When analyzing the insects, the temperature and humidity have an impact on the production of pests?

    The climatic conditions have a very close relationship with the development of insects. Temperature and humidity have a direct impact on the growth, survival and reproduction of pests, which leads to different occurrences, occurrences and damage levels of pests. It can also affect the occurrence of pests through the benefits of host plants or natural enemies. Therefore, when analyzing the insect situation, temperature and humidity are two fairly important indicators, and the comprehensive ability of temperature and humidity has a great influence on the variation of insect population. Generally, the seasonal temperature and humidity have a comprehensive impact on insects. The ability can be summarized as follows:

    1. In the autumn and winter season, when the insects are ready for winter or just entering the winter period, the water content in the pests is relatively high under high temperature and high humidity, and the supercooling point is also high, causing the cold resistance of the pests to weaken and the winter to die. More. However, after entering the winter, the humidity is often very favorable for maintaining the water balance, and it is also beneficial to the spring.

    Second, the temperature is relatively low and dry in autumn and winter, the water content of the pest is relatively low, the supercooling point is also very low, has a strong cold tolerance, and the mortality rate in winter will be less.

    Third, the spring worm has been released from dormancy or diapause. If the temperature is warmer and there is more spring rain, the metabolism of the pest will become faster, and the water content of the worm will increase. If it encounters the cold current, it will change its cold resistance. Weak, causing increased insect deaths.

    Fourth, the summer is usually at high temperature. If it encounters high humidity, the water in the larvae of the pests will evaporate slowly, the body temperature is higher, the metabolism is faster, the developmental period is shorter, the life span of the adult is usually longer, and the total reproduction is relatively large. . However, if it is not a good wet insect, it is also very hot and dead.
