Description

Wild rice stem rust fungus gall midge's field release

Technical Field

The utility model belongs to the technical field of the insect is bred, concretely relates to field release of wild rice stem rust fungus cecidomyiia.

Background

The wild rice shoots, namely the wild rice shoots, the wild rice melons and the wild rice heads belong to gramineae perennial shallow water herbaceous plants and are one of the special and important aquatic vegetables in China. Because of the rich nutritive value and higher economic benefit, the water bamboo is popular with consumers and farmers. The vegetables are planted in Zhejiang river and Taihu lake watershed mostly. In recent years, due to the influences of factors such as large-area planting of the water bamboo (particularly continuous expansion of the cultivation area of the water bamboo in a greenhouse), climate change and the like, the problem of water bamboo diseases is prominent, particularly, the rust of the water bamboo is the most common and increasingly serious, so that great economic loss is caused. At present, chemical bactericides are mainly applied to preventing and treating the rust disease of the water bamboo, but the long-term abuse of the chemical bactericides can obviously reduce the preventing and treating effect of the rust disease of the water bamboo, the water bamboo stem-forming rate is obviously reduced, even the water bamboo does not form the water bamboo, and the healthy and stable development of the water bamboo industry is seriously influenced.

Zizania latifolia rust gall midge: (Mycodiplosissp.) genus of Diptera order, gall midicidae family, completely abnormal insects. The larva takes and eats the rust fungus prunella of the leaf of the wild rice stem. The mature larva mainly forms white thin cocoon-shaped pupa on the back of the leaf. Eclosion of adults lay eggs near the summer sporophyte. Because the wild rice stem rust gall midge is a natural enemy of the rust of the wild rice stem, the rust is controlled by artificially propagating the rust gall midge and releasing the rust midge to the field, the method is one of important measures for changing the current treatment mode mainly based on chemical pesticide control, and has very important practical significance. Therefore, through biological control of 'treating diseases with insects', artificially releasing the wild rice stem rust gall midge in the field to control the rust disease of the wild rice stem becomes one of important measures of a green control technology of major diseases and insects of the wild rice stem.

Although the wild rice stem rust fungus gall midge has high potential utilization value in the aspect of biological control of the wild rice stem rust disease, the feeding, batch propagation and release of the wild rice stem rust fungus gall midge are the basis of natural biological control. However, the use of rust gall midges in biological control is not open to morphological, biological, physiological and biochemical studies, but the development of these studies is smooth and requires a consistent progression of larval development (including pest status, age, size, health, sensitivity, etc.). Meanwhile, ecological tests (pupation rate, eclosion rate and the like), biochemical tests and field demonstration applications all need a large amount of gall mosquito pupae. To meet such requirements and ensure the accuracy of research results, large-scale artificial feeding is necessary.

In order to fully develop the biocontrol efficiency of the wild rice stem rust fungus gall midges and ensure the effectiveness, timeliness and pertinence of biological control, an efficient and simple wild rice stem rust fungus gall midge release technology must be perfected so that the wild rice stem rust fungus gall midges emerge at a proper time and the aim of effectively controlling the rust disease of the wild rice stem is fulfilled. Under natural conditions, a large number of natural enemies of the wild rice stem rust fungus gall midge, such as spiders, parasitic bees, stinkbugs, pathogenic fungi and the like, seriously affect the rust fungus gall midge number; meanwhile, the dryness degree of the leaves of the wild rice shoots directly influences the moisturizing effect of pupae. The emergence rate of the wild rice stem rust gall midge imagoes is low due to the factors, and the control effect of the gall midge on the wild rice stem rust disease is seriously influenced. Under natural conditions, external factors (such as complex weather conditions including typhoon, rainstorm, sunshine insolation and the like) are the bottleneck of death in the pupation and emergence processes of the rust fungus gall midges of the wild rice stems, a large amount of the rust fungus gall midges of the wild rice stems die before emerging, and the biocontrol effect is obviously reduced. Therefore, a novel field device for artificially releasing the wild rice stem rust gall midge is urgently needed to be developed, and the dilemma that the wild rice stem rust gall midge dies a lot in pupation and emergence processes is reduced.
