花蓟马可以吃各种大小的花粉，并且不受外刺的影响。一种蓟马无法以粘性很强的谷物为食。花费在每种花粉上的时间比例（以暴露的秒/分钟为单位）反映了已知的宿主特异性。寄主特异性蓟马可以区分寄主花粉，显然无需探测。 Kakothrips pisivorus (Westwood) 对寄主花粉的摄取率似乎高于 4 种非寄主花粉的摄取率。在实验室的笼子里，给予花粉的蓟马在 48 小时内产下的卵明显多于给予其他花组织或不给予食物的卵。在有花粉的情况下，K. pisivorus 和角蓟马 (Haliday) 在 48 小时内产下的卵也明显多于没有花粉的情况。在花粉饮食之间的比较中，多面性的 T. fuscipennis 与每种花粉产下的卵数量相似，但 K. pisivorus 和 C. ericae 与各自的寄主花粉产下的卵明显更多。花粉饮食之间产卵率的差异反映了取食时间比例的差异。
Flower thrips could feed on pollen of a wide range of sizes and were unaffected by exine spines. One species of thrips was unable to feed on very adhesive grains. The proportion of time spent feeding on each species of pollen (in seconds/minute of exposure) reflected the known host specificities. Host-specific thrips could distinguish their host pollen, apparently without probing. Kakothrips pisivorus (Westwood) appeared to have a higher rate of ingestion of a host pollen than of 4 non-host pollens. In cages in the laboratory, Thrips fuscipennis Haliday laid significantly more eggs over 48 h when given pollen than when given other floral tissues or no food. K. pisivorus and Ceratothrips ericae (Haliday) also laid significantly more eggs > 48 h in the presence of pollen than in its absence. In comparisons between pollen diets, T. fuscipennis, a generalist, laid similar numbers of eggs with each species of pollen, but K. pisivorus and C. ericae laid significantly more eggs with their respective host pollens. The differences in oviposition rate between pollen diets reflected the differences in the proportion of time spent feeding.
