Problems solved by technology

[0004] At present, the feed used in artificial breeding is flat feed, and the prepared feed is poured into a flat cup or box, which is suitable for pre-2nd instar larvae. After comparison, it is found that the flat feed has a greater impact on the subsequent growth of larvae, which not only prolongs the growth of larvae. During the growth period, the weight of the pupae will decrease, and even the emergence and oviposition of adults will be affected to varying degrees, which will bring hidden dangers to continuous multi-generation breeding

Embodiment 1

[0033] Dilute 15g of agar with 800g of water, stir well, heat to boiling for 10 minutes; add 140g of wheat germ powder, 30g of soybean powder, 15g of yeast powder, 12g of sucrose, 1.6g of sorbic acid, 1.6g of ethylparaben, 4g of ascorbic acid , Vitamin 4g, stir evenly, then heat to boil and maintain a viscous paste for 3 minutes; roll with a screw flaking machine, and then slice with a slicer to make a sheet with a thickness of 0.5mm, a length of 40mm, and a width of 30mm feed.

Embodiment 2

[0035] The larvae of the 2nd instar are transferred to the insect rearing box, which has a built-in curved grid-shaped larva rearing frame, and the rearing frame places the sheet-shaped feed with a thickness of 0.5 mm, a length of 40 mm, and a width of 30 mm prepared in Example 1. The larvae are attached to the rearing frame or the side of the sheet feed, and eat the sheet feed by themselves in the same way as eating leaves in the wild; every 4 days, the larvae are taken out of the insect rearing box and moved into the next one for use. The grid-shaped rearing rack of 100 mm is placed in the insect-raising box with sheet-shaped feed with a thickness of 0.5 mm, a length of 40 mm, and a width of 30 mm. Until the larvae are mature, stop getting food, and then take it out and continue to raise it according to the conventional method.

example

[0043] The first generation of breeding started on May 6, 2010, completed on June 19, and lasted for 45 days; the second generation started on June 19, completed on July 29, and lasted for 41 days. See Table 1 for details:

Abstract

The invention relates to a flaky feed for feeding Geometridae insects, which comprises the following components in parts by weight: 120-160 parts of wheat germ powder, 25-35 parts of soybean meal, 12-18 parts of yeast powder, 10-14 parts of cane sugar, 2.4-4 parts of preservative, 2-6 parts of ascorbic acid and 2-6 parts of vitamin. The flaky feed can greatly improve the feeding level and shortenthe feeding time, and the life cycle duration of the flaky feed tends to be identical with that in the nature, thus achieving the purpose of artificial feeding in a large scale.

Description

technical field [0001] The invention relates to the technical field of insect feed, in particular to a flaked feed for raising chinchilla insects. Background technique [0002] Insects of Geometridae (Geometridae) occupy a relatively important position in agriculture and forestry. We use microbial insecticides in the control of eucalyptus geometrids, mainly tung geometrids (also known as tung geometrids) and gray tea geometrids. In particular, tung inchworm nuclear polyhedrosis virus (NPV) can effectively control tung inchworm and gray tea inchworm, and can effectively control it without causing disasters within a certain period of time, which is in line with the concept of integrated pest management (IPM). [0003] Lepidopteran larvae, like other Lepidoptera larvae, have chewing mouthparts, but the gastropods are quite different. Lepidoptera larvae usually have 5 pairs of gastropods, which are born on the third to sixth and third On the ten abdominal segments, the abdomen ...
