Extract

The determination of mealybugs closely related to Pseudococcus comstocki (Kuw.) has presented considerable difficulty in the past. Green (1921, p. 189) and Hough (1925, p. 52 and 1925a, p. 13) have given details of the distinguishing features for P. comstocki (Kuw.) and P. maritimus (Ehrh.) but the grounds given for the separation of the former from other closely related species are not fully satisfactory. The representatives of this group of mealybugs are becoming more and more widely spread throughout the world and of greater economic importance yearly. A correct designation of these insects is, therefore, of particular importance not only from the point of view of quarantine legislation but also of control measures. Research work on the morphological characteristics of species closely related to Pseudococcus comstocki (Kuw.) has been carried out on very large quantities of material from different parts of the world.
