Abstract

The invention discloses a nutrient substance for prolonging the service life of adult bees of aphidius gifuensis ashmead. The nutrient substance is composed of 25% of white sugar, 5% of cane sugar, 5% of glucose, a small number of mineral substances, vitamins, amino acid and copper gluconate and the balance water. The nutrient substance can be supplied to aphidius gifuensis ashmead in the field with aphidius gifuensis ashmead, can provide sufficient nutriment for the growth and development of adult bees of aphidius gifuensis ashmead, prolongs the service life of adult bees of aphidius gifuensis ashmead, improve the activity and oviposition capacity, is low in cost, and guarantees the large-scale propagation and application of aphidius gifuensis ashmead. The aphidius gifuensis ashmead is fed artificially and released in the field, the service life of myzus persicae is shortened and the fecundity of myzus persicae is decreased by more than 90% through oviposiiton and parasitism of female bees on myzus persicae, and the myzus persicae control function is remarkable. The service life of adult bees of aphidius gifuensis ashmead is prolonged, the survival rate of adult bees of aphidius gifuensis ashmead is improved, and large-scale application of aphidius gifuensis ashmead is facilitated.

Description

technical field [0001] The invention belongs to the field of agricultural pest control, in particular to the field of biological control of pests, and in particular relates to a nutrient substance for prolonging the lifespan of an adult bee of Aphids aphidis. Background technique [0002] Myzus persicae (Sulzer), also known as Myzus persicae (Sulzer), is a major pest of tobacco that is distributed worldwide and commonly occurs in various tobacco producing areas in my country. It not only absorbs the nutrition of tobacco plants, excretes honeydew, and directly affects The yield and quality of tobacco leaves are not only affected, but also a variety of tobacco viruses are transmitted, causing the occurrence and prevalence of various viral diseases and other insect-borne tobacco diseases. However, the long-term and large-scale application of chemical agents leads to the increase of drug resistance of aphids, and the natural enemies are difficult to survive under the conventional...
