HORTICULTURE

Detailed explanation-1: -Insects such as stoneflies, mayflies, caddisflies, and dragonflies are common overwintering aquatic insects. The dance fly larvae have the lowest reported supercooling point for an aquatic insect at −22 °C.

Detailed explanation-2: -Insects assume an internal body temperature similar to their environment, leaving them vulnerable to harsh winter weather and fluctuating temperature regimes. Most insects do not develop or function at temperatures below 50°F, but they do not typically freeze until temperatures are well below-4°F during overwintering.

Detailed explanation-3: -Insect pests usually develop in the temperature range between 15º and 35ºC.

Detailed explanation-4: -The optimum temperature for maximum insect development is 75°-90°F; if magnified by moisture, microbial growth can be accelerated. One approach for managing insects is to create an environment outside this optimum temperature zone of survival and reproduction: 120°-140°F: insects die in minutes.
