Embodiment 1
[0012] Embodiment 1: Taking 1,000,000 Trichogramma corn borer as an example on July 10 this year, the method of breeding diapause Trichogramma corn borer is as follows:
[0013] 1. Breeding bees: First, on January 30, a sufficient amount of wheat moth eggs and seed bees (40g wheat moth eggs, 100,000 Trichogramma corn borer seed bees) were connected to the breeding beehive, and the temperature of the breeding beehive was controlled at The temperature is between 20-28°C, and the relative humidity is controlled between 70%-90%.
[0014] 2. Induce the diapause of Trichogramma corn borer: 24 hours after receiving the bees, blow off the seed bees, collect the eggs of the wheat moth and put them in the breeding room to continue to develop. On the third day after receiving the bees (about 50 hours after receiving the bees), put the Trichogramma bee into a shallow open bottle, seal it with a black cloth, and then transfer it to a controlled temperature of 10.5-12.5°C and a humidity of ...
Embodiment 2
[0017] Example 2: The basic conditions and steps of the constant temperature induced Trichogramma corn borer diapause storage method are the same as in Example 1, wherein the storage conditions of the induced diapause Trichogramma is a temperature of 3-5 °C, and the storage time is 5 months . The conditions for the long-term storage of Trichogramma to recover and develop are as follows: temperature 28°C, humidity 90%, photoperiod 14L:10D.
