Tenuisvalvae notata preys upon several mealybug species (Hemiptera: Pseudococcidae), a group of worldwide pests including Planococcus citri and Ferrisia dasyrilii. Although the consequences of variation in temperature for the development and reproduction of insects are generally appreciated, the consequences of potential interactions between temperature and prey for predatory insects are not. Thermal requirements and predation rates were determined for T. notata at different constant temperatures with both prey species. T. notata larvae developed to adults in experimental conditions > 18 to <38 °C. The upper thermal limit for egg hatch was 34 °C and for pupation was 33 °C. Adults reared at ≥32 °C did not lay eggs and survived less than 1 week. Prey species did not affect lower temperature thresholds or thermal constants for development from egg to adult. Furthermore, prey did not affect a number of reproductive traits, but the interaction between temperature and prey affected changes in developmental times and oviposition rate with age. Predation rate of T. notata increased as a function of temperature, and T. notata adults generally consumed more nymphs of P. citri than F. dasyrilii. These findings indicate that T. notata is well adapted to the tropical and sub‐tropical temperatures and may prove useful for the biological control of some native and non‐native mealybugs.

温度和猎物评估粉虱捕食者Tenuisvalvae notata（鞘翅目：瓢虫科）的性能

Tenuisvalvae notata捕食几种粉虱（Hemiptera：Pseudococcidae），这是一种全世界范围内的害虫，包括柠檬酸球菌和达里斯氏菌。尽管人们普遍认识到温度变化对昆虫发育和繁殖的后果，但对掠食性昆虫的温度与猎物之间潜在相互作用的后果却不甚了解。测定了两种猎物在不同的恒定温度下Nott的热需求和捕食率。诺塔山毛榉在> 18至<38°C的实验条件下，幼虫发育为成虫。卵孵化的最高温度上限为34°C，化脓的最高温度为33°C。在≥32°C饲养的成虫未产卵，存活不到1周。猎物种类不会影响从蛋到成年发育的较低温度阈值或热常数。此外，猎物并没有影响许多生殖特性，但是温度和猎物之间的相互作用影响了发育时间和产卵率随年龄的变化。的捕食率T. notata随着温度的函数，和T. notata成年人通常消耗的更若虫P.螨比F. dasyrilii。这些发现表明Nott.notata 非常适合热带和亚热带温度，并且可能被证明对某些本地和非本地粉meal的生物控制很有用。
