A Review of the Association of Ants with Mealybug Wilt.
Mealybug wilt of pineapple (MWP) is a disease of pineapple that has a long history in Hawaii, but is present throughout the world where pineapples are grown in tropical regions. The disease has an interesting etiology that is poorly understood but involves an association with virus particles, mealybug vectors, and ants which spread the mealybug vectors.
The cocoa mealybug, Exallomochlus hispidus Morrison (Hemiptera: Pseudococcidae) is known to attack mangosteen, an important fruit export commodity for Indonesia. The mealybug is polyphagous, so alternative host plants can serve as a source of nourishment. This study aimed to record the bionomics of E. hispidus on mangosteen (Garcinia mangostana L.) and three alternative hosts, kabocha squash.
After analyze the insects, was possible to associate it to the species Dysmicoccus brevipes Cockerell, due to: the morphology of the body, mouthparts, antennae segments, presence of translucent.
Wilt of pineapple caused by Pseudococcus brevipes(Dysmicoccus brevipes), Ckll., which is the most serious cause of destruction of these fruits in Hawaii (cf. R.A.E., A, xix, 676), assumes various forms. Quick wilt develops after a sudden attack by a fairly large colony of mealybugs, which may, however, feed for only a short time. Slow wilt is the result of a continuous attack by a gradually.
The establishment of the pineapple mealybug Dysmicoccus brevipes (Hemiptera: Pseudococcidae) in Italy is reported in this paper. The different instars of the mealybug found during winter in Sicily.
Develop comprehensive identification and classification systems and predictive phylogenies for each of the following groups (specifically Dysmicoccus bispinosus group of mealybugs of scale insects, Diuraphis and Hyalopterus aphids, invasive aphids of America, North of Mexico, Leptothrips and related genera, thrips commonly encounted at U.S.
