Neopamera bilobata Say (Hemiptera: Rhyparochromidae) is an insect species which has been reported in Brazil and was recently updated as important pest of strawberry. Studies with N. bilobata habit and this species density on different strawberry cultivars are still incipient. Observations of N. bilobata adults and nymphs were realized on pseudofruits, leaves and over the substrate, near to the plant or in the crown to determinate its habit. For cultivars experiments, evaluations of N. bilobata was performed observing green and mature pseudofruits of conventional and organic strawberries in four greenhouses with three cultivars (Albion, San Andreas and Monterey). Number of trichomes on strawberry pseudofruits was also quantified. N. bilobata populations were significantly higher on strawberry pseudofruits and in the plant crown or near to the plant, walking over the substrate than on leaves. N. bilobata was found in higher numbers on Monterey cultivar in organic high tunnels. For conventional system, cultivars did not affect N. bilobata numbers. Comparing the strawberry cultivars between cultivation systems, N. bilobata was presented in higher number on Albion on conventional system comparing with organic; and higher number on Monterey on organic system comparing with conventional. Discussions on the trichomes influence on N. bilobata incidence are provided. Further research could focus on monitoring and economic threshold studies and N. bilobata density on other stablished strawberry cultivars.

Neopamera bilobata Say（半翅目：Rhyparochromidae）对草莓栽培品种的习性和密度

Neopamera bilobata Say（半翅目：Rhyparochromidae）是巴西有报道的昆虫种类，最近被更新为草莓的重要害虫。对 N. bilobata 习性和该物种密度在不同草莓品种上的研究仍处于初期阶段。对 N. bilobata 成虫和若虫的观察是在假果、叶子和基质上、植物附近或树冠中实现的，以确定其习性。对于栽培品种试验，对 N. bilobata 进行了评估，观察了在四个温室中的三个栽培品种（Albion、San Andreas 和 Monterey）中常规和有机草莓的绿色和成熟假果。草莓假果上的毛状体数量也被量化。N. bilobata 种群在草莓假果和植株冠部或植株附近显着较高，在基板上行走而不是在叶子上行走。N. bilobata 在有机高隧道中的 Monterey 品种上被发现的数量更多。对于常规系统，栽培品种不影响 N. bilobata 数量。比较不同栽培系统的草莓品种，与有机系统相比，传统系统在Albion上的N. bilobata数量更多；与传统相比，有机系统上蒙特雷的数字更高。讨论了毛状体对 N. bilobata 发病率的影响。进一步的研究可以集中在其他稳定草莓品种的监测和经济阈值研究以及 N. bilobata 密度上。比较不同栽培系统的草莓品种，与有机系统相比，传统系统在Albion上的N. bilobata数量更多；与传统相比，有机系统上蒙特雷的数字更高。讨论了毛状体对 N. bilobata 发病率的影响。进一步的研究可以集中在其他稳定草莓品种的监测和经济阈值研究以及 N. bilobata 密度上。比较不同栽培系统的草莓品种，与有机系统相比，传统系统在Albion上的N. bilobata数量更多；与传统相比，有机系统上蒙特雷的数字更高。讨论了毛状体对 N. bilobata 发病率的影响。进一步的研究可以集中在其他稳定草莓品种的监测和经济阈值研究以及 N. bilobata 密度上。
