Alternating temperatures affect the performance of Trichogramma species.
Bottom Line: Fecundity and longevity of parasitoids were significantly reduced under high temperature shocks to egg-laying females.However, the effect was more severe in eggs.Overall, daily short-term temperature shocks to different developmental stages of parasitoids showed radical effects on emergence, fecundity, longevity, and sex ratio of the progeny.

Mentions: Adult emergence of parasitoids (G0). Adult emergence of T. poliae and T. chilonis was also significantly affected (F = 1148.24, P < 0.01, df = 5, and F = 934.58, P < 0.01, df = 5, respectively) as a result of daily short-term exposure to higher temperatures (Figure 2). Furthermore, adult emergence was significant ly affected when egg-stage T. poliae (F = 1682.17, P < 0.01, df = 2) and T. chilonis (F = 1600, P < 0.01, df = 2) were exposed. Significant differences were also noticed between different temperature shocks and life stages of T. poliae (F = 360.77, P < 0.01, df = 10) and T. chilonis (F = 251.51, P < 0.01, df = 10).
