Embodiment 1

[0027] Embodiment 1 (host plant: wild almond tree)

[0028] (1) Breeding room construction: the breeding room is equipped with a bee breeding shed, which adopts a steel frame galvanized pipe connector structure, which is easy to install and disassemble. The bee breeding shed is equipped with an outer cover insect-proof net, thermal insulation plastic film and shade The net has three layers of nets, which have the functions of heat preservation, shade and rain protection. The whole bee breeding shed is 25m long x 20m wide x 3.54m high, with a building area of ​​480m 2 The two conjoined solar greenhouses; the column spacing is 3m, the span is 6m, and the arch distance is 0.75m. The entire greenhouse is equipped with 4 sets of film rolls installed on both sides of the greenhouse and the roof, and there are 2 sliding doors, 1 for the front and the rear. The semi-automatic sunshade net device is used to control the sunshade net in the shed. In order to strengthen the stability of ...

Embodiment 2

[0049] Embodiment 2 (host plant: peach tree seedling)

[0050] (1) Breeding room construction: the breeding room is a steel frame glass structure, 25m long, 20m wide, 4m high, with a building area of ​​500m 2 , The entire solar greenhouse is equipped with shading nets, 1m wide walkways, and 80-90 mesh insect-proof nets are used as the isolation layer of the bee shed.

[0051] (2) Host plant cultivation and management: In the breeding room, select 2-3 year old peach tree cuttings to grow and reproduce in nutrient soil. The nutrient soil is composed of seedling substrate and tobacco field soil by weight 1: 1. The row spacing of cuttings is 10. ~15 cm. After the cutting saplings survive, in the second spring, use a nitrogenous aqueous solution with a concentration of 750-1000ppm for watering to promote the germination and growth of the leaves; the cultivation temperature is 10-20°C, the humidity is 40-60%, in an environment with sufficient light and suitable temperature and humi...

Abstract

The invention discloses a method for quickly breeding aphidius gifuensis. The method includes steps of host plant cultivation, insect species breeding, bee species breeding and aphidius gifuensis breeding, a wild ansu apricot tree or peach tree seedling is selected as a host plant, and a puerile treetop produced from the seedling after water-fertilizer culture is subjected bee breeding for about 35-45 days, which is a reduction of 30 days when compared with using tobacco for seedling breeding. The host plant can be grafted with aphid after leaf buds germinate and leaves unfold on March of early spring, so that time for first-time breeding of aphidius gifuensis in tobacco-growing areas of Northeast China is shortened, and the problems of frost influence, high breeding energy consumption, low activity of aphidius gifuensis, staggering of bee breeding peak and aphid appearing peak and irregular mummified aphidius gifuensis forming are solved. By the method, bee breeding cost is lowered, and using range of aphidius gifuensis is widened; the host plant of five years old can breed more than 50 thousand myzus persicae, braconid parasitism rate is up to 80%, mummified aphid forming rate of the host plant is up to higher than 75%, and each host plant can breed mummified aphidius gifuensis and can prevent and control different crops by more than 60 mu.

Description

technical field [0001] The invention relates to the technical field of biological control of agricultural and forestry pests, in particular to a method for rapidly propagating Aphids aphids by using wild apricot or peach saplings of arboraceae plants in the process of biological control of agricultural and forestry pests. Background technique [0002] Aphids spread viral diseases and form coal pollution, which seriously affects the production and quality of agricultural products. People mainly control them by spraying chemical pesticides, which makes the drug resistance and drug resistance of aphids continue to increase, and the use of chemical pesticides increases year by year. , causing pollution to the environment, threatening the quality and safety of agricultural and forestry products, and affecting people's health. Through the large-scale propagation of aphids by wild almond trees, the occurrence of aphids has been effectively controlled, and the goal of green, healthy...
