What causes Oriental mole cricketosis? What are the dangers of celery?

African adults are about 35 mm long and grayish-brown in color. The abdomen is lighter in color than the back, and the whole body is covered with fine hairs, cone heads, and tentacle filaments. The dorsal plate of the anterior thorax represents difficulty, with a distinct dimple in the shape of a long heart in dark red.

The forewings are short, grayish-brown only to the middle of the abdomen. The hindwings are fan-shaped, longer than the forewings, and extend beyond the end of the abdomen. A pair of tail beards grow at the end of the abdomen, the front paws are tungsten digging holes (digging holes), and the hind foot segments are 4 streets long on the back medial side.

The North China adult is larger than the African body, about 50 mm long, tan in color, and only some distance from the posterior medial side of the hind foot segment. The heart-shaped depression of the dorsal plate of the anterior thorax is not obvious. The egg is oval, about mm in length, shiny yellowish-white when the egg is first laid, and turns tan in about 2 4 hours, and after the egg appears dark brown, it indicates that it has entered the hatching stage.

Nymphs: Horse-old nymphs are about 25 mm long. The newly hatched insect is slow-moving, about 4 mm long, milky white, and red in the abdomen.

After 6 to 8 hours of freshly hatched nymphs, the body will turn light in color, and after 2 to 3 years, the body color will become darker until it is close to the adult. Common name lobster, morphological characteristics North China lobster: adult body length 36 50 mm, yellow-brown (female large male), light color abdomen, covered with brown hair, dark brown head, dark red spots on the bottom plate of the forethorax **, forewings 14 16 mm long, covering the abdomen front foot digging out feet, hind foot segment posterior medial side 0 2 spines, most of them 1.

Harms almost all crops, vegetables, etc. The largest losses in China are the North China earthworm and the Oriental earthworm, which are multi-eating underground pests that bite the underground roots and seeds of crops. Earthworms often bite plants or perform surface activities in a haphazard manner, opening tunnels that prevent seeds, shoots, roots, and soil from germinating or growing, thus withering and dying.

This leads to a lack of cliffs or a withering of the plant, which stops developing. It takes about 3 years to 1 generation, and adults and nymphs can enter the soil for about 70 mm after wintering in the soil. In the spring of the following year, when activities began, a loosening tunnel of about 10 mm was formed on the surface, and it was a favorable period for alluvial investigation, and April was the peak season for the disaster, and the second peak of the disaster was in late September.

Late autumn overwinters with medicinal insects. If the insects are scattered in the third instar and are damaged, this cycle will emerge into adults in August of the third year, entering the same month of the month. Its feeding habits are very mixed, and the moat is in spring and autumn.

Most of them are 1 2 years old, and the adults overwinter under the soil 30 to 70 mm. In March of this year, the overwintering insects begin to move, forming loose mounds, i.e. tunnels, on the ground, and in April the peak of the losses occurs, and vertical and horizontal tunnels may appear on the ground. The bug began to spread out after three days of hatching, and a second infested peak formed in the fall, which became a period of gluttony on the autumn crops.

In late autumn and winter, adults emerge and become adults and can overwinter at the same time.

It is likely that the vegetation has been infested by organisms, or that pest infestations have not been prevented in time. This is very harmful to celery, first of all, it will lead to a reduction in celery production, and it will also cause the leaves of celery to wither and yellow.

Oriental mole crickets occur in the northern region in 2 years for 1 generation, and in the south for 1 generation in 1 year. It is produced by adults or nymphs overwintering underground. The adults and nymphs of Oriental mole crickets are active in the soil, feeding on the sown seeds and young shoots or biting off the seedlings, which mainly harms the celery seeds and seedlings, seriously affects the quality and yield of celery, and reduces the planting efficiency of farmers.

Oriental mole crickets, also known as lala crickets, ground crickets, soil dogs, ground dogs, etc., mainly harm vegetables and seeds and seedlings sown by various crops. The adults and nymphs of the Oriental mole cricket are active in the soil, feeding on the sown seeds, young shoots or biting off the seedlings, the damaged roots are messy, and the activities of the mole cricket will make the soil topsoil into many tunnels, so that the seedling roots are threshed and the soil loses water and dies, and in serious cases, it causes the lack of seedlings and broken ridges.

It is because of some pests and diseases, and the summer is also hotter, and the pests and diseases are easy to reproduce faster, so they will be generated, which will reduce the sales of celery, and the quality of celery will be particularly bad.
