The phytoseiid mite, Neoseiulus longispinosus (Evans) is considered as one of the effective biological control agents against the tetranychid mites in the Indian subcontinent. This predator can be effectively utilized to manage the two-spotted spider mite, Tetranychus urticae Koch under protected conditions. Carnation holds a significantly important position as cut flower crop in India as well as throughout the world. In this study, the biology and population growth parameters of predatory mite were studied against three different stages of T. urticae on three different cultivars of carnation viz., Kleos, Bizet and Baltico. The predator was able to complete its life cycle on all the offered stages of the prey and on all the three cultivars. The results indicated that the biology was not much affected by the different cultivars. However, the cultivar Bizet was found to be slightly better for the development of the predatory mite as the maximum fecundity (62.26 eggs/female) was recorded on this cultivar. Although numerically higher fecundity was observed on Bizet, no statistically significant superiority was found. Among the different stages of prey fed to the predator i.e., egg, protonymph and deutonymph, the predator showed better biology and population growth parameters on egg stage compared to both protonymphal and deutonymphal stages of T. urticae.
植绥螨，长棘新小绥螨（埃文斯）被认为是印度次大陆防治叶螨的有效生物防治剂之一。这种捕食者可以在保护条件下有效地用于控制二斑叶螨，即叶螨科的二斑叶螨。康乃馨作为切花作物在印度以及全世界都占据着非常重要的地位。在本研究中，针对康乃馨的三个不同品种，即克莱奥斯、比才和波罗的海，研究了捕食螨在二斑叶螨三个不同阶段的生物学特性和种群增长参数。捕食者能够在猎物的所有提供阶段以及所有三个品种上完成其生命周期。结果表明，不同品种对生物学特性影响不大。然而，发现比才品种对捕食螨的发育略好，因为在该品种上记录到最高繁殖力（62.26 粒卵/雌螨）。虽然在比才品种上观察到繁殖力在数值上更高，但未发现统计学上的显著优势。在喂食捕食者的猎物的不同阶段，即卵、若螨和雌若螨中，与二斑叶螨的若螨和雌若螨阶段相比，捕食者在卵阶段表现出更好的生物学特性和种群增长参数。
