The Influence of Ecological Factors (such as Temperature and Hygrometry) on the Development of Cassava Mealybug (Phenacoccus manihoti Matile-Ferrero, Homoptera: Pseudococcidae). Phenacoccus manihoti Matile-Ferrero cassava mealybug was accidentally carried away from South America to Africa by early 70s. Since then, it has been inducing a lot of damage to cassava cultures, which cassava remains the main foodstuff in the southern Sahara inhabitant's nutrition. Being anxious to understand the depredator population evolution in the nature, we have studied the temperature and hygrometry as main ecological factors helpful to development. The temperature favours eggs hatching and reduces the duration of embryonic, larval and cycle development whereas hygrometry's action on mealybug development can be neglected. As both factors are opposite functions in the nature, mutual influence on the field can be possible. |
