Abstract

Tuta absoluta (Meyrick) is a cosmopolitan pest that affects leaves and fruits, causing damage to crops. Various control techniques are used to eliminate adults and larvae; however, none of themis completely effective. Thus, this study tested the use of a light trap with an ultraviolet lamp and an electrical device to control T. absoluta in a tomato greenhouse (‘Grazianni’) located in Paty do Alferes (Brazil) and recorded the best capture period. For this, three FIX model mosquito traps were placed inside the greenhouse (2.4 m high, 1.2 m apart) during one lunar cycle. The catch was evaluated in the following time periods: from 7:00 pm to 10:30 pm, from 10:30 pm to 02:00 am, and from 02:00 to 05:30 am. A total of 6,886 specimens were collected. The time interval from 7:00-10:30 pm resulted in the highest abundance captured (54.3%), similar to previous data on the flight period of T. absoluta. These results contribute to the Integrated Pest Management of the tomato crop, an alternative to the exclusive use of chemical control methods which fail to efficiently control the tomato moth.

灭蚊灯诱法捕获绝色夜蛾(鳞翅目:蠓科)的效果研究

Tuta absoluta (Meyrick饰)是一种世界性的害虫，影响树叶和水果，对农作物造成损害。采用各种防治技术消灭成虫和幼虫;然而，没有一个是完全有效的。因此，本研究在巴西阿尔弗雷斯(partido Alferes)的一个番茄温室(“Grazianni”)中测试了使用带有紫外线灯和电子装置的捕光器来控制绝对白蝽，并记录了最佳捕获期。为此，在一个月球周期内，在温室内放置了三个FIX模型的捕蚊器(高2.4米，间隔1.2米)。在以下时间段对渔获量进行评估:晚上7:00至10:30，晚上10:30至凌晨02:00，凌晨02:00至05:30。共采集标本6886份。在晚上7 ~ 10时30分捕获的丰度最高(54.3%)，与以往关于绝棉田鼠飞行期的数据相似。这些结果有助于番茄作物病虫害综合治理，替代化学防治方法不能有效控制番茄蛾。
