First records of two mealybug species in Brazil and new potential pests of papaya and coffee.

Culik MP, Martins Ddos S, Gullan PJ - J. Insect Sci. (2006)

Bottom Line: These are the first records of D. grassii in Brazil, from papaya (Carica papaya, Caricaceae), and from coffee (Coffea canephora, Rubiaceae).Ferrisia malvastra is also newly recorded in Brazil, where it was found on Bidens pilosa (Asteraceae).Plotococcus capixaba Kondo was found on pitanga ( Eugenia cf. pitanga, Myrtaceae) and Pseudococcus elisae on Coffea canephora , which are new host records for these mealybugs.

ABSTRACT
Five mealybug (Hemiptera: Pseudococcidae) plant pest species: Dysmicoccus grassii (Leonardi), Ferrisia malvastra (McDaniel), Ferrisia virgata (Cockerell), Phenacoccus tucumanus Granara de Willink, and Pseudococcus elisae Borchsenius are recorded for the first time in the state of Espírito Santo, Brazil. These are the first records of D. grassii in Brazil, from papaya (Carica papaya, Caricaceae), and from coffee (Coffea canephora, Rubiaceae). Ferrisia malvastra is also newly recorded in Brazil, where it was found on Bidens pilosa (Asteraceae). Ferrisia virgata was collected from an unidentified weed and Phenacoccus tucumanus from Citrus sp. (Rutaceae). Plotococcus capixaba Kondo was found on pitanga ( Eugenia cf. pitanga, Myrtaceae) and Pseudococcus elisae on Coffea canephora , which are new host records for these mealybugs.

Mentions: The present work is the first record of papaya and C. canephora as hosts for D. grassii. On C. canephora, this mealybug was found in the inflorescence. D. grassii is similar taxonomically to the species D. texensis Tinsley (also recorded as D. bispinosus Beardsley) which occurs from the Neotropics through to the southern USA on a range of hosts (Ben-Dov 2005a), including on the roots of coffee in Brazil (Williams and Granara de Willink 1992; Santa-Cecília et al. 2002). As far as we know, D. grassii has never been collected on the roots of its host plants. On C. papaya, D. grassii was only observed on fruits and other parts of the plants did not appear to be infested. The infestation of D. grassii appeared to be concentrated near the peduncle of the fruits, and yellowing and rot in the area of the peduncle of the unripe (green), mealybug infested papaya fruit also was noted. Eggs, nymphs and males as well as adult female mealybugs were observed on the infested fruit indicating the suitability of papaya as a host for this mealybug. Adult females of D. grassii, as observed in this study (Fig. 1A), are pinkish, densely covered with white, powdery wax and have 16 pairs of short, thick wax filaments (less than a quarter of the length of the body) laterally on the body and one pair of long terminal wax filaments (about half as long as the body).
