英文摘要	Simple Summary Cactus is an important drought-tolerant crop that has very various beneficial uses. In Morocco, cactus is a perfectly appropriate crop for land rehabilitation in the arid and semi-arid regions. With little investment, it can produce important resources for human and animal nutrition and generate adequate revenues for farmers. Unfortunately, the sustainability of this extremely resilient ecosystem has become seriously threatened by the appearance of Dactylopius opuntiae (Hemiptera: Dactylopiidae). This cochineal which is specific to cacti, was introduced in Morocco in 2014. The aim of this study was to evaluate the effect of temperature on life cycle parameters of D. opuntiae at 20, 23, 26, 32, and 40 +/- 1 degrees C, 65 +/- 5% RH, and a photoperiod of 12L:8D. Temperatures ranging from 26 degrees C to 32 degrees C were appropriate for the survival, development, and reproduction of the scale insect. Parthenogenesis in females was not observed during our study. This study also showed that D. opuntiae females required a higher thermal constant (769.23 D degrees) than males (357.14 D degrees) to grow to the mature adult stage. The effect of temperature on Dactylopius opuntiae (Cockerell) life cycle parameters was evaluated at 20, 23, 26, 32, and 40 +/- 1 degrees C, 65 +/- 5% RH, and a photoperiod of 12 L:8 D. Temperatures ranging from 26 degrees C to 32 degrees C were suitable for survival, development, and reproduction of D. opuntiae. The total developmental time of females ranged from 94.23 d (20 degrees C) to 43.55 d (40 degrees C). The average development time of males from egg to death ranged from 26.97 days at 32 degrees C to 50.75 days at 20 degrees C. The probability that a newly laid egg would survive to the adult stage was highest at 26 degrees C and 32 degrees C (44-60%). The parthenogenesis in females was not observed during our study. The longest oviposition period was observed when the cochineal was reared at 32 degrees C (17.97 days), and the highest fecundity was observed at 32 degrees C (355.29 egg/female). The highest proportion of females (0.80) was observed at 40 degrees C. According to the age-stage-two-sex life table, the highest value of the intrinsic rate of natural increase (r(m)) was recorded at 32 degrees C. The lower developmental thresholds for the total pre-adult female and male and adult female and male stages, were 10.15, 12.21, 10.54, and 21.04 degrees C, respectively. Dactylopius opuntiae females needed a higher thermal constant (769.23 D degrees) than males (357.14 D degrees) to achieve their development and reach the mature adult stage. These findings will be useful for the development of an integrated pest management strategy for D. opuntiae.
