The scientific name Perkinsiella saccharicida Kirkaldy belongs to the order Homoptera, Fly. Distributed in Guangdong, Guangxi, and Fujian.
Host sugar cane.
For cellar characteristics, the leaf juice of sugarcane can be sucked into the lower or middle part of a cluster of nymphs or nymphs, resulting in cane sugar, which can easily cause bituminous coal disease and red rot. Adults stabbed in the midrib when spawning, resulting in poor growth of the leaves, resulting in atrophy of sugar cane affecting the quality of production. Reduce production 13-26%.
The morphological characteristics of adults are divided into two types of long wings and short wings. Long-winged body length 5 - 5. 8mm, short-winged female body length 3.4mm, gray-brown, transparent wings, wing lines have black spots on the list, the middle of the front wing has dark brown patches. The hind paw of the hind foot is crescent-shaped from the lower edge, giving rise to many small teeth. The eggs are banana-shaped, with 3 to 6 capsules juxtaposed. The nymphs have light body color.
Life habits In the south of Fujian, there are 7-8 generations of generations, overlapping each other. Each generation of adult life 6-29 days, egg period 7-14 days, nymph period 17-37 days. Long-wing type spawning amount is tens of grains, short-winged type 300 grains, eggs are produced in the ribs or tender stems and sheaths in the leaves, visible spawning marks outside, covered with white waxy secretions. Long-wing type has phototaxis. The temperature and humidity are suitable, and the food is sufficient. The short-winged type has a large quantity, breeds quickly, and has serious damage. Natural enemies include dragonfly wasps, black-shouldered lupines, etc.
Control methods (1) Anti-resistant (resistant) varieties such as Fujian 70/611, Guangdong 63/237, Fujian 69/421, F177, and 178 were selected. It is forbidden to transfer seedlings to the sugarcane planthopper area, which can effectively prevent the spread of the insects. (2) After the harvest of spring sugarcane and ratoon sugarcane, the autumn sugarcane plantation is the main source of insects in the following year. It can use 90% crystal trichlorfon 800-1000 times or 50% dichlorvos 1000-1200 times, 20% leaves. Scattered EC 150ml/667m2, 3% carbofuran granules 3kg/667m2 root application, promote the use of 25% buprofezin WP 25-30g/667m2, control effect for 30-40 days and safety to natural enemies.
The Greenhouse Film Electric Roll-Up Unit replacing traditional manual roll-up unit to reach high speed automation in revolving & releasing films and greenhouse environment, it is the new generation of greenhouse ventilation and temperature regulation facilities. Portability, output torque, output lock, wide range and precise adjustment, waterproof, dew-proof and power-saving are the key characteristics for Electric Roll-Up Unit, which is the best choice for modern daylight greenhouse applied in different climates.
