Life table parameters of cotton mealybug, Phenacoccus solenopsis Tinsley, 1898 (Hemiptera: Pseudococcidae) on four different plants

Abstract

Cotton mealybug is one of the most widespread invasive mealybug species and causes economically serious damage to vegetables, ornamentals and other agricultural crops. This study was conducted between 2018-2019 in Çukurova University, Faculty of Agriculture, Department of Plant Protection, Nedim Uygun Biological Control laboratory for the determination life table parameters of Phenacoccus solenopsis Tinsley, 1898 (Hemiptera: Pseudococcidae) on four host plants (cotton, eggplant, pepper and tomato). This study conducted in climate cabinets at 25±2ºC, 60±10% RH and 16:8 h L:D photoperiod. Thirty replicates (individual insects) were used for each host plant. Petri dishes (6 cm diameter) were used for these experiments. Eggplant was determined as the most suitable host plant, with highest values of life table parameters (R0=184 nymphs/female, rm=0.269/d, λ=1.31/d, GRR=264 nymphs/female) were obtained with eggplant.

Determining some biological parameters of Aenasius arizonensis (Girault) (Hymenoptera: Encyrtidae) on cotton mealybug and the rate of parasitism in field conditions

“…Due to insufficient control strategies, P.solenopsis, cotton mealybug, cause economically important damages (30 -80%) on cotton in India (Nalwar et al, 2009). Keeping its damage potential and wide host range in mind, other researchers have determined biology of this mealybug at different temperatures and on 3 different host plants (Fand et al, 2011;Wang et al, 2012;Kumar et al, 2013;Çalışkan-Keçe, 2019).…”
