性诱芯是利用人工合成的性外雌性激素浸入天然橡皮芯中,在棉铃虫成虫始盛期,设置诱扑器投放大田,引诱雄蛾自投落网。 该芯诱扑器极简单,在棉田设三根支架,上放一30公分直径水盆,盆里加净水和少许洗衣粉,诱芯用细铁丝穿住,小头向上,棚放之水盆之上,使诱芯在水盆中央,距水面一公分,诱芯放出雌性激素,晚上诱集雄蛾自投落水,被洗衣粉粘着淹死,每天捞蛾加水,10天换一次水,每三亩棉田放一芯,每芯坚持一代。 一、试验示范效果 Sexually induced core is the use of synthetic extra-estrogen soaked in natural rubber core, in the initial stage of the adult cotton bollworm, set the trigger placed in the field, to induce male moth self-drop network. The core device very simple trap, set up three brackets in the cotton field, put a 30 cm diameter basin, add water and a little basin detergent, induced core with fine wire to wear live, small head up, shed put the basin , The induced core in the basin, a centimeter from the surface of the water, induced by the release of estrogen inducing male moth at night since the fall into the water, was drowned by the adhesion of laundry detergent, water moths every day, 10 days for a change of water, every three M acre put a cotton field, each core uphold generation. First, the pilot demonstration effect
