FERRISIA VIRGATA EPUB!
In this study, we found that another hemipteran, the striped mealybug Ferrisia virgata (Cockerell) (Hemiptera: Pseudococcidae), was able to. Performance of the Striped Mealybug Ferrisia virgata Cockerell (Hemiptera: Pseudococcidae) under Variable Conditions of Temperature and. To the best of our knowledge, we are the first to report on the biology of a Brazilian population of the striped mealybug Ferrisia virgata Cockerell.

The striped mealybug is known to vector plant pathogens, a trait uncommon in mealybugs. It ferrisia virgata been reported to transmit Cocoa ferrisia virgata shoot virus, Citrus tristeza virus, and Piper yellow mottle virus Ameyaw et al. Management Back to Top Cultural Control: Early detection provides the best chance at managing mealybugs due to the vulnerability of the immature stages DreistadtFranco et al.

Carefully inspect purchased plants to avoid spreading mealybugs. Scout susceptible plants for mealybugs or masses of cottony wax.
Mealybugs can be difficult to see with the naked eye and they often reside in cryptic or hidden locations such as the ferrisia virgata of branches and undersides of leaves, which may appear distorted. If mealybugs are not apparent but an infestation is suspected, sooty mold and ant activity may also be clues to a mealybug or other honeydew-producing insect problem.
Infested plants should be isolated or removed and disposed of immediately to prevent spread. In many commercial greenhouses, highly infested plants are destroyed because such infestations are very difficult to control.
For greenhouses, commercially available insects such as the mealybug ferrisia virgata Cryptolaemus montrouzierigreen lacewings, and brown lacewings can be purchased to prevent mealybug outbreaks DreistadtFranco et al.
Outdoors, these and other ferrisia virgata present mealybug enemies can be conserved through avoidance of foliarly applied, broad-spectrum insecticides.
Another consideration when using biological control agents for mealybug management is the presence of ants. Honeydew is very attractive to ants as a source of food. Some species of ants will ferrisia virgata mealybugs ferrisia virgata predation and parasitism to protect their access to the honeydew.
If it is suspected that ants are contributing to a mealybug infestation it is recommended to use insecticide baits, traps, or granules combined with barriers like sticky tape to prevent ants from hindering predation or other mealybug control efforts Dreistadt Due to their waxy hydrophobic covering, managing mealybugs with pesticide sprays can be difficult DreistadtFranco et al.
Slide-mounted adult female Ferrisia species are easy to recognise by the presence of only one pair of cerarii, situated on the anal lobes, and the presence of enlarged tubular ducts, each with the orifice surrounded by a flat, circular, sclerotized area associated with one or more short setae.
Kaydan and Gullan provided a thorough revision of the genus Ferrisia and a morphological key to world species, including detailed morphological description, illustration and discussion of F. It has both anterior and posterior pairs of ostioles; ventral oral-collar tubular ducts of at least 2 sizes; smaller ducts present singly or in segmental clusters on body margin, only on last 2—3 abdominal segments; minute discoidal pores in sclerotised area of enlarged dorsal tubular ducts and larger ventral oral-collar tubular ducts rarely if ever touching rim of duct opening or only very rarely on ventral ducts ; discoidal pores associated with sclerotised area around orifices of dorsal enlarged tubular ducts on anterior abdomen normally not touching outer margin of sclerotised area and very rarely projecting from that margin; dorsal enlarged tubular ducts numbering ; abdominal segment VI with multilocular disc pores, usually with more than 15 in a double ferrisia virgata each anal lobe cerarius with 3 occasionally 2 enlarged conical setae; and hind coxa with translucent pores Kaydan and Gullan, The adult male has long antennae, six well developed legs, one pair of simple wings, no mouthparts, and a pair of long white wax filaments at the posterior end.
Ferrisia virgata (striped mealybug)
CIE Map revised The female is mm long, its dorsum is covered by 2 longitudinal dark stripes that can be seen through the dusty white wax. The body is devoid ferrisia virgata marginal wax filaments and cerarii ferrisia virgata for the terminal pair on the anal lobesbut it bears many long dorsal wax filaments.
The antennae are 8-segmented.
In Israel the ferrisia virgata is parthenogeneticbut abroad it may reproduce sexually, especially when living in dense colonies; each ferrisia virgata produces about 70 eggs.
Ferrisia virgata females exhibited only sexual reproduction.
