Survey for cotton mealybug, Phenacoccus solenopsis (Tinsley) and its natural enemies.
Mealybug was considered to be a minor pest of cotton but it emerged as a major pest in 2006-2007 in North and Central zones. Extensive field surveys conducted in cotton fields during 2007-09 in Haryana, Rajasthan and Punjab in the North zone and Madhya Pradesh, Maharashtra and Gujarat in the Central zone indicated that Phenacoccus solenopsis was the only major species of mealybug recorded on co...
متن کاملStudies on Presence of Semiochemicals from Phenacoccus Solenopsis (tinsley)
The mealybug, Phenacoccus solenopsis (Tinsley), is a serious pest in Vadodara agricultural fields in India. In an attempt to find solutions to reduce the infestation by this pest,simple behavioural bioassays were conducted under the laboratory conditions using semiochemicals obtained through n-hexane solventvolatile extract of female Phenacoccus solenopsis. Observations were made at the rate of...
متن کاملSuppression of Jasmonic Acid-Dependent Defense in Cotton Plant by the Mealybug Phenacoccus solenopsis
The solenopsis mealybug, Phenacoccus solenopsis, has been recently recognized as an aggressively invasive pest in China, and is now becoming a serious threat to the cotton industry in the country. Thus, it is necessary to investigate the molecular mechanisms employed by cotton for defending against P. solenopsis before the pest populations reach epidemic levels. Here, we examined the effects of...
متن کاملBiology of the Mealybug, Phenacoccus solenopsis on Cotton in the Laboratory
Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) has been the current topic of research for insect taxonomists and applied entomologists in India due to its invasiveness, rapid spread, morphological and biological variations and the need for establishing an effective control strategy. The biology of the mealybug P. solenopsis was studied on cotton under laboratory conditions between A...
متن کاملHomology difference analysis of invasive mealybug species Phenacoccus solenopsis Tinsley in Southern China with COI gene sequence variability
The mealybug species Phenacoccus solenopsis (P. solenopsis) has caused much agricultural damage since its recent invasion in China. However, the source of this invasion remains unclear. This study uses molecular methods to clarify the relationships among different population of P. solenopsis from China, USA, Pakistan, India, and Vietnam to determine the geographic origin of the introduction of ...
