Abstract

The distribution of entomopathogenic nematodes applied by drip irrigation was evaluated by injecting small volumes of Steinernema carpocapsae (Weiser) All strain, Steinernema feltiae (Filipjev) SN strain, Steinernema glaseri Steiner, and Heterorhabditis bacteriophora HP 88 strain Poinar suspensions into drip irrigation lines. Additionally, Steinernema riobrave Cabanillas, Poinar, & Raulston, and S. carpocapsae were injected in a 10-liter volume of water with an injection pump. Overall, the nematodes were evenly distributed along the drip lines. The total number of nematodes recovered from drip emitters was variable ranging from 42 to 92%. However, drip irrigation lines have potential to deliver entomopathogenic nematodes efficiently into pest habitats.

摘要

通过将少量斯氏线虫属的苹果蠹蛾斯氏线虫（Weiser）All品系、斯氏线虫属的嗜菌异小杆线虫（Filipjev）SN品系、格氏斯氏线虫（Steiner）以及异小杆线虫属的嗜线虫致病杆菌（Poinar）HP 88品系悬浮液注入滴灌管线，评估了通过滴灌施用昆虫病原线虫的分布情况。此外，使用注射泵将里奥勇敢斯氏线虫（Cabanillas、Poinar和Raulston）以及苹果蠹蛾斯氏线虫注入10升水中。总体而言，线虫沿滴灌管线分布均匀。从滴头回收的线虫总数各不相同，范围在42%至92%之间。然而，滴灌管线有潜力将昆虫病原线虫高效输送到害虫栖息地。
