Abstract

The invention discloses a kind of indoor bioassay method of non-selective identification Soybean Resistance eating-core bean worm, belong to soybean insect resistance capacity indoor appraising method technical field.Described assay method comprises the following steps:Pairing eating-core bean worm adult is accessed into beanpod, constant-temperature moisture-keeping in constant-temperature shaking incubator is put into and is incubated the eating-core bean worm ovum grain obtained with blackhead;The beanpod pod wall of the eating-core bean worm ovum grain with blackhead of culture is cut into pieces, each small pieces have 2 ovum grains with blackhead, it is inoculated with the non-selective experiment of newly hatched larvae, the eating-core bean worm work borer population that culture of pests is survived on the 6th~8 day in investigation beanpod one by one using each beanpod.The method of the present invention reduces the error of Soybean Resistance heart-eating worm indoor biometricses qualification result, it is inoculated with the non-selective experiment of newly hatched larvae one by one using each beanpod, ensure there is newly hatched larvae on each beanpod, the contact probability of beanpod and newly hatched larvae is allowed to be consistent, so as to improve the accuracy of qualification result.

Description

A kind of indoor bioassay method of non-selective identification Soybean Resistance eating-core bean worm
Technical field
The present invention relates to a kind of soybean insect resistance capacity indoor appraising method, more particularly to a kind of non-selective identification Soybean Resistance The indoor bioassay method of eating-core bean worm.
Background technology
Current Soybean Resistance heart-eating worm indoor bioassay is main to be equal to design in 2011 by Northeast Agricultural University's Han Lan hazes Disk split plot design (the such as Li Tingting, Han Lanlan, Zhao Kuijun " application of the disk split plot design on genetically engineered soybean insect resistance identification "《Make Thing magazine》2011,4:20-22).This method is under the suitable temperature and humidity conditions of insect growth, by being placed on circular filter paper The newly hatched larvae at center equidistantly randomly places the trend and moth food, death condition of beanpod to disk periphery to judge that insect resistace is poor It is different.Disk split plot design identifies that soybean is a kind of selectivity experiment to eating-core bean worm resistance capacity, but eating-core bean worm is to posting Main selection is that occur to carry out the beanpod of host selection spawning in Adult worms producting eggs stage, i.e. adult, newly hatched larvae directly eat into Place beanpod, rather than larva are selected beanpod.This method allows newly hatched larvae independently to randomly choose beanpod, it is impossible to meet every There is newly hatched larvae on individual beanpod.So the probability that beanpod is contacted with newly hatched larvae is inconsistent, the qualification result thus increased Error.
The content of the invention
It is an object of the invention to overcome shortcoming present in above-mentioned prior art with deficiency, there is provided the non-selective mirror of one kind Determine the indoor bioassay method of Soybean Resistance eating-core bean worm.This method is tied to reduce the identification of Soybean Resistance heart-eating worm indoor biometricses The error of fruit, the non-selective experiment of newly hatched larvae is inoculated with using each beanpod one by one, it is ensured that is had on each beanpod and is just incubated children Worm, allows the contact probability of beanpod and newly hatched larvae to be consistent, so as to improve the accuracy of qualification result.
The purpose of the present invention is achieved through the following technical solutions:A kind of room of non-selective identification Soybean Resistance eating-core bean worm Interior bioassay method, comprises the following steps:
(1) prepare for examination insect:The adult production for being connected to beanpod is put into after the eating-core bean worm adult pairing that field is gathered In ovum cage, each spawning cage is put into 40~50 pairs of pairing eating-core bean worm adults, and fresh beanpod is changed daily and supplies Adult worms producting eggs, will Beanpod with ovum is put into constant-temperature moisture-keeping in constant incubator and is incubated, and treats that egg hatching checks the development progress of ovum daily, when ovum grain Occur after blackhead, obtain the eating-core bean worm ovum grain beanpod with blackhead;
(2) preparation of soybean material:The consistent beanpod of growth is gathered in field, valve bag is put into and takes back, each culture dish 10 beanpods are put into, beanpod is closely spaced together, the base portion of beanpod is encased with moisturizing cotton balls, and moisturizing is stand-by, and preparation is obtained The culture dish of soybean pod must be carried;
(3) the beanpod pod wall for the eating-core bean worm ovum grain with blackhead for obtaining step (1) is carefully cut, and knife is used after counting Piece cuts the beanpod pod wall of the eating-core bean worm ovum grain with blackhead into pieces, and each small pieces have 2 ovum grains with blackhead, use tweezers Small pieces are transferred in step (2) in the culture dish with soybean pod, there are 2 bands to each beanpod access is a piece of in culture dish The pod wall of the ovum grain of blackhead, is put into insectary and cultivates by 20 altogether, and pod is voluntarily eaten into after it is hatched;
(4) culture of pests pushes the eating-core bean worm work borer population survived in beanpod investigation beanpod aside after 6~8 days, realizes non- The indoor bioassay of selectivity identification soybean insect resistace.
The temperature that constant-temperature moisture-keeping described in step (1) is incubated is 25 DEG C, and relative humidity is 80%.
Counting described in step (3) is preferably to be counted under stereoscope.
The condition cultivated in culturing room described in step (3) is that temperature is 25 DEG C, and relative humidity is 80%.
The present invention has the following advantages and effect relative to prior art:
The method of the present invention reduces the error of Soybean Resistance heart-eating worm indoor biometricses qualification result, is connect one by one using each beanpod Plant the non-selective experiment of newly hatched larvae, it is ensured that have newly hatched larvae on each beanpod, make contact of the beanpod with newly hatched larvae several Rate is consistent, so as to improve the accuracy of qualification result.
