What are the characteristics of the harm of big crickets on peanuts? How to prevent and cure? (1) morphological characteristics: big crickets are commonly known as big native dogs, big-headed crickets and so on. ① adult, about 41 mm long, 13 mm wide, yellow, brown, dark brown. There is a "Y"-shaped shallow groove between the compound eyes. The forechest is well developed, with obvious longitudinal grooves, peach patches on both sides and lighter color. The veins of the forewing of the female are mostly reticulate and crossed longitudinally, no transverse veins, no sound, and there is an oviposition tube at the end of the abdomen. The elbow vein of the male's forewing forms a rough contusion, and it can make sound when the two wings are rubbed and vibrated. ② ovoid, obtusely rounded at both ends, long reniform, ca. 4mm long and 1.4mm wide. The eggshell is smooth, slightly transparent, bluish gray at first birth, yellowish after birth, and yellowish before hatching. ③ nymph molted 10 times for a total of 11 years old. The nymph had no wing bud before the 7th instar. The last instar larvae are dark brown, waxy yellow on the ventral surface and about 35 mm in length. (2) occurrence regularity: big crickets usually have one generation a year. Overwintering with nymphs in soil holes. The activities were unearthed from March to May in the M year, harming peanut seedlings. The adults emerged into adults in early June, mating during the day from July to August, the spawning period was in the middle of September, and the adults died one after another after September. The nymphs began to overwintering in the middle and late November. (3) Prevention and control measures: ① poison bait. 1 part of 50% phoxim wettable powder, 5 parts of fried rice bran, mixed well, and then mixed with an appropriate amount of water into poison bait, made into soybean-sized particles, sprinkled near the hole in the evening, the worm came out of the hole at night and was poisoned after feeding. ② winter tillage to get rid of insects. After the peanuts were harvested in autumn, the overwintering larvae were turned over to death by freezing or being eaten by black after ploughing and raking for 1 or 2 times.
