Artificial feed for lygus lucorum

Abstract

The invention relates to a feed for artificially breeding lygus lucorum. The feed comprises fresh egg, yolk powder, lecithin, sucrose, yeast powder, sorbic acid and the like which serve as main components. The artificial feed is suitable for artificially breeding a large quantity of adults and nymphs of the lygus lucorum, the bred lygus lucorum has high survival rate and quick growth and development, the average egg laying amount of single female lygus lucorum is high, the feed has long quality guarantee period, the frequency of changing the feed is greatly reduced, time and labor are saved, and the cost of the feed is reduced. The feed has the characteristics of simplicity and strong practicability, and is easy to operate.

Description

technical field [0001] The invention relates to the field of insect breeding, in particular to an artificial feed for raising Lygus spp., more specifically, to an artificial feed for feeding adults and nymphs of Lygus spp. Background technique [0002] The green Lygus is an important pest that harms cotton in my country, and it is distributed in both the Yangtze River Basin and the Yellow River Basin. The damage to cotton by Lygus spp. lasts for a long time, from seedlings to boll opening stage, and the damage period lasts for more than 4 months. The green Lygus uses piercing-sucking mouthparts to pierce cotton tender heads, growth points, young buds, and young bells to suck the juice. The tips of the growing buds at the cotyledon stage are damaged, blackened, withered, and no longer grow; after the emergence of true leaves, the terminal buds are damaged and die, and the branches and buds grow in clusters, becoming "multi-headed cotton"; when the young leaves are damaged, t...

[0006] Our country is relatively lagging behind in the development of artificial feed for mirid bugs. Host plants such as cotton and potatoes have been used to raise mirid bugs, mirid bugs, three-spotted mirid bugs, and alfalfa mirid bugs. Using green beans (and as a substrate for oviposition) to raise Lygus aeruginosa and Lygus alfalfa has achieved good results. They can be reared indoors for multiple generations. The supply of beans is also difficult to guarantee, which brings difficulties to the artificial breeding of green ligudoma. At the same time, the feeding of green beans requires frequent renewal of feed, which is labor-intensive and time-consuming, and the cost is high

Song Guojing et al. (Using orthogonal test method to optimize the formula of artificial diet for Lygus nymphs, Plant Protection, No. 6, 2010) developed the formula of artificial diet for Lygus nymphs on the basis of foreign formulas. The developmental period of Lygus nymphs raised by this formula is extended by 1 day, and the survival rate is not significantly improved, and there are as many as 10 important ingredients in this formula, and the cost is high; Feeding, only has a certain effect on 3rd and 4th instar nymphs, and is not suitable for feeding adults of green Lygus bugs
