作者共试验了10科22属的73种植物种子。每种各取20颗种子,分别放在盛有40毫升蒸馏水的塑料杯中,24小时后,用体视镜观察种子产生的粘质。随后将产生粘质的种子各20颗,放在20×150毫米盛有10条埃及伊蚊二龄幼虫和20毫升水的试管中,同时以不加种子而有幼虫的试管为对照。幼虫不给以饲料,以免饲料干扰试验。试验重复4次。每次试验的第3夭,观察粘附于种子上的幼虫。以后,将能粘获大量幼虫的种子继续进行试验,在试验开始和试验的3天内,在每管内给幼虫喂以微量饲料,至第7天观察幼虫死亡率。此外,为了观察现场条件对种子保留性能的影响,模拟现场条件,在每管的底部放入5克的无菌土壤和能导致幼虫
The authors tested a total of 73 plant species in 22 families of 10 families. Twenty seeds of each were taken and placed in plastic cups containing 40 ml of distilled water, respectively. Twenty-four hours later, the viscera produced by the seeds was observed with a vitreous mirror. Subsequently, 20 gummy seeds each were placed in a test tube of 20 × 150 mm containing 10 second-instar larvae of Aedes aegypti and 20 ml of water, while the test tube with larvae without seeds was used as a control. Larvae do not feed, so feed interference test. The test is repeated 4 times. On the third day of each experiment, larvae adhering to the seeds were observed. Later on, the seeds that were able to stick to a large number of larvae were continued to be tested. The larvae were fed with a trace amount of feed within each tube at the start of the experiment and within 3 days of the test, and the larval mortality was observed by the 7th day. In addition, in order to observe the effect of site conditions on seed retention performance, simulate field conditions, place 5 grams of sterile soil at the bottom of each tube,
