Characteristics and life traits of pea weevils

The characteristics of pea elephants and life characteristics are as follows:

Peas are a kind of twining herbaceous plants, there is no hair on it, the leaf blade is usually long ovate, the length of about 3 centimeters or so, and its pods are in the form of an oblong posture, the length of about 6, 7 centimeters or so, peeling off the skin of the pods, which reveals the greenish peas, and will turn yellow when it is ripe. After maturity, it will become yellow, the main places of origin are Henan, Hubei, Jiangxi, Sichuan, Qinghai, Guizhou, Anhui and other places.

Peas are a kind of twining herbaceous plants, there is no hair on the top, the leaf blade is usually long ovate, the length of about 3 centimeters or so, its pods are oblong posture, the length of about 6, 7 centimeters or so, peel off the skin of the pods, which reveals the green peas, after maturity will become yellow.

The pea weevil has a longer antennae on its head, which is filamentous, but the female antennae are thicker than the male antennae, which is an important feature to distinguish between male and female weevils. The antennae of males are longer than those of females, and the adult body is 4-6 mm long and slightly oval. In the life history of the pea weevil, mature eggs are produced and stored in the reproductive tract of the female, and then produce larvae directly after development. The larvae of the pea weevil usually grow inside the pea grain and pupate inside the pea grain when development is complete.

The adult pea weevil can live up to 1~2 months and has the habit of mating and laying eggs several times. Adult pea weevils do not need supplemental nutrition, and can mate and lay eggs continuously in sunny weather, with the amount of eggs laid generally ranging from 50 to 300. The larvae of the pea weevil generally overwinter inside the infested seeds until the following spring, when the temperature rises above 15℃, the overwintering larvae begin to continue to develop, completing the adult stage of plumage between June and July, and begin to harm peas and other crops.

In general, the marriage of pea weevils is characterized by feeding, mating and egg-laying activities in pea fields. In the adult stage of pea weevils, they can mate and lay eggs several times. The larvae of the pea weevil grow and overwinter inside the pea, begin to continue to develop when the temperature rises above 15°C, and complete the adult stage of feathering between June and July.
