“…It would have been ideal to have included a fifth plot within each block untreated in any manner for control of apple maggot. To have done so, however, could have severely jeopardized marketability of the fruit, as the apple maggot can rapidly colonize and substantially damage unprotected fruit ( Glass and Lienk , 1971).…”

We evaluated three different deployment patterns of sticky red sphere traps, baited with a five‐component blend of synthetic attractive fruit odour and placed on perimeter apple trees bordering adjacent habitat (front‐row trees), for control of apple maggot flies, Rhagoletis pomonella (Walsh), in small plots of apple trees (about 30 × 30 m) in Massachusetts commercial apple orchards. Degree of fly penetration from front‐row to interior apple trees was assessed for R. pomonella of wild origin and for marked adults released in habitats adjacent to front‐row trees. Traps placed 10 and 5 m apart on front‐row trees or grouped on a single central front‐row tree performed as well as grower‐applied insecticide sprays in preventing penetration of plots by wild and released flies and in preventing fruit injury. This was equally true for plots whose front‐row trees consisted of cultivars comparatively susceptible to apple maggot as for plots whose front‐row trees were comprised of comparatively tolerant cultivars. It was also true for each seasonal period during which sampling for treatment performance occurred.

“…From 1977From to 1989 by this insect at harvest was usually below 1% in Québec commercial apple orchards, whereas damage in unsprayed orchards varied between 6 and 85% (Vincent and Roy 1992). Within 1-3 yr after cessation of pesticide spraying, plum curculio populations invariably return to levelsof économie importance (Glass and Lienk 1971;Hagley étal. 1977;Hall 1974).…”

Plum curculio (Conotrachelus nenuphar) is a native pest of pome and stone fruit in eastern North America. It is a key pest of apple (Malus pumila) orchards in Quebec. In spring, adults disperse primarily from woodland overwintering sites to apple orchards. Before fruit set, the beetles are mainly nocturnal. As fruits become available for oviposition, adults extend their activity to the daytime. Full grown larvae found in dropped apples in June (June drop) enter the soil to pupate. The summer brood emerges in August, feeds on the remaining fruit throughout the fall and then disperses to suitable overwintering sites. Little is known of its community and host plant relationships, dispersal behavior, factors influencing its mode of locomotion, choice of food sources, overwintering sites, micro-habitat selection, orientation, and action threshold. Commercially available biocontrol agents are not effective, and convenient and reliable monitoring techniques for the timing of sprays have not been developed. However, recent field and insectary studies on the behavior and activity of plum curculio adults may allow us to improve the efficiency of control strategies. These findings are presented here, together with their implications for control of the plum curculio by modifying its habitat, and by better timing and location of sprays and other interventions. This paper also includes brief reviews of biological controls, insect growth regulators, and genetic controls for plum curculio.

“…Often insect injury is a direct result of residual insects from the preceding season on or in ripe and rotten fruits on the ground or on the tree (Glass et a/., 1971). Poor sanitary conditions in orchards are common in Afghanistan, and are partly responsible for pest attack.…”

A study in three different ecological zones: the Paghman valley, Kabul Plateau; the Afghan-Turkistan; and the Southwestern region, was conducted over two years to learn more about the impact of the major arthropod pests on the quality and quantity of the deciduous fruits in Afghanistan. Eight major pests were found to be causing considerable damage: Codling moth, Cydia pomonella (L.) and lesser ermine moth, Yponomauta padella (L.) were the limiting factors in the production of apple and almond respectively in some areas. Aphis pomi Degeer, Eriosoma lanigerum (Hausmann) and San Jose scale Quadraspidiotus pernidosus (Comstock) were more serious in the Southwestern region than the other areas. The mites, Tetranychus urticae (Koch) and Panonychus ulmi (Koch) were more serious in the Afghan-Turkistan region. Rhagoletis pomonella (Walsh) was not as serious as codling moth.
