Artificial feed for myzus persicae

Abstract

The invention relates to artificial feed for myzus persicae, which comprises 2.5%-3.5% of amino acid mixture, 0.2%-0.3% of ascorbic trace element chelate, 0.1%-0.2% of vitamin B, 17%-20% of cane sugar, 3.0%-4.0% of tobacco juice, 0.4%-0.6% of KH2PO4, 0.1%-0.3% of MgCl2, 6H2O and 72%-75% of redistilled water. The artificial feed with the added tobacco juice has the evident effect on improving survival rate and reproductive rate of myzus persicae feeding the artificial feed. Breeding of myzus persicae with the artificial feed is insusceptible to seasons and available all the year round; mass breeding of myzus persicae is insusceptible to hosts and space; the impact of factors such as microbial infection, pesticides and the like can be relieved or avoided; and standard and uniform experimental myzus persicae is easy to obtain.

Description

technical field [0001] The invention belongs to the technical field of insect feeding, and in particular relates to an artificial feed for aphids. Background technique [0002] For a long time, in the various researches on the important tobacco pest, Aphis persicae, it is very important to ensure the quantity and availability of the tested insect sources for various related researches. At present, the supply of tested insect sources is mainly collected in the field or propagated in the greenhouse by using tobacco seedlings. However, the greenhouse propagation method has the following obvious disadvantages: (1) Due to the obvious seasonality of tobacco growth, the occurrence of aphids in the tobacco growing season is affected by various factors such as climate and environment, so it is difficult to ensure that (2) Using tobacco seedlings to propagate aphids in the greenhouse requires certain greenhouse hardware facilities, and the cultivation and management of tobacco seedli...
