- Abstract
In this study, the effect of exposing the adult stages of the predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) to cold temperatures at different times was examined. In the experiments, individuals that reached the adult stage on the same day were kept in the dark for 5, 10, and 15 days at 7, 10, and 15°C. Adults kept at low temperatures were fed three times per week with Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs and honey water. Individuals of N. tenuis that survived after cold exposure were reared at 25°C under a 16:8 (L:D) day-night cycle. The lowest adult survival rate after cold exposure was 65.00% when held at 7°C for 15 days. The highest survival rates were 94.00% and 98.00% when stored at 7 and 10°C, respectively, for 5 days. The most extended longevity in individuals reared following cold exposure was 14.06 days at 7°C and 14.94 days at 10°C, respectively, while the shortest lifespan was 8.10 days in adults held at 15°C for 15 days. The average number of nymphs produced by adults kept at 7°C for 15 days was 322.4, while the number produced by adults kept at 15°C for 15 days was 47.6. Except for the nymphs acquired from adults held at 15°C for 15 days, the number of nymphs obtained from adults stored at other temperatures and durations did not differ statistically from the control group. The study concludes that those who intend to mass-produce N. tenuis adults should store them at temperatures between 7 and 10°C for up to 10 days.
