The effect of Groundnut bud necrosis virus (GBNV) infection on the life history traits of its vector, Thrips palmi, and its feeding preference on GBNV-infected plants were studied. A significant difference was observed in the developmental period (first instar to adult) between the GBNV-infected and healthy thrips, wherein the developmental period of GBNV-infected thrips was decreased. However, there was no effect on the other parameters such as preadult mortality, adult longevity, and fecundity. Further investigation on a settling and feeding choice assay of T. palmi to GBNV-infected and healthy plants showed that T. palmi preferred GBNV-infected cowpea plants more than the healthy cowpea plants. This preference was also noticed for leaf disks from GBNV-infected cowpea, groundnut, and tomato plants.
研究了花生芽坏死病毒（GBNV）感染对其传毒介体棕榈蓟马生活史特征的影响以及棕榈蓟马对GBNV感染植物的取食偏好。观察到GBNV感染蓟马和健康蓟马在发育时期（从一龄若虫到成虫）存在显著差异，其中GBNV感染蓟马的发育时期缩短。然而，对其他参数如未成熟蓟马死亡率、成虫寿命和繁殖力没有影响。对棕榈蓟马在GBNV感染植物和健康植物上的栖息和取食选择试验的进一步研究表明，棕榈蓟马更喜欢GBNV感染的豇豆植株而非健康豇豆植株。在GBNV感染的豇豆、花生和番茄植株的叶盘上也观察到了这种偏好。
