1, the shape of the pea elephant
Small head, big mouth, dressed in gray clothes with brown spots, with flat coleoptera wings, two large moles at the tail root, short and thick figure, this is the general appearance of pea elephant.
2. Life characteristics
Every year 1 generation, adults overwinter in crevices of storage rooms, residual plants in fields, cracks in bark, loose soil and packaging. Fly to the spring pea field in the following spring to feed, mate and lay eggs. Adults need to feed on pea nectar, pollen, petals or leaves for 6-14 days before mating and laying eggs.
Eggs are generally scattered on both sides of pea English, mostly on pea English in the middle of the plant. Each female can lay 700-1000 eggs, and the spawning peak is generally in the middle and late May. The egg period is 7-9 days. After hatching, the larvae eat into the bean English, the larval stage is about 37 days, and pupate in the bean grains when they are mature. The pupation peak period is in the middle of July, and the pupation period is 8-9 days (this period is put into storage with the harvested peas).
After several days of adult emergence, when the body wall hardens, the beans are drilled out and fly to the wintering place, or overwinter in the beans without drilling out. Adults can live for about 330 days. Adults have a strong flying ability, which can reach 3-7 kilometers, and their activities are most prosperous in sunny afternoons. The starting temperature of pea weevil development is 10℃, and the effective accumulated temperature of pea weevil development is 360 days.
Entomology
Souvenirs Entomologiques, also known as Insect World, Insect Tales, Notes on Entomology or Insect Stories, is a long biological work written by Jean-Henri casimir Fabres, a French entomologist and writer, with ten volumes. 1879 the first volume was published, and 1907 the whole book was published for the first time.
This work is an insect biology book summarizing the species, characteristics, habits and marriage habits of insects, recording the real life of insects, expressing the spirituality of insects in their struggle for survival, and also recording the motivation, life ambition, knowledge background and living conditions of Fabres's obsession with insect research.
The author combines the colorful life of insects with his own life feelings, treats insects with humanity, and reveals the author's respect and love for life between the lines.
