摘要： Geocoris pallidipennis (Costa, 1843) (Heteroptera: Lygaeidae) is a generalist predator of insect pests and it is used in insect pest biological control. However, there has yet to be established a mass rearing protocol for this predator that using artificial diets, and therefore its field applications are limited. This study was undertaken to optimize the mass rearing of G. pallidipennis employing a microencapsulated artificial diet. We selected four types of ingredients for the diet recipes: insect body, homogenate of Rhopalosiphum maidis (Fitch, 1856); micronutrient (fish egg) homogenates; nectar source (pure honey & corn pollen); and nutritional supplements, namely soluble L-Tyrosine & yeast extract. We tested 25 combinations of the ingredients using an orthogonal test to establish the most effective factors in the ingredients, and we screened the best five combinations. The results showed that the different ingredients and their combinations significantly influenced various biological traits of G. pallidipennis. Development to sexual maturity was achieved only with five ingredient combinations.
