Method for simultaneously improving bee output rate and female quantity of indoor bred cotton bollworm odontolimus

Abstract

The invention belongs to the field of parasitic wasp breeding in biological control, and relates to cotton bollworm odontolimus, in particular to a method for simultaneously improving the bee output rate and the female number of cotton bollworm odontolimus bred indoors. In the method, the used medicament is ciclosporin A, the molecular formula of the ciclosporin A is C62H111N11O12, and the relative molecular mass of the ciclosporin A is 1202.61. According to the method, the bee emergence rate and the number of female insects after cotton bollworm parasitism of the cotton bollworm are increased by feeding the cotton bollworm cyclosporine A, the cotton bollworm parasitism of the cotton bollworm is fed with the cyclosporine A to reach the first day of three years old, the bee emergence rate of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism of the cotton bollworm parasitism The inventor finds that after cotton bollworms eat cyclosporine A, the bee emergence rate and the female insect number of the cotton bollworm and the odontolimus of the inner body of the cotton bollworm and the odontolimus of the cotton bollworm can be remarkably increased, and the method has important significance on breeding and biological control of the cotton bollworm and the odontolimus of the cotton bollworm.

Description

technical field [0001] The invention belongs to the field of parasitic wasp breeding in biological control, relates to the cotton bollworm Adenophora, in particular to a method for simultaneously increasing the emergence rate and the number of females of the cotton bollworm in indoor breeding. Background technique [0002] Lepidoptera insects are important agricultural and forestry pests distributed worldwide. Their feeding habits are complex, and they harm more than 300 kinds of plants such as cotton, corn, vegetables, honeysuckle, ginkgo, poplar, paulownia, and fruit tree seedlings. Agricultural use of Bacillus thuringiensis ( Bacillus thuringiensis , Bt) crops to control Lepidoptera pests such as cotton bollworm, but the level of pest resistance is increasing. In addition, in the past ten years, my country's crop planting structure has undergone major adjustments, and the planting area of ​​transgenic cotton in the Yellow River Basin and the Yangtze River Basin has dropp...

Problems solved by technology

However, larvae at the end of the 2nd instar complete the difficult molt and enter the 3rd instar, and there will be a certain rate of death

In addition, when the cotton bollworm parasitized the end of the second instar cotton bollworm, even in the most suitable mating mode, although the emergence rate of the offspring would increase, the eclosion rate was low, and the final bee emergence rate It is also below 47%, and the offspring are more male

At the same time, in an environment where there has been parasitism, when the cotton bollworm parasitizes the 2nd instar cotton bollworm, the rate of bee emergence can be as high as about 60% under careful breeding, but among the bees that emerge, most of the bees are males, and females are mostly males. Rarely, it is difficult to meet the control requirements and the breeding needs of offspring
