Effects of short-term heat shock and physiological responses to heat stress in two Bradysia adults, Bradysia odoriphaga and Bradysia difformis.

摘要: Bradysia odoriphaga and difformis are devastating pests of vegetable, ornamental crops edible mushrooms causing significant losses. Temperature may be an important factor restricting their population abundance in the summer. To determine effects short-term heat shock on adults, survival, longevity fecundity data were collected, antioxidant responses protein expression levels examined. Our results indicated that survival rates adults decreased rapidly after ≥36 °C, reproductive capacities significantly inhibited, indicating had lethal sub-lethal effects. Moreover, lipid peroxidation B. increased dramatically at 36 °C 38 °C, respectively. Four enzymes activities greater than those 38 °C. Additionally, hsp70 hsp90 stress, higher discovered 36 38 °C respectively, different tolerance levels. Overall, (≥36 °C) caused adverse it could applied pest control, system hsp genes played roles
