Problems solved by technology

However, in the optimum temperature range, the development rate is directly proportional to the temperature. However, when the temperature exceeds the optimum temperature, the development rate can continue to increase, but the ability of natural enemies to feed, parasitize / prey, etc. decreases, which affects the expansion of natural enemies. increase the cost of rapid multiplication of natural enemies, and hinder the progress of natural enemy biological defense projects

Embodiment 1

[0024] Example 1 Artificial large-scale rearing of the Aphididae wasp

[0025] (1) Basic facilities

[0026] Insect breeding room: 4 rooms are required, which are respectively used for the cultivation of clean cotton seedlings, the breeding of whitefly populations, the maintenance of parasitic bee populations, and the rapid expansion of parasitic bees. The area depends on the scale of breeding, generally 10 to 20m 2 It is advisable that if the demand for parasitic bees is large, the number of insect culture rooms can be increased. The windows are equipped with stainless steel screens, and an exhaust fan is installed for ventilation and a 1.5 hp intelligent inverter air conditioner to control the temperature in the insect breeding room; different numbers of layered insect racks are placed in the insect breeding room according to the actual area size, and are controlled by KG316T microcomputer The control switch automatically controls the switching time of the light tubes on al...

Embodiment 2

[0049] Example 2 Changing the temperature of parasitoid nymph development and adult oviposition period improves the large-scale propagation rate of parasitoids

[0050] Parasitic wasps can generally be divided into pre-adult stage and adult stage, and pre-adult stage generally includes egg stage, nymph stage and pupal stage. In the early adult stage, the individual development of the parasitic wasp is mainly completed, and it has no ability to control the host; the adult stage mainly controls the host through feeding, parasitism and direct death. The ability of a parasitoid to control the host is generally reflected by its intrinsic growth rate (r), and the intrinsic growth rate mainly depends on the length of the parasitoid's pre-adult stage and the fecundity of the adult stage. Temperature can change the developmental rate of parasitoids and also affect their fecundity and feeding ability. Therefore, how to improve the pest control ability of parasitoids by changing the tem...

Abstract

The invention relates to a natural enemy insect rapid propagation technology, and particularly relates to the method for propagating haematopus aphid wasps rapidly by using temperature transition. The method comprises the steps of cultivating a host plant cotton; feeding haematopus aphid wasps with bemisia tabaci, wherein the best temperature for the growth of the haematopus aphid wasps imago at an early stage is 30 DEG C; and the oviposition temperature at the imago stage is 26 DEG C; the darkness suitable for lighting L:D=14:10; and the suitable humidity is 60-80%. The artificial haematopus aphid wasps breeding method is used to accelerate the parasitic wasps' breeding rate while raising breeding temperature without reducing the parasitic wasps' breeding efficiency, therefore, the method is especially convenient for breeding the parasitic wasps indoor in large scale, and the wasps can be propagated rapidly.

Description

technical field [0001] The invention relates to a method for raising local parasitic natural enemy insects, in particular to a method for rapidly multiplying the wasps of O. haideni by using temperature conversion. Background technique [0002] Bemisia tabaci (Gennadius), also known as cotton whitefly or sweet potato whitefly, belongs to Hemiptera Hemiptera whitefly family Aleyrodidae, small whitefly, is a small piercing-sucking insect that feeds on the phloem of herbaceous plants . Due to the rapid development of resistance, Bemisia tabaci has become a major pest of cotton, vegetables and ornamental plants in many countries. In recent years, it is more and more inclined to use biological control as the mainstay, combined with other control measures to carry out sustainable comprehensive control of Bemisia tabaci. [0003] The wasp Eretmocerus hayati (Zolnerowich and Rose) not only can parasitize but also can directly feed on the nymphs of Bemisia tabaci, showing a strong ...
