  A systemic tree injection tube was designed to introduce the required volumes of neem-based bioinsecticides into conifer trees. The device consists of plastic tubing attached with hose clamps to a maple sap spile at one end and a tubeless automobile tire valve at the other end. A hole is drilled in the tree, the spile is hammered into the hole, the device is filled with the systemic insecticide, and the system is pressurized by attaching a bicycle pump to the tire valve. The parts are readily available, the device is simple to construct and easy and quick to install on a tree, application volumes are adjustable, and the device is reusable. This device has been used successfully to inject 188 trees representing four conifer species in either spring or fall, primarily with neem formulations but also with dimethoate, imidacloprid, and acephate. In most cases, all of the material was injected into the trees without leakage, although neem formulations were characteristically slow to enter the trees and certain neem formulations were not injected completely at volumes above 15 mL per injection tube. Dosages of 0.2 g azadirachtin/cm of diameter at breast height (dbh) or less provided control of pine false webworm, spruce budworm, cedar leafminers, gypsy moth, and introduced pine sawfly on red pine, white spruce, eastern white cedar, white pine, and white pine, respectively. Dosages as low as 0.005 g active ingredient/cm of dbh applied with injection tubes in either one or two holes per tree resulted in a 95% reduction in defoliation of mature (mean dbh ± SD = 23.4 ± 3.3 cm) red pine caused by pine false webworm.

  摘要 设计了一种系统性树木注射管，用于将所需剂量的楝树生物杀虫剂注入针叶树中。该装置由塑料管组成，一端用软管夹固定在枫树树液瓶上，另一端固定在无内胎的汽车轮胎气门上。在树上钻一个洞，将树液锤打入洞中，在装置中注入系统性杀虫剂，然后在轮胎阀门上安装一个自行车打气筒，对系统进行加压。部件容易获得，装置构造简单，在树上安装方便快捷，施药量可调，装置可重复使用。该装置已成功用于在春季或秋季为 188 棵树注射四种针叶树，主要是使用印楝制剂，但也使用了乐果、吡虫啉和蚜螨特。在大多数情况下，虽然印楝制剂进入树木的速度通常较慢，而且某些印楝制剂在每支注射管的注射量超过 15 毫升时无法完全注入，但所有材料都注入了树木而没有泄漏。0.2 克氮唑/厘米胸径（dbh）或更低的剂量可分别控制红松、白云杉、东部白雪松、白松和白松上的松材线虫、云杉芽虫、雪松潜叶蛾、吉普赛夜蛾和引进的松锯螨。用注射管在每棵树上注射一孔或两孔低至 0.005 克活性成分/厘米树干的剂量，可使松材线虫引起的成熟红松（平均树干直径 ± SD = 23.4 ± 3.3 厘米）落叶率降低 95%。
