Description of adult and immature females of six mealybug species (Hemiptera: Pseudococcidae) found on citrus in South Africa Article (PDF Available) in African Entomology 13(2) In the field, the red to brown bodies of these species are covered with a fine, white wax. Due to their body coloration, Palmicultor mealybugs may superficially resemble pink hibiscus mealybug. Specimens must be slide-mounted in order to confirm genus and species-level identification.
Adult females are oval with yellowish orange bodies and yellow wax. Pyramid-shaped wax tufts surround the body. Comstock mealybug, Pseudococcus comstocki Identification tip: The Comstock mealybug primarily occurs on lemons in the San Joaquin Valley and has a thicker wax cover than the citrus mealybug. In addition, it has two spines at the. A few mealybug species feed on roots. While adult females are wingless and similar in shape to nymphs, adult male mealybugs, which are rarely seen, are tiny two-winged insects with two long tail filaments. Many mealybug species can reproduce asexually without mating. Life cycles vary somewhat by species.
Slide mounting is necessary for a more definitive identification. Several resources are available for field identification information (2,4,5,6,8). As males are rarely seen in the field and the immature or crawler stages of several mealybug species are difficult to differentiate from each other, identification focuses on the adult female. insect is grape mealybug (Figure II); if it is clear, then it is obscure mealybug (Figure III). VINE MEALYBUG: The body shape of the immature and adult female vine mealybug is oblong (Figure I, left); wider at the center of the body as compared to the anterior and pos-terior ends. The hairs surrounding the body are short in comparison to.
Vine Mealybug Look-a-like. The solanum mealybug (Phenacoccus solani) occurs in Sonoma County and closely resembles the vine mealybug. This mealybug is generally found on the crown and roots of weeds. Malva (cheeseweed) is a common host in Sonoma County. The solanum mealybug has also been documented on a wide variety of plants throughout North. The longtailed mealybug, Pseudococcus longispinus (Targioni Tozzetti), is a widely-distributed pest that feeds on many economically important hosts, particularly tropical fruits and ornamentals. This mealybug gets its common name from the two long, waxy filaments protruding from the last abdominal segment of adult females (Figure 1). This.
