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.
