進入(ru)6月后(hou)，隨(sui)著氣溫快(kuai)速(su)回(hui)升(sheng)，適宜的田(tian)間(jian)及(ji)土壤溫濕(shi)度，有(you)利(li)于害(hai)蟲(chong)活動取食(shi)，預(yu)計(ji)苗期害(hai)蟲(chong)和(he)地下(xia)害(hai)蟲(chong)將迅速(su)進入(ru)危害(hai)盛(sheng)期。為此，各地要密切監測蟲(chong)情動態，及(ji)時發布防治預(yu)報，深入(ru)田(tian)間(jian)查田(tian)治蟲(chong)，廣泛宣傳，指(zhi)導農戶采取有(you)效措施控制(zhi)蟲(chong)害(hai)。
主要害蟲防治措施：
1、二條葉甲、網目沙(sha)潛、象甲、黑絨金龜子。可用(yong)3%啶蟲脒乳(ru)油50毫升/畝(mu)、48%毒死蜱乳(ru)油60毫升/畝(mu)或2.5%高效(xiao)氯(lv)氟氰菊酯水乳(ru)劑20毫升/畝(mu)，及時噴霧(wu)防治。
2、薊馬、根絨粉蚧、斑須蝽。對大豆薊馬及為害玉米苗、甜菜的斑須蝽，可選用3%啶蟲脒50毫升/畝、25%噻蟲嗪水分散劑15克/畝或2.5%高效氯氟氰菊酯水乳劑20毫升/畝噴霧防治。防治大豆根絨粉蚧，要抓住醒蟄后尚未固定為害的低齡若蟲期，每畝用75%吡蟲啉3克加48%毒(du)死蜱60毫升，于大豆子葉(xie)出(chu)土前(qian)和子葉(xie)展開后(hou)兩次施(shi)藥。
3、金(jin)針(zhen)蟲、蠐螬。可(ke)用50%辛硫磷(lin)乳油(you)500倍液或40%毒死蜱乳油(you)1500倍液灌(guan)根。
4、地老虎(hu)。可在(zai)苗期(qi)早期(qi)，割青草間隔5米(mi)堆成堆，在(zai)堆底噴(pen)灑300倍液80%敵敵畏誘(you)殺(sha)幼蟲，或放(fang)置(zhi)糖醋酒盆誘(you)殺(sha)地老虎(hu)的成蟲。
另外，利用金龜子、地老虎、蠐螬成蟲的趨光性，可于成蟲盛發期設置黑光燈（投射式殺蟲燈）進行誘殺。
