Abstract

苯甲醛防治象甲类昆虫的用途，属虫害的农药防治技术领域。根据本发明，苯甲醛可以任意浓度单独或与其它药物进行任意配比后用于豆象科、象虫科、长蠹总科、谷盗科、拟步甲科几类专门在仓储过程中侵害稻谷类及豆类粮食的昆虫的防治。本发明优化的技术方案是用苯甲醛熏蒸来防治象甲类昆虫，苯甲醛熏蒸浓度为最好为16～25mg/立方米，但本发明防治方法不局限于熏蒸方式。和现有技术相比，本发明的优点是药剂更安全、有效和来源稳定。

Description

苯甲醛防治象甲类昆虫的用途
技术领域
本发明属虫害的农药防治技术领域。
技术背景
在粮食仓储过程种，象甲类昆虫如鞘翅目(Coleoptera)豆象(Bruchidae)，象虫科(Curculionidae)；蠹甲类昆虫，如鞘翅目(Coleoptera)长蠹总科(Bostrychidae)；盗谷类昆虫如鞘翅目(Coleoptera)谷盗科(Trogossitidae)，拟步甲科(Tenebrionidae)等是侵害稻谷类、豆类的主要害虫。通常用来杀灭这些昆虫的熏蒸药剂为磷化铝、磷化氢。不但随着药剂使用频次和范围的增加，昆虫会逐渐出现抗药性，而且这些药剂也不符合人们对食品安全、环境保护和技术要求越来越高的要求。进一步开发更安全，更有效和来源稳定的防治象甲类昆虫药物，是本领域研发的一个重要课题。苯甲醛是传统使用的香料添加剂，有着良好的安全性和稳定的来源。
虽然公开号为CN 1177279A的中国专利文献提到了用芳香醛对蛛形纲的蜱螨亚纲螨虫类，昆虫纲中的膜翅目，双翅目，蜚蠊目，虱目，蚤目等害虫进行控制和杀灭，但这些昆虫的共性是主要侵害对象为包括人在内的温血动物，多数为刺吸式口器、舐吸式口器，而象甲类昆虫是以侵害植物种子为主的咀嚼式口器类昆虫，两类昆虫的生理结构和药物控制杀灭机制都不同。
发明内容
本发明的目的在于提供苯甲醛防治象甲类昆虫的用途，也就是将苯甲醛用于防治象甲类昆虫。
苯甲醛(Benzaldehyde，化学式C6H5CHO)为GB 2760-2014及GB 28320-2012规定允许使用的食品用合成香料，在室温下为无色液体，具有特殊的杏仁气味，可从多种香料作物中提取，也可人工合成。
本发明的技术方案是用苯甲醛防治象甲类昆虫。根据本发明，苯甲醛可以任意浓度单独或与其它药物进行任意配比后用于豆象科、象虫科、长蠹总科、谷盗科、拟步甲科几类专门在仓储过程中侵害稻谷类及豆类粮食的昆虫的防治。本发明优化的技术方案是用苯甲醛熏蒸来防治象甲类昆虫，苯甲醛熏蒸浓度为最好为16～25mg/立方米，但本发明防治方法不局限于熏蒸方式。
以下是苯甲醛对五种昆虫的熏蒸活性。
用四个浓度的苯甲醛的熏蒸五种昆虫，校正死亡率见下表。所述四个浓度分别为4μg/L、8μg/L、16μg/L、20μg/L，熏蒸时间为12小时、24小时、48小时。
苯甲醛对五种昆虫的熏蒸校正死亡率
由上表可明显显看出，无论用那个浓度的苯甲醛熏蒸，对鞘翅目(Coleoptera)豆象科(Bruchidae)绿豆象(Callosobruchus chinensis(Linnaeus))；象虫科(Curculionidae)米象(Sitophilus oryzae(Linnaeus))；长蠹总科(Bostrychidae)烟草甲虫(Lasioderma serricorne)；谷盗科(Trogossitidae)谷盗(bark-gnawing beetle)；拟步甲科(Tenebrionidae)赤拟谷盗(Tribolium castaneum Herbst)都具有显著的杀灭效果。
和现有技术相比，本发明的优点是药剂更安全、有效和来源稳定。
具体实施方式
实施例1.
某水稻谷仓出现绿豆象、米象虫害，采用16mg/立方米浓度的苯甲醛在常温下对同样的水稻谷仓进行熏蒸每半个月1次，每次12小时，连续熏蒸4次，可有效控制绿豆象、米象虫害发生。
实施例2.
某豆类仓库出现绿豆象、赤拟谷盗虫害，采用20mg/立方米浓度的苯甲醛在常温下对同样的豆类仓库进行熏蒸每月一次，每次20小时，连续熏蒸3次，可有效控制绿豆象、赤拟谷盗虫害发生。
实施例3.
某面粉类仓库出现赤拟谷盗、谷盗、烟草甲虫虫害，采用20mg/立方米浓度的苯甲醛在常温下对同样的面粉类仓库进行熏蒸：每半个月1次，每次12小时，连续熏蒸3次，可有效控制赤拟谷盗、谷盗、烟草甲虫虫害发生。
上面对本发明的具体实施例作了具体说明，但是本发明并不限于上述实施例，在本领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种改变。
