烟田鳞翅目害虫绿色防控技术研究
|
摘要
为了提高烤烟的品质,减少烤烟生产中农药的施用量,保证烟叶安全性,试验通过杀虫灯、食诱剂、性诱剂、生物药剂等绿色防控技术的协同互作,研究其对湘南烟田小地老虎、烟青虫、斜纹夜蛾等主要鳞翅目害虫的防治效果。结果表明:采取杀虫灯、性诱剂、食诱剂、生物药剂等防治措施的协同互作模式,烟田小地老虎、烟青虫、斜纹夜蛾等害虫的防治效果较为理想,虫口基数显著降低;虽然绿色防控技术增加了成虫的诱杀成本,但同时也提高了上中等烟比例和烟叶产量产值,同时保障了烟叶的品质安全,值得在烟叶大田生产中示范推广。
In order to improve the quality of Flue-cured tobacco, reduce the dosage of pesticides in flue-cured tobacco production and ensure the safety of tobacco leaves, the synergistic effect of green control techniques such as insecticide lamp, food attractant, sex attractant and biological agent treatment effect on the main lepidoptera pests such as Heliothis assulta, Spodoptera litura and Rottemberg in tobacco fields of southern Hunan was studied. The results showed that the synergistic interaction model of insecticide lamp, sex attractant, food attractant and bio-chemical control measures could effectively control the insect pests in tobacco field, base number of Heliothis assulta, Spodoptera litura and Rottemberg decreased significantly. Although the green control technology increased the cost of trapping and killing adults, it also increased the proportion of upper and middle tobacco and the output value of tobacco leaves, and ensured the quality and safety of tobacco leaves. It is worthy of demonstration and popularization in tobacco field production.
