甘薯粉虱Bemisia tabaci（半翅目：粉虱科）是一种非常多食性的害虫，在以色列和世界范围内造成重大的作物损失。B。烟粉虱是一个物种复合体，其中B和Q生物型在世界范围内分布最广，危害最大。在2008-2010年期间，监测了以色列生物型组成和杀虫剂抗性的变化，以确定与抗性爆发相关的种群动态模式。结果表明，B生物型种群占主导地位的作物生长在开放的领域，而Q生物型种群逐渐占主导地位的作物生长在保护条件下，如温室和蚊帐，其中的抗性爆发通常发展后，几个杀虫剂的应用。虽然在前几年，Q生物型种群在以色列的许多地区被广泛检测到，但在2010年期间观察到B生物型在收集的种群中占显著优势，表明B生物型的不稳定性。从一年到另一年的烟粉虱种群。B相对丰度变化动态和变化的原因。烟粉虱生物型及其抗性现状进行了讨论。
The sweetpotato whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) is an extremely polyphagous insect pest that causes significant crop losses in Israel and worldwide. B. tabaci is a species complex of which the B and Q biotypes are the most widespread and damaging worldwide. The change in biotype composition and resistance to insecticide in Israel was monitored during the years 2008-2010 to identify patterns in population dynamics that can be correlated with resistance outbreaks. The results show that B biotype populations dominate crops grown in open fields, while Q biotype populations gradually dominate crops grown in protected conditions such as greenhouses and nethouses, where resistance outbreaks usually develop after several insecticide applications. While in previous years, Q biotype populations were widely detected in many regions in Israel, significant domination of the B biotype across populations collected was observed during the year 2010, indicating the instability of the B. tabaci population from one year to another. Reasons for the changing dynamics and the shift in the relative abundance of B. tabaci biotype, and their resistance status, are discussed.
