AbstractComparisons of three isomers of the San Jose scale [Quadraspidiotus perniciosus (Comstock)] pheromone showed that SJS3 was slightly more attractive than SJS1 or SJS2. Pheromone-baited traps were compared with sticky barrier traps for the detection and monitoring of male emergence activity and each trap type produced a different activity pattern relative to both calendar days and accumulated degree-days (DD). San Jose scale phenology varied between geographic areas of the Okanagan Valley when compared by using DD accumulations above either 7.2 or 10.5°C and suggests a trend towards decreasing DD requirements as the insect’s distribution moves north.

AbstractPhenological events associated with control of San Jose scale (Quadraspidiotus perniciosus (Comstock)) in deciduous tree fruit orchards of the western United States were modeled, using the Predictive Extension Timing Estimator (PETE). The model closely simulated adult male activity and first crawler emergence, although spring male emergence was too variable to rely entirely on accumulated degree days from 1 January for management decisions. Pheromone monitoring of spring males improves timing for control of subsequent crawlers when a biofix of 275°D from 1 January is used.

AbstractThe San Jose scale, Quadraspidiotus perniciosus (Comstock), was killed on harvested apples by fumigation with 32 g/m3 of methyl bromide for 2 hours followed by standard cold storage for about a month. Fumigation, without storage, did not kill all the scale.

AbstractThe habits of the San José scale, Aspidiotus perniciosus Comstock, and the European fruit scale, A. ostreaeformis Curtis, on harvested apples in British Columbia are discussed under the following topics: stages found on apples; distribution and mortality on apples; influence on size, odor, and skin of apples; discoloration of fruit; and appearance of scales on apples. Outstanding characteristics of the San José scale are: all stages occur on the fruit; crawlers settle primarily in the stem end of Newtown and Winesap apples, equally in the stem and calyx ends of Rome Beauty, and predominantly in the calyx end of Delicious; the scale survives longer in the stem end than in the calyx end of stored Newtown, Winesap, and Delicious apples; all scales eventually die in storage; and infestations decrease the size of apples, adversely affect color and maturity, impart a moldy odor to the fruit, and mark the skin of all varieties by causing red spots around the scales. Comparable habits of the European fruit scale are: males and females do not occur on the fruit; more crawlers settle in the stem end of Newtown, McIntosh, and Hyslop crab apples than in the calyx end but the reverse distribution occurs on Rome Beauty; the scale survives longer in the calyx end of all varieties; all scales do not die on apples placed in storage; infestations apparently do not affect size, color, maturity, and odor of fruit; and feeding of the scale seldom marks the skin of Newtown apples but it does cause purplish-red spots around the scales of all other varieties of apples.

AbstractPheromone trapping studies from 1979 to 1981 showed that there were two periods of San Jose scale, Quadraspidiotus perniciosus (Comstock), male flight activity annually in western New York apple orchards. Spring flight, which resulted from overwintering black caps, began at ca. 94–140 degree-days (base 10 °C from 1 March) and occurred during bloom in the apple varieties studied. First generation crawlers emerged at ca. 360 degree-days. Second generation crawlers emerged at ca. 890 degree-days and were active throughout September. Regression analyses showed a logistic relationship between crawler density and fruit infestation, and inverse linear relationships between pheromone trap catches and San Jose scale infestation levels within trees.
