Damage and control of sunflower white star flower golden turtle

The flower apparatus in which the adults feed on sunflowers, corn, vegetables and fruit trees. When damaging corn, adults eat filaments, damage sunflower plates, and cause sunflower plates to rot. The morphological characteristics of adults are 17-24mm in length and 9-12mm in width. Oval, with bronze or bronze color luster, body surface scattered with many irregular white velvet spots. The anterior edge of the lip base is warped upward, concave, with a frame on both sides, and the outside tilts downward; the antennae are dark brown; the compound eye is prominent; the anterior chest dorsal plate has irregular white velvet spots, and the posterior edge is concave; there is a triangle between the posterior angle of the anterior thoracic dorsal plate and the anterior edge of the sheath wing, that is, the middle chest posterior side piece; the sheath wing is broad, nearly rectangular, all over the thick engraving, and the white velvet spot is mostly transversely wavy; the buttock plate is short and wide, with 3 white velvet spots arranged in a triangle on each side. Abdominal 1Mel 5 has white villi spots on both sides of the web, stout feet, white villi spots on the knees, sharp posterior lateral angles of the posterior foot basal ganglia, 3 teeth on the outer edge of the tibial segment of the forefoot, and 2 curved claws at the top of each foot tarsal. Life habits occur one generation a year. Adults began to appear in the first ten days of May, and the peak period was from June to July. Adults are active during the day, have false death, have a tendency to the taste of wine and vinegar, and have strong flying ability. they often gather to harm the flowers and corn filaments of vegetables, and lay eggs in the soil. Most of the larvae feed on spoilage and travel on their backs. Control methods (1) see the big black Gill beetle in Northeast China. (2) hang fine-mouthed bottles on sunflowers or corn or nearby trees during the initial period, use wine bottles or washed waste agricultural medicine bottles with a height of 1 Mel 1.5m, and put 3 beetles in the bottle. When the beetles in the field fly to the bottle, they crawl near the mouth of the bottle first, and then fall into the bottle. Each 667m2 can hang 40-50 beetles to kill them, with excellent results.
