Embodiment Construction

[0022] The specific steps of the method for breeding and raising Aphidius persicae in this embodiment are completely the same as those described in the Summary of the Invention.

[0023] The method for breeding and raising Aphids persicae in small floating seedling sheds of the present invention is carried out in Jietou Ginkgo persicae breeding base in Tengchong County, Baoshan City, Yunnan Province and in Longyang District, Bingmasia persicae breeding base. The Bingma Breeding Base in Longyang District is 1,600 meters above sea level, and the tobacco variety is K326. Utilize the existing floating seedling sheds that have completed the cultivation of tobacco seedlings, carry out disinfection treatment, sow a batch of tobacco seedlings on April 30, and more than 90% of the tobacco seedlings will reach 3 leaves and 1 heart on May 23, and use the seedlings for expansion and reproduction. The aphids were inoculated, and when the average amount of aphids reached about 50 heads / plan...

Abstract

The invention relates to a method for breeding and feeding Aphidius gifuensis Ashmesd in a floating seedling raising shed and belongs to the field of insect feeding. According to the biological and ecological behaviors of the Aphidius gifuensis Ashmesd and the modern agricultural science and technology, by using the existing floating seedling raising shed and the time difference between Myzus periscae (Sulzer) breeding period and the Aphidius gifuensis Ashmesd larva growth and development period, breeding Aphidius gifuensis Ashmesd required for Aphidius gifuensis Ashmesd breeding is obtained at the same time when the Myzus periscae (Sulzer) is bred. The method for breeding and feeding the Aphidius gifuensis Ashmesd in the floating seedling raising shed has the advantages that the operation is simple to conduct, the cost is low, the repetitive investment is not required, the survival rate is high, the scale breeding is facilitated and the popularization is facilitated. Compared with the method for breeding and feeding the Aphidius gifuensis Ashmesd in a seedling raising greenhouse, on the premise that the bred and fed quantity is not affected, the cost per mu is reduced by RMB4.5, the quantity of bred and fed adult Aphidius gifuensis Ashmesd and the parasitism rate are respectively improved by 21.3 percent and 3.8 percent, the number of parasitic aphids on each plant in the field and the control rate of the Aphidius gifuensis Ashmesd to the aphids are improved by 4.75 percent, the economic benefit, the social benefit and the ecological benefit are good, and a good foundation is laid for the large-scale breeding and feeding of the Aphidius gifuensis Ashmesd.

Description

Technical field: [0001] The invention relates to a method for breeding and raising aphids aphids in small floating nursery sheds, which belongs to the field of insect breeding. Background technique: [0002] The tobacco aphid Myzus periscae (Sulzer) is one of the main pests in tobacco leaf production. Its damage to tobacco plants not only directly affects the growth of tobacco plants and induces soot disease, but also is the main transmitter of viral diseases. It can spread more than 100 kinds of tobacco Virus, which harms more than 170 kinds of crops, has become a worldwide pest and has caused serious losses to tobacco leaf production. Since chemical control has been the mainstay for a long time, the biodiversity in the tobacco field ecosystem has decreased and the environmental ecological balance has been seriously imbalanced. The problem is that pesticide residues in tobacco leaves have seriously affected the quality of tobacco leaves and human health, thus leading to a v...
