“…Lady beetle colonies were maintained in transparent Plexiglas™ cages (40 × 25 × 20 cm in length, width and height) lined on the bottom with paper towel, holding one pumpkin infested with F. dasyrilii nymphs and adults per cage as prey according to the procedures described by Barbosa et al . (). Both lady beetle and mealybugs were maintained at 25 ± 2 °C, 60 ± 10% relative humidity and photoperiod of 12:12 h (L:D).…”

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.
