control. Applications of chlorpyrifos against overwintered larvae feeding in trusses in spring gave, at best, a 75% reduction in larval numbers, insufficient to prevent damage by the subsequent generation in summer. However, two applications of fenoxycarb (one immediately pre-and one immediately post-blossom of apple cv. Cox) completely prevented successful subsequent development of the pest, and a single (postblossom) spray nearly so.The timing of application of chlorpyrifos against first generation larvae hatching from eggs in June was shown to be critical and currently used methods of spraytiming were unreliable. The effective persistence of chlorpyrifos was short ( < 7 days). Though good control could be achieved with a single spray, a better strategy was to apply a series of sprays at 7-day intervals to cover the egg hatch period. Sprays of Bacillus thuringiensis at the same timing intervals gave, maximally, an 80% reduction in larval numbers, but usually less: improved control was not achieved by applying a programme of sprays compared to a single spray, though a novel, more potent, formulation was significantly more active. Triazophos was also effective as an egg hatch spray. Sprays of chlorpyrifos or tebufenozide between late September and mid-October 1995 against second or third instar larvae migrating to overwintering sites before diapause, failed to reduce significantly the numbers of subsequent overwintering larvae or the numbers that emerged to feed on blossom trusses in spring.

“…These results are in contradiction with previous observations in small scale field experiments, in which A. orana and P. heparana were susceptible to epofenonane (de Reede et al, 1984). The effectivity of epofenonane and a related compound in reducing the population of A. orana was shown in experiments in several commercial orchards (Schmid et al, 1978;Charmillot et al, 1983). Immigration of moths from adjacent IPM-O and IPM-DIM plots during summer may have blurred any original effect in our experiments.…”

Three selective insecticides for leafroller control were evaluated as part of research efforts for refinement of Integrated Pest Management (IPM) in apple orchards in the Netherlands. Population levels, injury to fruits and degree of parasitism of leafrollers were studied in 0.5–1 ha plots of an experimental orchard. Plots were sprayed during 5 consecutive years with either Dimilin® (diflubenzuron, a chitine synthesis inhibitor), a strain of Bacillus thuringiensis or epofenonane, a juvenile hormone analogue. Dipel and Dimilin were not sufficiently effective in reducing population levels and degree of fruit injury. Hard to control pests in Dipel‐treated plots were especially Pandemis heparana, Spilonota ocellana and Laspeyresia pomonella and in Dimilin treated plots P. heparana and Adoxophyes orana. Epofenonane could not be evaluated properly because of interference by immigration of moths from nearby untreated plots. RÉSUMÉ Contrôle intégré avec Bacillus thuringiensis, diflubenzuron et épophénonane des tordeuses de pommier aux Pays‐bas L'étude a porté sur la protection, par 3 insecticides sélectifs, de vergers attaqués par des tordeuses. Ce travail constitue une part des travaux menés aux Pays‐bas pour améliorer la lutte intégrée dans les vergers. Nous avons étudié les niveaux des populations de tordeuses, leurs dégâts sur fruits, ainsi que les taux de parasitisme, dans un verger expérimental divisé en parcelles de 0,5 à I ha. Pendant 5 années consécutives, les différentes parcelles ont subi des pulvérisations de Dimiline (diflubenzuron), inhibiteur de la synthèse de chitine, de Dipel (B. thuringiensis), et enfin d'épophénonane, un analogue de l'hormone juvénile. Le Dipel et la Dimiline ont présenté peu d'efficacité dans la réduction des populations et du niveau des dégâts. Les insectes particulièrement difficiles à contrôler sont, respectivement, dans les vergers traités par le Dipel: Pandemis heparana (Denn. et Schiff.), Spilonota ocellana (F.) et Laspeyresia pomonella (L.), et dans ceux traites par la Dimiline: P. heparana et Adoxophyes orana (F.v.R). Nous n'avons pas pu évaluer l'effet de l'épophénonane d'une fâçon satisfaisante, en raison des réinfestations par des papillons venant de terrains voisins hébergeant des populations élevées de tordeuses.

“…Juvenoids often affect reproduction. Juvenile hormone analogues applied at the immature stages reduce the offspring production by affecting females during their adulthood both in stored‐product insects40, 41 and in non‐stored‐product insects 42–46. Furthermore, JH in the male larva affects spermatogenesis during the adult stage 47.…”
