Monitoring Mass Rearing of the Codling Moth12

Effect of Temperature on the Oviposition, Longevity and Mating of Codling Moth,Cydia pomonella(L.) (Lepidoptera: Tortricidae)

“…Where fecundity has been found to vary between and within seasons this variation has been attributed to variations in climatic factors, such as either unfavourable temperatures (Isely 1938: Geier 1963: Wearing & Ferguson 1971 or snowfall (Trottier & Hagley 1979), rather than food quality which has also been cited as a reason for variation in fecundity (Wearing & Ferguson 1971). Deseö (1971) found a positive correlation between adult weight and fecundity, while Hathaway et al (1973) found no relationship between pupal weight and fecundity. Geier (1963) reported a significant difference between the mean body weights of the Summer 37 Trottier & Hagley (1979) Ontario, Canada Spring 9.7-32.9 *From Geier (1963), Ferro et al (1975) and Howell (1991).…”

“…Many of the studies on longevity and oviposition have been undertaken with laboratory colonies that may differ from field populations due to adaptation to laboratory conditions and rearing procedures (Proverbs & Newton 1962;Deseö 1971;Hagley 1972;Hathaway et al 1973;Howell 1981). Consequently, there are inconsistencies in relating laboratory observations to field observations (Geier & Briese 1978).…”

Improved quality management to enhance the efficacy of the sterile insect technique for lepidopteran pests

“…Assessment of sterile male quality has been exercised primarily in the massrearing facility, and most advances have been made on quality control of mass-reared tephritid fruit flies ((FAO/IAEA/USDA) Food and Agriculture Organization of the United Nations/International Atomic Energy Agency/United States Department of Agriculture 2003; Calkins and Parker 2005;(IOBC 2007) Arthropod Mass Rearing and Quality Control 2007). Quality control in rearing moths has not been emphasized to the same extent, even though many workers have reported on various quality parameters (Hathaway et al 1973;Rogers and Winks 1993;Bloem et al 1997Bloem et al , 2004Vreysen and Hendrichs 2005). Although the need to link sterile insect quality to field performance is well established (Leppla and Ashley 1989;Lux 1991;Leppla 1993), limited attention has been given to routine assessments of the performance and competitiveness of released sterile insects in the field (Vreysen 2005).…”

Effect of Cold Treatment on Survival and Development of Codling Moth (Lepidoptera: Tortricidae) in Cherry

“…There was no signiÞ-cant difference in adult emergence between organic and conventionally grown cherries for each of the cold storage regimes (t ϭ 0.30, df ϭ 6, P Ͼ 0.05). In comparison, 28.6% of larvae emerged as adults in mass rearing (Hathaway et al 1973) and 48% of larvae emerge as adults from immature apples (Hathaway et al 1971).…”
