“…Malathion, imidacloprid, thiamethoxam, chlorpyrifos, deltamethrin, buprofezin, lufenuron and mineral oil, these products that are registered for use in green bean and other vegetables against several pests. These results were in agreement with those obtained by Mamoon-ur-Rashid et al (2011) and Karmakar and Shera (2017) who disclosed that, the use of synthetic insecticides is extremely toxic to predators such as C. carnea, Hippodemia convergens, Coccinella septempunctata L., Brumus saturalus and C. montrouzieri of mealybugs. Imidacloprid was found comparatively the most toxic to the activities of predator, C. carnea up to 10 days after application of insecticides.…”

Field studies were conducted on cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Sternorrhyncha: Coccoidea: Pseudococcidae) which infested green bean plants at Atfih distract, Giza Governorate, Egypt during two successive summer and nili seasons of 2016 and 2017. The population density, activity periods and the effects of some weather factors on P. solenopsis and its associated natural enemies were considered. The obtained results revealed that in summer season the total numbers of alive stages had one peak of activity in the 3 rd of July during the first and second seasons (2016 and 2017), successively. While, in nili season the total number of alive stages had one peak of activity in the 3 rd and the 17 th December, during the first and second seasons (2016 and 2017), respectively. The total effects of some weather factors such as maximum and minimum air temperature (°C) and relative humidity percentage (RH%) showed significantly positive relationship with the cotton mealybug population. During this study, three hymenopterous solitary endparasitoids and four predacious species were recorded. The parasitoids were Aenasius arizonensis (Girault), Anagyrus pseudococci (Girault) and Acerophagus gutierreziae Timberlake (Encyrtidae). The predacious ones were Scymnus syriacus Mars., Coccinella undecimpunctata (L.) (Coleoptera: Coccinellidae), Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and Orius laevigatus (Fiber.) (Hemiptera: Anthocoridae). In an attempt to control this insect pest specie, eight insecticides namely, mineral oil, lufenuron, chlorpyrifos, malathion, deltamethrin, buprofezin, thiamethoxam and imidacloprid were tested on P. solenopsis and its natural enemies on green bean under field conditions. The obtained results indicated that imidacloprid was the highest efficacy against P. solenopsis recording 90.71-89.17% reduction of the insect population after 21 days of application. Also imidacloprid was the highest efficacy against parasitoids and predators of the cotton mealybug. IGRs toxicants (buprofezin and lufenuron) found to be safer to the predacious insects than other tested insecticides.

The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), is a highly invasive and harmful pest. It causes considerable loss of cotton crops in China, India and Pakistan. Little is known about its bionomics since it was first recorded in Pakistan and India in 2005. Rapid spread of this pest worldwide has accelerated research on its biology, ecology and management. The P. solenopsis has a short life cycle, and optimal temperatures lead to an increase in the number of generations per year, which is a serious threat to cotton crop production. Cotton mealybug is native to the USA, although it has now spread to >43 countries. Insecticidal control is the primary and dominant practice for this pest, and its resistance to commonly used insecticides is increasing. Biocontrol agents have strong potential for the management of nymphal instar stages. We read >250 articles related to our review title and finally reviewed recent advances in the understanding of P. solenopsis biology, ecology and control approaches, aiming to highlight integrated and biological management practices of this pest.

“…Heavy infestation of the cotton mealybug may result from the absence of natural enemies of this invasive pest (Noureen et al, 2016). Parasitoids (Aslam et al, 2017;Karmakar and Shera, 2017;Joodaki et al, 2018) and predators (Arif et al, 2012;Zazycki et al, 2015;Aslam et al, 2017;Lima et al, 2018) can control this mealybug. However, chemical control, with highly toxic insecticides to natural enemies, is the main method to reduce populations of this mealybug (Huang et al, 2012; Karmakar and Shera, 2017).…”

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

The mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is a cotton pest widespread in several cotton growing regions of Brazil, particularly in the semi-arid region of southwestern Bahia. The impact of kaolin on survival, development and reproduction of P. solenopsis was evaluated in the laboratory. The experiment was developed in a completely randomized design with two treatments: immature or newly emerged adults of P. solenopsis sprayed with kaolin and fed with cotton leaf discs treated with kaolin suspension (with kaolin) (T1) and immature or newly emerged adults of P. solenopsis sprayed with distilled water and fed with cotton leaf discs treated with distilled water (without kaolin) (T2). The kaolin suspension shortens the life cycle, increases the reproductive potential and population growth of the cotton mealybug, P. solenopsis and, therefore, it should be used with caution on cotton plants in regions with a history of occurrence of this pest.
