Occurrence of new species of mealybug on cotton fields in the states of Bahia and Paraíba, Brazil

Abstract

The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) has been reported occurring in several countries causing severe losses in economically important crops, including cotton.

The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) as a new menace to cotton in Egypt and its chemical control

“…1F). These findings are similar to previously recorded symptoms (Culik and Gullan 2005;Osborne 2005;Silva 2012;Ibrahim et al 2015). The cotton mealybug P. solenopsis had not been previously noted as a pest of cotton in Egypt.…”

“…This study is the first published record of cotton as a host for P. solenopsis in Egypt. This pest has been recorded as a pest of cotton in several countries such as the United States of America (Fuchs et al 1991), Pakistan (Abbas et al 2007), India (Nagrare et al 2009) and Brazil (Silva 2012).…”

The Cotton Mealybug, Phenacoccus Solenopsis Tinsley (Homoptera : Pseudococcidae) as a New Insect on Soybean Plants in Egypt and its Population Dynamic

“…The insect also, excretes large quantities of honeydew on the upper surfaces of leaves which encourages the black sooty mold growth and hinders photosynth esis process (Fig.1-B). These results are similar to previously recorded symptoms but on cotton plants (Culik and Gullan, 2005;Osborne, 2005 andSilva, 2012). However, cotton mealybugs in Egypt, was firstly recorded on weeds (Abd-Rabou et al, 2010); on tomato plants (Ibrahim et al 2015) and on cotton plants (El-Zahi et al, 2016).…”

Survival, development and reproduction of Phenacoccus solenopsis (Hemiptera: Pseudococcidae) on kaolin-treated cotton

“…In Brazil, P. solenopsis severely infests cotton plants in Southwest and mid São Francisco, Bahia State (Silva, 2012). Heavy infestation of the cotton mealybug may result from the absence of natural enemies of this invasive pest (Noureen et al, 2016).…”
