Description

Breeding device and method for experimental population of cassava single-claw mites
Technical Field
The invention relates to the technical field of cultivation and the field of agricultural mites, in particular to a large-scale artificial feeding technology for cassava single-claw mites; more particularly, the invention relates to a breeding device and a breeding method for a cassava single-claw mite experimental population.
Background
Cassava (Manihot esculenta Crantz) is one of three tuber crops in the world, is a staple food and an important industrial raw material for the survival of nearly 8 hundred million people in the world, belongs to euphorbiaceae (Euphorbian jceae) and cassava (Manihot) sub-shrub perennial crops, is native to amazon river basin in tropical areas of america, and is widely planted in tropical and subtropical areas. Introduction and cultivation of China in the 20 th century of 19 th century are widely distributed in the south China area, and small amounts of cultivation are also available in the southwest and China areas. Two species (Mononychellus mcgregori and Mononychellus tanajoa) of cassava single-claw mites, namely cassava green mites, are found in China at present, belong to the genus Tetranychidae (Tetranychidae) of the arachnidae (Arachnida) and are one of important destructive mites in tropical areas, are important quarantine pests in the world, mainly suck leaf tissue cells at the backs of cassava leaves by a needle, cause leaf chlorosis and yellow, and lead to dry branches and death of the whole plant in serious cases. In 1970, cassava single-claw mites are transferred into the Ucada from south America, and later, african countries such as Kennia, tank Sannnia, congo and Sudan burst into disasters successively, and are widely distributed in the planting countries of the Africa, the south America and the Asia between 30 degrees of north and south America at present, so that the cassava single-claw mites are one of important mites for the cassava. The cassava single-claw mites are found in the southwest state for the first time in 2008, are distributed in the southwest, yunnan, guangxi and Guangdong cassava planting areas at present, and have a trend of aggravating hazard every year. Because the cassava single-claw mites have small individuals, short propagation period, overlapped generation and large occurrence quantity, are hidden on the leaf backs and are harmful, the medicament control difficulty is high. How to effectively solve the technical problem of indoor artificial mass raising of the cassava single-claw mites, meet the actual demands of the system for developing researches on biology, ecology, host selectivity and the like, and research and development of green prevention and control key technologies and the like, effectively solve the contradiction between safe and effective prevention and control of the cassava single-claw mites and safe large-scale planting of the cassava, and become an important subject to be solved urgently in the cassava industry in China.
In the literature records, no report on the indoor mass feeding of cassava single-claw mites is yet seen, and only other methods for artificially feeding mites comprise an in-vitro leaf feeding method, a living plant feeding method and a bottle feeder feeding method: (1) In-vitro leaf feeding method, in-vitro leaves are horizontally spread on wet water-absorbing materials for moisturizing and fresh-keeping, water-absorbing paper strips or isolating strips are placed around the leaves to prevent mites from escaping, but the method is difficult to ensure stable humidity conditions suitable for development and propagation of harmful mites, and water in a feeder is easy to lose, so that a great risk of sudden and rapid death of the harmful mites exists; (2) In the living plant raising method, a plastic bag is sleeved on branches of host plants where mites are located, and the other ends of the branches are pricked by rubber bands to form a cage which is covered in a plastic cover for raising, but the stability of raising conditions is difficult to ensure, and particularly, because the leaves of the host plants are large, the required plastic bag is also large, and the mites are tiny in size and extremely easy to escape or die; (3) The bottle-shaped feeder feeding method is characterized in that leaves and moisturizing materials are placed in small bottles in a layered mode to feed, the surfaces of the leaves are dry and clean, the leaves are easy to keep fresh, but the provided feeding space is too small, the operation is not easy, and after adult mites are fed into the feeding space, not only are mites extremely easy to escape, but also eggs are difficult to collect, and the mite feeding amount in each bottle is small. Therefore, the number of experimental populations is difficult to ensure by the three methods, the actual requirements cannot be met, and the method is not suitable for indoor feeding of cassava single-claw mites.
