番茄，番茄属，采用电穿透图技术和完整叶片生物测定法研究了吡虫啉处理对褐花蓟马Frankliniellafusca（Hinds）和西花蓟马Frankliniellococcuentalis（Percuscans）的探测和沉降行为的影响。对于每个实验，蓟马进行未经处理的植物和植物处理的两个率的吡虫啉：7.81和41.55微克[（AI）]每株。F.与未处理的植物相比，fusca在用高比率的吡虫啉处理的植物上探测的频率较低。F.与未处理的植株相比，高剂量吡虫啉处理的植株上的fusca noningestion探测波形和摄食时间较短。相反，F.与未处理的植物相比，在用低或高的吡虫啉比率处理的植物上，occurentalis探测的时间更长，探测的频率更高。与未处理的植物相比，它们在高速率处理的植物上摄取的频率更高，持续时间更长。与未处理的植物相比，在吡虫啉处理的植物上的noningelae探测波形的持续时间和频率更大。F. occupientalis比F.在用高比率的吡虫啉处理的植物上的褐变。F. fusca比F.在未经处理的植物中的occurentalis。F. fusca和F.在选择的生物测定中，在前30分钟内，occurentalis的沉降行为不同。F. fusca喜欢在未处理植株的叶片上定居，而F.在完整的叶片选择生物测定中，occurentalis没有表现出偏好。
The effects of tomato, Lycopersicum spp., leaves treated with imidacloprid on probing and settling behavior of Frankliniella fusca (Hinds) and Frankliniella occidentalis (Pergrande) were examined using an electrical penetration graph technique and an intact leaf bioassay. For each experiment, thrips were subjected to nontreated plants and plants treated with either of two rates of imidacloprid: 7.81 and 41.55 microg [(AI)] per plant. F. fusca probed less frequently on plants treated with the high rate of imidacloprid compared with the nontreated plants. The duration of F. fusca noningestion probing waveforms and ingestion was shorter on plants treated with the high rate of imidacloprid compared with that on nontreated plants. In contrast, F. occidentalis probed longer and more frequently on plants treated with either the low or high imidacloprid rates compared with nontreated plants. They also ingested more frequently and for longer durations on plants treated with the high rate compared with nontreated plants. The duration and frequency of noningesting probing waveforms were greater on the imidacloprid-treated plants compared with the nontreated plants. F. occidentalis probed and ingested more frequently and for a longer duration than F. fusca on plants treated with the high rate of imidacloprid. F. fusca ingested more frequently and the duration of ingestion was longer than F. occidentalis in untreated plants. F. fusca and F. occidentalis settling behavior differed within the first 30 min in a choice bioassay. F. fusca preferred settling on leaves of nontreated plants, whereas F. occidentalis showed no preference in an intact leaf choice bioassay.
