“…Our findings on decreased adult longevity at 8 0 C for prolonging storage are pertinent with the study reported by Ozder (2004), where adult longevity of egg parasitoid T. cacoeciae was decreased after 31 days storage at 8 0 C. Rundel et al, (2004) exemplified the storage temperatures lower than 10 0 C and storage times 3 week or longer had a negative impact on longevity.…”

“…The lower the storage temperature resulted the higher the mortality in many studies. (Ballal et al, 1989;Venkatesan et al, 2000Rundle et al, 2004,Lopez & Botto, 2005Bernardo et al, 2008).…”

SummaryThe effects of cold storage on the biology of the larval parasitoid Venturia canescens were tested. Storage studies were conducted in two stages, pre-adult and adult stage of the larval parasitoid, Venturia canescens (Gravenhorst) (Hymenoptera: Ichneumonidae). Pre-adult stage of parasitoid was stored in last larval stage of the hosts, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) and Plodia interpunctella Hübner (Lepidoptera: Pyralidae) at 5, 10, 15°C for 1, 3, 5, 7, and 15 days. Similarly adult parasitoids were stored the same temperatures for honey feeding and non-feeding condition. Storage temperatures, Storage period and host effects on V. canescens development were evaluated. The parasitoid did not develop at 5°C for 5, 7 and 15 day storage period on both hosts. Similarly parasitoid did not develop at 10°C for 15 day storage period on the host P. interpunctella. Decreasing of temperature and increasing of storage time resulted in increasing in the parasitoid development time, but reducing emergence rate. This reduction of emergence rate was higher in P. interpunctella. Longevity and adult dry mass were less affected by low temperature in both hosts., the most suitable temperature for feeding and non-feeding condition on both hosts was found to be at 10°C for the adult. The results suggest that E. kuehniella could be more suitable host for V. canescens.

Depolama çalışmaları larva parazitoiti V. canescens'in ergin öncesi ve ergin döneminde gerçekleştirilmiştir. Parazitoitin ergin öncesi dönemi 5, 10, 15°C sıcaklıklarda ve 1, 3, 5, 7, 15 gün konukçuları Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) ve Plodia interpunctella Hübner (Lepidoptera: Pyralidae)'nın son larva dönemi içinde depolanmıştır. Benzer olarak ergin parazitoitler aynı sıcaklık derecelerinde besinli ve besinsiz koşullarda depolanmıştır. Çalışma sonucunda depolama sıcaklığı, depolama süresi ve konukçu farklılığının V. canescens'in gelişimini etkilediği belirlenmiştir. Parazitoitin iki konukçuda da 5°C'de 5, 7 ve 15 gün depolama sürelerinde gelişim göstermediği belirlenmiştir. Benzer olarak parazitoitin konukçu P. interpunctella üzerinde 10°C' de 15 gün depolanmasıyla da gelişim gösteremediği bulunmuştur. Depolama sıcaklığının düşmesi ve depolama süresinin artması parazitoitin gelişme süresini arttırırken, çıkış oranını azaltmıştır. Çıkış oranındaki azalma konukçu P. interpunctella üzerinde daha fazladır. Yaşam süresi ve ergin ağırlığı iki konukçuda da düşük sıcaklıkdan daha az etkilenmiştir. Ergin parazitoiter için hem besinli hem de besinsiz ortamda ve heriki konukçuda en uygun sıcaklık derecesinin 10°C olduğu belirlenmiştir. Sonuçlar, depolama çalışmalarında V. canescens için E. kuehniella'nın daha uygun bir konukçu olduğunu göstermektedir.

“…Increased longevity may be associated with reduced activity and metabolism at lower temperatures (Gerling 1972;Bleicher & Parra 1990). Suboptimal temperatures can shorten the lifespan (Jalali & Singh 1992;Torres et al 2002), reduce body size (Rundle et al 2004) and energy reserves (Renault et al 2003), increase the development period (Pratissoli et al 2004), and reduce emergence and fecundity of parasitoids (Colinet & Boivin 2011). However, the intensity of the response varies with natural enemy species (Lessard & Boivin 2013); for example, the parasitoid Bracon vulgaris Ashmead (Hymenoptera: Braconidae) showed 2-fold greater longevity at 20 °C than that at 25 and 30 °C (Wanderley et al 2007), and Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae) showed longevity of 34.4 and 1.5 d at 16 and 28 °C, respectively (Rodrigues et al 2013).…”
