Abstract
Mealybugs comprise some of the worst pests of fruit and shade trees in many parts of the world, especially in tropical and subtropical countries. Hibiscus mealybug, Maconellicoccus hirsutus (Green) at outbreak densities can be quite extensive actually killing hibiscus and ornamental landscape planting. M. hirsutus attacks a wide variety of host plants. It attacks grapes, guava and it was recorded on the roots of some date trees, ornamental and fruit crops. In order to achieve a successful biological control in any area, searching for the well established and most efficient biological agents should be involved. The natural enemies (predators and parasitoids) showed differences of their searching characteristics in response to host plant species.
