Description

Technical Field

[0001] This utility model relates to the field of insect egg collection technology, specifically a device for facilitating mating and egg collection of the Asian corn borer. Background Technology

[0002] The Asian corn borer, commonly known as the corn stem borer, is the number one pest affecting corn production in my country. It is widely distributed in a vast area of ​​eastern my country, from Heilongjiang to Guangzhou, causing serious economic losses due to its large affected area. In the field, the Asian corn borer damages sweet corn more severely than common corn. Newly hatched larvae feed on the leaf tissue of the corn whorl and bore through it. During the tasseling stage, the larvae damage the unemerged tassels. After tasseling, the larvae bore into the ear stalk and the stalk above the female ear. During the corn grain-filling and silking stages, the larvae concentrate at the top of the ear and eat the corn kernels.

[0003] Adult Asian corn borers mate on the day of emergence, with females mating multiple times, averaging 4.25 matings. Egg laying begins 1-2 days after mating, primarily on the underside of leaves near the midrib, forming clusters of regular, fish-scale-like eggs. Adult Asian corn borers reproduce most profusely under moderate temperatures (20-28℃) and high humidity (70-100% relative humidity). Reports indicate that females lay the most eggs and have the highest hatching rate at 24℃ and 90-100% humidity. Egg production and hatching rate are positively correlated with ambient humidity, while low humidity is detrimental to egg laying and larval hatching.

[0004] Currently, the commonly used device for mating and oviposition of the Asian corn borer is the mesh cage. The operation procedure is as follows: after the adult moths emerge, multiple pairs of male and female moths are placed in the cage, allowing them to mate freely. After the female moths have laid their eggs, the eggs are collected by manually scraping them from the mesh of the cage.

[0005] The operation steps of this method include pairing adult males and females separately and manually scraping out egg masses. The operation is time-consuming and laborious, and it is easy to damage the egg masses. Most importantly, the open oviposition device makes it impossible to maintain a high level of environmental humidity, which directly affects the lifespan and reproductive capacity of the adults. In addition, it is not convenient to supplement nutrition during the adult stage, which greatly limits the large-scale breeding of Asian corn borers. Utility Model Content
