ossible only by combining the disciplines and techniques of biology and chemistry. For a biologist, it is difficult to understand the time frames of analytical and synthetic chemistry. A compound may take days to characterize and be available in minutes from a bottle on the shelf, or it may take ye黄油没有 发表于 2025-3-22 01:34:08
Lure and kill from the population. This technique has been variously descried as ‘lure and kill’, ‘attracticide’ or ‘attraction-annihilation’ (.), though the latter concept would also include mass trapping as described in Chapter 10.阻止 发表于 2025-3-22 05:54:26

Other uses of semiochemicalsfunction from lepidopteran sex pheromones. Only a few examples will be offered in this chapter but as time goes on new analytical breakthroughs will produce even more varieties of semiochemicals which will find new uses in IPM.吹牛者 发表于 2025-3-23 08:17:08
