Abstract

About 34 insect species were found infesting olive orchards in UT of J&K Among them, olive psylla, Euphyllura pakistanica; olive black scale, Saissetia olea and tinged bug, Eteoneus sp. sigilatus Drake caused serious damage. The avoidable yield losses caused by all the pest species were 33 to 53%. On the basis of various field trials conducted neem insecticidal soap (NIS @ 2.5 %) and horticultural mineral oil (HP spray oil 2% of solution) were found effective against major pests. In case of severe infestation imidacloprid (17.8 SL) a.i. 0.075 % and cartap hydrochloride 4G @ 100g/ tree resulted in their efficient suppression. As such these treatments were incorporated in grower specific IPM modules evaluated for two years. Amongst the tested modules, integrated module (M1) followed by pesticide module (M3) were found most effective. However, for resource poor farmers and non-disruptive cultural module M1 and organic growers M2 could be alternatively practiced. It was concluded that for scale and psyllids, the insecticide protection is necessary but the infestation by lace bug could be managed by non-disruptive methods.

外来橄榄中新出现的虫害问题以及查谟和克什米尔地区针对种植者的 IPM 模块

在查谟和克什米尔联邦直辖区的橄榄果园中发现了约 34 种虫害，其中橄榄蚜（Euphyllura pakistanica）、橄榄黑鳞（Saissetia olea）和绒毛虫（Eteoneus sp. sigilatus Drake）造成了严重破坏。所有害虫种类造成的可避免的产量损失为 33%至 53%。根据各种田间试验，印楝杀虫皂（NIS @ 2.5 %）和园艺矿物油（HP 喷雾油 2 % 溶液）对主要害虫有效。在虫害严重的情况下，0.075 % 的吡虫啉（17.8 SL）和 4G @ 100 克/棵的盐酸克螨特可有效抑制虫害。因此，这些处理方法被纳入种植者特定的 IPM 模块中，进行了为期两年的评估。在测试的模块中，综合模块（M1）最有效，其次是杀虫剂模块（M3）。不过，对于资源贫乏的农民和非破坏性的文化模块 M1 和有机种植者 M2 可以替代使用。结论是，对于鳞翅目和牛皮蝉，杀虫剂保护是必要的，但花边蝽的侵扰可以通过非破坏性方法进行管理。
