Growth
Adult Brown to black The body is yellow A white band visible on the back of the chest, between the two wings. Planthopper White Both sexes have long wings and short wings. The males have long, but only winged species. White hopper back to live at the base of the crop. Adult converted into rice during the first 30 days after planting seedlings in the first season after the White planthopper growth propagation model was less than BPH. And suck sap from rice seedlings. Species and their long wings. Then evacuated from the conversion of rice paddy before flowering. Light trap captures adult planthoppers the white number. And capture as much as possible during the full moon
egg. The eggs and the eggs of BPH. But more than a shell egg. Each female can lay 300-500 eggs in its life span of about two weeks,
the embryo. Larval stages of the hopper all the white. And can not distinguish between different types of larvae in the field. Embryo recently Planthopper White differentiate by a black and white at the top, the
destruction of
embryos and larvae of white back planthopper. Suck sap at the base of the clump of rice. Sweet and manufacturing data came out less than BPH. The black mold caused less destruction of the joint. White rice planthopper was a lot of destruction. Yellow and orange leaves Later, the leaves are brown. In the first stage, the rice was dry patches. The destruction will be expanded if the insect population increased steadily by the planthopper infestation of white rice in the stomach. After a white planthopper insect carriers of the virus to the plant management , cultural. How the action that is effective against BPH. Available with white back planthopper. As well as resistant varieties The white back planthopper outbreaks of paddy rice during pregnancy. Rice harvested early can reduce the number of propagation models hopper behind White. Rice tillering Planthopper White both adults and larvae are more rice varieties that are less costly to control biological planthopper white background with natural enemies destroy all stages of growth. In general, the population of white back planthopper was less. The use of insecticides without carefully consider the potential destruction of natural enemies hopper over the white. And the outbreak of the hopper behind White. Egg white is back planthopper parasitoid wasp parasitism by little. Rolling green or suck eggs. Or predatory mites eat Embryonic and a full day at Yongbyon by parasitoids dryinid or fungi predators of larvae and adults, including predators beneath the surface, including insects wattle beetle vertically larvae dragonflies home dragonfly pin them on the surface are. gerridae predators is important as well. Predators in these waters to catch a feed hopper fall on the surface. You can also catch on rice leaf hopper nearby. The water level is too Rove beetles and ground beetles and spiders in Maun crown. Catch larvae and adult leaf hopper back in the white rice eat dragonfly larvae needle eaten as rice leaf hopper on the island. The house dragonfly larvae eaten rice planthopper flying their control by chemical means using insecticide for aphids, white jump back as of BPH. Spraying of insecticides effective than tablets. Do not use insecticides that cause outbreaks of insects increased exploration. Explore rice planting after 30 days, then weekly until the rice flowering. Pat Rice to move the hopper and counting. Random survey of 20 white dots or diagonal swathes of paddy calculate the average number of insects per plant hopper behind the counter was white. If detected, the hopper 1/2 times a week to explore the insecticide at the base of the crop when the larvae mature than the first / early August 6. insect cigarettes in currency Leptocorisa called. aquatic insects The look of these outbreaks. Biology and destroy crops similar to a pest normal yield loss due to insect a little. Because the insect population a very certain. And breaking news is a short time. The growth of rice Insects found in aquatic environments. It is more common in rainfed and upland rice. Insects are plenty of factors that make the nearby forest. There are lots of weeds near a rice field. And the overlap time between rice grown adult. streamlined shape With long legs and antennae The body is brownish green Aquatic insects start to see outbreaks in the rainy season. Growth and propagation 1-2 model, which relies on the plant is a weed grass before migrating into the rice paddy flowering stage. When disturbed The adult fly and emit a foul odor from glands in the stomach. Adults are usually the afternoon. And early and rest on the grass while the sun. In the dry season, the adult moving into the forest. And the rest in the area. Light trap can ensnare insects things each female lays hundreds of eggs during a lifetime is about 2-3 months, the eggs are dark reddish brown. Egg-shaped plate with a lay 10-20 eggs in a row on the surface of the leaves along the midrib are 2-3 rows when the eggs hatch into larvae. Eggshell turns out half saw a hole into the embryo. Green algae include brown rice blend in with a group on a separate but leaves out to destroy the larvae and adults suck the sap sucking and endosperm of the grain of rice as well. Insects have piercing sucking mouth to suck the liquid from the mouth to make it a point to suck and hold an erection of mouth is the rub.
