Description

Device for obtaining walnut lifting moth eggs in batches

Technical Field

The utility model relates to a device for obtaining eggs of walnuts lifted by limb moths in batches.

Background

Walnut limb lifting mothAtrijuglans hetaohei Yang belongs to lepidoptera and acromoth families, is a main pest on walnuts, occurs in all walnut producing areas in China, and eats walnut fruits and kernels with larvae. The damaged fruit skin is blackened and shriveled, and the kernels are dried and darkened, so that early fruit drop is caused, the yield and the commodity value of the walnuts are seriously influenced, and the damaged fruit skin is also named as 'walnut black' and 'black walnuts'. In recent years, with the expansion of walnut cultivation area and the introduction of new varieties, the walnut limb moth is commonly generated in each production area, the damage is gradually increased, the fruit damage rate is usually up to 70% -80%, even up to 100%, and the serious yield reduction is caused. Because the insect is damaged when entering the fruit, the difficulty of preventing and controlling the pesticide is increased, and the comprehensive measuring and reporting technology is required to be applied in the production. Besides, the drug resistance of the walnut limb moth to the medicament, the indoor toxicity test of the medicament and the research in the aspect of molecular biology need to be researched indoors. Therefore, batch of insect states are required to be used as test objects in both walnut limb moth field and indoor research. At present, most of the original sources of the walnut limb lifting moths for the test are field catching, field egg collecting and field summer cocoon overwintering cocoons digging, but the methods mainly have the following problems: (1) enabling the walnut limb moth to generate 1-2 generations in one year, enabling female worms to lay eggs on fruit surfaces in the emergence period of the walnut limb moth adults, and crawling for several minutes after hatching to eat fruits; because the time from the larva hatching to the fruit-eating is short, great difficulty is brought to catching, and even a small amount of larvae are caught, the larvae are difficult to be used for developing research experiments due to inconsistent instar periods;

(2) the walnut limb moth overwinter with the mature larvae in soil, the overwinter depth can be on the soil surface, and the deepest depth can reach more than 10cm, but the obtained amount of manually dug larvae is small, so that the later-period test requirements cannot be met. The method of collecting the larvae by using a conventional plastic box or smashing the walnuts by using an artificial axe is adopted by the applicant for two years, so that the death rate of the obtained larvae is high, the emergence rate of adults is low, the egg laying amount of the adults is low, and the ideal amount of the adults is not obtained; secondly, because of the inconsistency of the fruit-eating period, the eclosion, the oviposition and the growth and the development of the collected mature larva are irregular, the physiological state is inconsistent, a better test sample cannot be formed, the research result is greatly influenced, and the significance of the research result is lost.

Therefore, the difficulty of obtaining larvae in batches from the field or collecting the larvae by a conventional method and effectively laying eggs is high, and the obtained larvae have the problem of large individual difference and are not beneficial to later-stage research, so that a method for effectively and comprehensively preventing and treating the walnut limb lifting moths is urgently needed, wherein the method can obtain all insect states in batches, is uniform in development and has consistent physiological state.

Disclosure of Invention

For solving above technical insufficiency, the utility model provides a device of limb moth's ovum is lifted to the walnut of obtaining in batches can reduce time in a large number, has improved adult eclosion rate and egg laying volume.

The utility model discloses a realize through following measure:

The utility model has the advantages that: the device of the utility model is simple in structure, when a large amount of reduction time, improved adult eclosion rate and egg laying volume, collect and pound the walnut with the manual work and collect larva save time 29.6~59.4 times than conventional plastic box, adult eclosion rate improves 1.31~1.99 times, and egg laying volume improves 1.55~5.72 times. 2. The utility model discloses device and method can replace conventional plastic box and collect the larva, artifical pound the walnut and collect larva and spawning device under the conventional mode, have solved the plastic box and have collected the larva, artifical pound the walnut and collect larva injury mature larva, are unfavorable for the problem of adult eclosion and productivity. Can greatly reduce time, improve the eclosion rate and the egg laying amount of the imagoes and has better application prospect.
