Description

A kind of man-made feeds of loxostege sticticalis, its preparation method and method for breeding
Technical field
The present invention relates to insect feedstuff and breeding technology, and in particular to the man-made feeds of loxostege sticticalis, its preparation method and adopts With the method for breeding of the feed.
Background technology
Loxostege sticticalis Loxostege sticticalis L belong to Lepidoptera Lepidoptera, and Crambidae Crambidae is one Kind of host range extensively has fulminating farming and animal husbandry insect very much, from 1949 so far in northern China farming and pastoral area 3 cycles Property break out, to locality farming and animal husbandry cause huge economic loss (Luo Lizhi, Huang Shaozhe, Jiang Xingfu, Zhang Lei .2009. China The big generation feature of loxostege sticticalis in 2008 and genetic analysis plant protection, 35:27-33.).Its larva has cybotaxis, migration And the features such as binge, highdensity loxostege sticticalis larva usually all eats only surplus plant all in plot during big generation Polished rod.And its adult has the habit migrated at a distance, low instar larvae has concealed feature, thus the generation of loxostege sticticalis again Relatively it is difficult to initial stage find, it is hard to guard against.The resistance to the action of a drug of loxostege sticticalis larva is relatively low, and in general medicament can just be carried out well to it Control, in terms of the domestic preventing and treating center of gravity for loxostege sticticalis is concentrated mainly on prediction, enter the instar larvae of gluttony phase 3 in loxostege sticticalis Controlled it in the past just can bottom line reduction loss.In agricultural production practical application, loxostege sticticalis can be used as important Agricultural pests parasite is such as:The prolific host such as parasitic wasp, tachinid.And the low characteristic of its resistance to the action of a drug can be used for Carry out screening, measure and the resistance mechanism research of agricultural chemicals.And these are required for large batch of, the consistent loxostege sticticalis larva of development.Mesh Before, loxostege sticticalis is mainly using the raising of the natural feed such as goosefoot leaf, clover, due to that must change by seasonality and repeatedly feed Limitation, using natural feed it is difficult to expand the raising scale of loxostege sticticalis;And natural feed is not easy to uniformly add and surveyed for raw Medicament;Therefore, loxostege sticticalis man-made feeds and crucial breeding technology are developed, realizes that the extensive, long-term of test worm, continuously rearing are Carry out the important content of its integrated control technique research and production application.
The domestic development to loxostege sticticalis larva artificial feed has been carried out largely studying.Wang Yannian in 1984 etc. is published 《Insect artificial diet's handbook》A kind of full man-made feeds of loxostege sticticalis are recorded in book and one kind are meridic diets, two kinds of feeds Number has all continuously been raised for loxostege sticticalis larva (Wang Yannian insect artificial diet handbook .1984. Shanghai:Shanghai science and technology is published Society .P297).Wang Yi in 1987 etc. is primary raw material manufacturing artificial word material with grey dish seedling stage leaf powder, feeding effect preferably (Wang Yi, Zhang Lvhong, Zhang Likun .1987. loxostege sticticalis and 5 kinds of quaker moth Easy manual feed Dongbei Agricultural College journal .18 (02): 179-181).Pan Hong jade in 1991 is raised with artificial diets for cabbage armyworm, Mamestra brassicae to loxostege sticticalis, and has raised two more than generation (Pan Hong Yu, the development Jilin Auto Industries of a great .1991. artificial diets for cabbage armyworm, Mamestra brassicae,:17-19+93-94.).2012 Wu Jinhua etc. have developed loxostege sticticalis man-made feeds (the Wu Jin China .2012. loxostege sticticalis larva people of the addition leaf factor by experience screening The research of work feed and its effect assessment Agricultural University of the Inner Mongol, 43).Above-mentioned work solves to a certain extent really grinds Study carefully to the problem of loxostege sticticalis standard worm sources demand in work, but still the high-volume of test worm, the raising in anniversary, subculture can not be realized. Existing subject matter has:(1) its method for breeding is complex, larval phase is long, and eclosion rate is relatively low, moth weight is lighter, it is difficult to quilt It is widely used.(2) antiseptic effect is poor, need to repeatedly change feed, time-consuming, laborious.
