Abstract:The scale mealybug, Diaspis echinocacti (Bouché, 1833) (Hemiptera: Diaspididae), is one of the main pests of the cactus pear in Brazil. The objective was to study biological aspects of D. echinocacti at the constant temperatures of 25, 28, 30, 33 and 35 °C with relative humidity of 60 ± 10% and photoperiod of 12 hours in the laboratory on the cactus pear cultivar, “Orelha de Elefante Mexicana”, Opuntia stricta [Haw.] Haw. The development period (22 to 35 days) and survival in the egg (92 to 100%) and nymph (21… Show more
