Artificial feed for peach borer larvae, its preparation method and feeding method for peach borer

Abstract

The invention discloses an artificial feed for peach borer larvae, a preparation method thereof and a feeding method for peach borer. The artificial feed for peach moth larvae comprises, in parts by mass, 40-60 parts of raw wheat germ, 20-40 parts of soybean powder, 65-85 parts of chestnut powder, 10-30 parts of milk powder, and 10-20 parts of yeast powder, 20-30 parts of sucrose, 2-7 parts of multivitamins, 15-25 parts of agar, 1-2 parts of corn germ oil, 0.5-2 parts of ethyl paraben, 1-3 parts of ascorbic acid, 1 part of 30-40% formaldehyde solution ~3 parts, 800~1200 parts of water. Adopting the peach moth larva artificial feed of the present invention to carry out the raising of peach moth, not only can obtain higher larval survival rate, pupation rate, eclosion rate, male and female adult life span, single female egg laying capacity etc., improve the hatching rate of ovum, Moreover, the preparation process is simple and convenient, and the operability is stronger.

Description

technical field [0001] The invention relates to the technical field of peach borer feeding technology, in particular to an artificial feed for peach borer larvae, a preparation method thereof and a feeding method for peach borer. Background technique [0002] Conogethes punctiferalis belongs to Lepidoptera and Crambidae, also known as peach moth, leopard moth, peach borer, peach borer moth, etc., and its larvae are commonly known as heart moths. There are more than 100 species of host plants, which will harm various fruit trees, forest trees and crops such as apples, pears, apricots, chestnuts, corn, sorghum, and sunflowers. In recent years, with the change of farming system and climate, the harm of peach borer has become more and more serious, especially in the Huanghuaihai summer corn area, peach borer has become another major pest of corn after the Asian corn borer, even in some The population of the area has surpassed the corn borer. Peach borer damages corn mainly on ...

Problems solved by technology

At present, there are mainly two indoor artificial breeding methods for the peach borer, one is to use the fruits of the natural host plants of the peach borer such as chestnut and corn to raise it. This method is a traditional breeding method, which is simple and easy to operate. However, there are some problems as follows: (1) the fruit of the natural host plant of the peach borer is limited by the growing season, and fresh fruit feed cannot be provided at any time, which causes difficulties for annual feeding; (2) the fruit feeding of the natural host plant Insects, especially when chestnuts are used to raise them, the cost is relatively high; (3) It is difficult to disinfect fresh fruits, such as corn ears, which are easy to mold and difficult to disinfect, resulting in poor feeding effect; (4) The larval state is difficult to control and neat. sex, poor consistency

Another kind is to carry out the raising of peach borer by artificial feed, and wherein, report earlier is the simple feeding method of the disclosed peach borer such as Honda, and its feed formula is by containing corn, wheat, rice bran, vitamin and trace substance Feed powder, soybean powder, dry sawdust, agar powder, and water. This method is a useful attempt to raise artificial diets for the peach borer moth, but the survival rate of larvae raised by this formula is low.

[0004] Chinese patent document CN 103478493 B discloses a kind of artificial feed for peach borer, which consists of chestnut powder, corn flour, peach powder, soybean powder, brewer's yeast powder, multidimensional glucose, complexin, cholesterol, ascorbic acid, erythromycin, agar powder , methyl paraben, methyl p-hydroxybenzoate, etc.; studies have shown that the feed formula in this technical scheme can improve the survival rate of the peach moth and reduce the feeding cost, but the egg production per female, the life span of male and female moths and Egg hatching rate and other indicators are low

[0005] Chinese patent document CN 104304694 B discloses a kind of artificial feed for peach borer, which mainly consists of wheat germ, soybean powder, dry powder of corn seedlings, dry powder of chestnut, yeast extract, potassium sorbate, ethyl p-hydroxybenzoate, vitamins, corn Composed of germ oil, trehalose, etc.; the preparation method of corn seedling dry powder is as follows: (1) take an appropriate amount of corn, wash it, and cultivate it to the three-leaf stage; (2) kill the corn seedlings, and then dry them to constant weight; (3) ) pulverize the dried corn seedlings and sieve them to obtain dry corn seedling powder; although the formula in this technical scheme solves the problems of low egg production and poor subculture to a certain extent, it realizes the indoor continuous production of peach moth moth. The need for multi-generation feeding; however, the larval survival rate and egg hatching rate of this formula need to be improved; in addition, this formula is relatively cumbersome, especially the preparation process of corn seedling dry powder, which needs to be cultivated, raised, killed, dried, and crushed indoors Wait
