The mealybug secretes honeydew, which coats leaves and fruits and causes the growth of sooty molds. A compound consisting of a hemiterpene and a monoterpene is the female-produced sex pheromone of the vine mealybug Planococcus ficus.639,640 Its structure, (S)-lavandulyl senecioate (T119), is somehow related to that of the female-produced pheromone of the comstock mealybug Pseudococcus comstocki, T99, which is the acetate of an (R)-configured nor-lavandulol. The adult female citrus mealybug is about 3 mm (0.12 in) long with a white, brownish, or pink body covered in white wax.  During this time, the male does not feed. Ants that tend the mealybugs may move them from one plant to another (Sether et al., 1998), and occasional long-distance dispersal by wind may occur. However, under cool conditions (9–20 °C), a minimum of 6 h of feeding time was necessary for P. burnerae instars to become viruliferous (Meyer et al., 2008). Figure 2. It relies on M. endobia for energy, and is even unable to reproduce without it. The structure of T119 is even closer to that of the pheromone of the passion vine mealybug Planococcus kraunliae, T120,641 and that of Planococcus minor,642 T121, which are all esters of lavandulyl derivatives and short-chain carboxylic acids. Nucleotide sequence determination indicated that it was the replicative form of a densovirus, most closely related to the virus from Periplaneta fuliginosa (smokybrown cockroach). This includes response to host- and nonhost volatiles as well as interspecific attraction and repellency. , Adult females and nymphs suck sap with their piercing mouthparts. cytogene tic characterization of the genome of planococcus citri 43 Fig. Laura Ross • Minke B.

Males spend the one or two days of their adult lives mating, and have been observed achieving copulation with up to 23 females, with an average of about nine.

However, the epidemiology of BSV remains surprisingly unclear and the role of eBSV still needs to be clarified.
