IOUs field pepper and its control of Meloidae

Zhu Si leave the shallow soil stems, bulbs. Yellow wilting leaves affected plants droop, mention can be gently pulled out and prized around the surface shows a large number of dead strains of larvae or pupae. Summer high temperature of the larvae move down, the main roots and root damage. Favorable soil moisture suitable for the reproduction of Leek maggot survival. Drought will make it to the leek roots concentrated damage was worse. 1) main features. Leek was thread-like maggot larvae, long 6 ~ 9mm, black head, carcass white, smooth surface, more pointed front end, back end a little flat. As a small adult mosquitoes, poor fly. Fear of light. Often gathered in groups, in place shortly after spawning,[link widoczny dla zalogowanych], resulting in occurrence of the field spot film, serious damage. Leek plants in the clump eggs prolific underground 3 ~ 4cm Department, Zhu Shi pseudostem and bulb, Zhang Shaowen, MA Chang-sheng, Wang Lanju, Joe Bao Jian, Department of Horticulture, Henan Agricultural University, PR 4500o2. Received Date: 2oo3 an Ol-O2 larvae like to live within the organization of moist and juicy. Generally in the wetland, loam to serious damage. 2) Control Technology. Greenhouse, greenhouses and other protected control Leek maggot, and is usually killed by larvae of the main root pouring. Winter soil warming due Koupeng larvae after awakening, first hug back to shop and go to the root of the leek leaf, clear the ground, continuous cultivation of autumn and winter after the clawed leek knife cutting head of the soil around the plant cluster 3 ~ 4cm deep, and then drench. 50% of the agents commonly used phoxim 500-600 times or 600 times 9o% crystal trichlorfon. Planted every hole. Points to be 250g liquid, ridge lines planted in the ditch beside the ridge along after watering, irrigation ditch immediately after the closure (point) to give full play to the role of the drug. . Production in protected drugs are generally open furrow irrigation and fertilizer combination, ditching (points) after each 667m by: 300kgl cake or chicken manure plus urea 3Okg, scattered in ditch (point), the seal groove and then perfusion ( points). This will also put together fertilizers kill the eggs. Sealing groove (hole) after 4 ~ 5d (days) and then check the focus of larval clawed death, if found not completely radical, reperfusion,[link widoczny dla zalogowanych], or 1 or choose another agent to increase concentration. In short the principle of complete cure. Not found by examining the survival of larvae, can be a water irrigation, dry land dig a little loose, enters the normal growth of leek.

I Qishan County, Shaanxi Province in recent years, Jiang Ma chili pepper seedbeds and interim test site found in the big field IOUs Meloidae. Coleoptera Meloidae an insect families, and adults pepper leaf and petal damage, 'and focus groups of damage, could easily lead to Seedlings Deficiency and cuts, beans, turnip class is widely distributed and a heavy damage. 1 identify characteristics of adult body length of 15-18l; roar, and the head slightly triangular, antennae dark red sections near the base, the base of a 1 on melanoma. Compound eyes and the inside is black, female head rest for the tweezers filiform antennae, the male antennae and wide flat section 3-7. Chest and abdomen are black.
