The polyphagous predatory bug Poppius (Heteroptera: Anthocoridae) is an active predator used to control many insect pests of agricultural crops. species are significantly affected by the type of food and temperature.
A study of feeding on L. (Lepidoptera: Plutellidae) eggs in climate chambers at 28 and 32 °C, 70 ± 5% relative humidity, 16:8 photoperiod, was conducted to determine the effects of different temperatures on the predation activity, biological characteristics and demographic parameters of . Twosex-MS Charts were used to determine the age-stages and characteristics of this species.
The results showed that the daily consumption of pre-adults on eggs of was highest at 28 °C, and at this temperature, there was a greater probability that would survive to adulthood (42.5%) than at 32 °C (25.0%). It has also been found that at 28 °C there was a long oviposition period (9.38 days) and the greatest female fecundity (44.2 eggs/female) In addition to the highest life expectancy of (16.96 days) at 28 °C, the intrinsic rate of increase (0.087 d) was also highest. According to our results, has the potential to grow and develop on the eggs of at 28 °C and, therefore, could potentially be used as a biological control agent in integrated pest management (IPM) programs.
多食性捕食性盲蝽 Poppius（半翅目：盲蝽科）是一种活跃的捕食者，用于控制许多农业作物的害虫。该物种的捕食活动受到食物类型和温度的显著影响。
在 28 和 32°C、70±5%相对湿度、16:8 光照周期的气候室内研究了对 L.（鳞翅目：小菜蛾科）卵的取食，以确定不同温度对捕食活动、生物学特性和 Poppius 种群参数的影响。双性 MS 图表用于确定该物种的龄期和特征。
结果表明，28°C 时，预成虫对 的卵的日消耗量最高，并且在该温度下， 存活到成虫的可能性（42.5%）大于 32°C（25.0%）。还发现，在 28°C 时，产卵期较长（9.38 天），雌虫的最大产卵量（44.2 个/雌虫）。除了 28°C 时的最高预期寿命（16.96 天）外，内禀增长率（0.087 d）也最高。根据我们的结果， 在 28°C 下有可能在 L.的卵上生长和发育，因此，它有可能在综合虫害管理（IPM）计划中用作生物防治剂。
