Embodiment 1

[0014] A method of using bean aphid and artificial feed to cooperate with raising lady beetles. 30 insects; put a layer of napkin at the bottom of the rearing box before putting in the ladybugs, and place a piece of egg collection paper in the corner of the rearing box to collect the ladybug eggs; put 1600 aphids every day, with a breathable lid on the box, every day Observe the egg-laying situation of ladybugs and replace the egg-laying paper; cut the eggs from the egg-laying paper and put them in the rearing box; before the eggs hatch, transfer the eggs to the larvae rearing box, the arrangement method of the larvae rearing box The same adult feeding box, each box raises 30 larvae; 500 aphids are placed in the feeding box of the 1st-year-old lady beetle larvae every day; After the pupa, take out the pupa, put it into the rearing box, and then carry out a new round of rearing until the ladybug emerges.

Embodiment 2

[0016] A method for using bean aphid and artificial feed to cooperate with raising the small thirteen three-star ladybugs. Put a layer of napkins at the bottom, and then place a circular plastic plate with a diameter of 5cm in one corner of the rearing box to hold artificial feed, and place an egg collection paper in the other corner to collect ladybug eggs; put 2,700 aphids and 5g of artificial feed every day, the box Put on a ventilated lid; observe the egg laying of ladybugs every day, and replace the egg-laying paper; cut the eggs from the egg-laying paper and put them in the rearing box; before the eggs hatch, transfer the eggs to the larval rearing box , the arrangement method of the larvae rearing box is the same as the adult rearing box, and each box raises 50 larvae; 900 aphids are put into the rearing box of the 1-year-old lady beetle larvae every day; Aphids are put into the rearing box of the 2-3-year-old lady beetle larvae every day. 1500 and 3g of artificial feed...

Embodiment 3

[0018] A method for using bean aphid and artificial feed to cooperate with raising the small thirteen three-star ladybugs. The collected provenance of ladybirds is put into a rearing box, and 30 ladybirds are put into each box; Put a layer of napkins at the bottom, and then place a circular plastic plate with a diameter of 5cm in one corner of the rearing box to hold artificial feed, and place a piece of egg collection paper in the other corner of the rearing box to collect ladybug eggs, and put 3g of artificial feed every day. Breathable box lid; observe the egg laying situation of ladybugs every day, and replace the egg laying paper; cut the eggs from the egg laying paper and put them in the rearing box. Before the eggs hatch, the eggs are transferred to a larvae rearing box. The arrangement method of the larvae rearing box is the same as that of the adult rearing box, and each box raises 30 larvae; 900 aphids are placed in the rearing box of the 1st-year-old lady beetle larv...

Abstract

The invention relates to a method for feeding Lenodylaea parviflora by using the combination of bean aphids and artificial feed, which comprises the following steps: collecting Lenodylaea parviflora seed sources from the field, putting the collected Lenodylaea parviflora seed sources into feeding boxes, and putting 30-50 Lenodylaea parviflora into each box; before the ladybirds are put into the breeding box, a layer of napkin is arranged at the bottom of the breeding box, a round plastic plate with the diameter of 5 cm is placed at one corner of the breeding box for containing artificial feed, egg collecting paper is placed at the other corner of the breeding box for collecting ladybirds, aphids and the artificial feed are put into the breeding box, and a breathable box cover is arranged on the breeding box; the egg laying condition of the ladybirds is observed every day, the egg laying paper is replaced, and eggs are cut off from the egg laying paper and put into a feeding box; before eggs are hatched, the eggs are transferred into larva feeding boxes, the arrangement method of the larva feeding boxes is the same as that of adult feeding boxes, 30-50 larvae are fed in each box, and aphids and artificial feed are put in the larva feeding boxes; after the larvae are mature, the pupae are taken out and put into the feeding box, and a new round of feeding is carried out after the ladybirds are subjected to eclosion.

Description

technical field [0001] The invention belongs to the biological control technology, relates to a breeding method of natural enemy insects, and in particular relates to a method for raising small three-star ladybugs by using bean aphid and artificial feed in combination. Background technique [0002] The little three-star lady beetle is an important predatory natural enemy of small insects such as aphids and spider mites. It mainly preys on tea aphid, cotton aphid, locust aphid, wheat aphid, bean aphid, millet aphid, and lotus aphid. , alfalfa spotted aphid, spider mites and other pests. The body length is 6.0 to 9.5 mm, and it is a medium-to-large small thirteen-star ladybird species. The results of the study on the functional responses of the adults of the small three-star ladybug to the radish aphid showed that the daily maximum predation amounts of the little three-star ladybug on the radish aphid and the bean aphid were about 78 and 88 heads, respectively, indicating tha...
