effeCTs Of TemperaTure and reLaTive HumidiTy On THe Life TabLe Of Phenacoccus solenoPsis TinsLey (HemipTera: pseudOCOCCidae) On COTTOn
Phenacoccus solenopsis, the cotton mealy bug, has emerged as a serious pest of cotton in india, necessitating basic studies on its development and survival at different temperatures (20, 25, 30 and 35 °C) and relative humidities (rH) (65, 75 and 85 ± 1 %) levels to ascertain optimal population growth. a life table was constructed using temperature and humidity. The nymphal duration was 20.2 d a...
متن کاملBioclimatic Thresholds, Thermal Constants and Survival of Mealybug, Phenacoccus solenopsis (Hemiptera: Pseudococcidae) in Response to Constant Temperatures on Hibiscus
Temperature-driven development and survival rates of the mealybug, Phenacoccussolenopsis Tinsley (Hemiptera: Pseudococcidae) were examined at nine constant temperatures (15, 20, 25, 27, 30, 32, 35 and 40°C) on hibiscus (Hibiscusrosa -sinensis L.). Crawlers successfully completed development to adult stage between 15 and 35°C, although their survival was affected at low temperatures. Two linear ...

شپشک آردآلود Phenacoccus solenopsis Tinsley در تاریخ 12/10/1387 از بندرعباس و میناب در استان هرمزگان از روی ختمی چینی Hibiscus rosa-sinensis جمع‌آوری شد. این شپشک که برای اولین بار از ایران گزارش می‌شود، در پاکستان و هند یکی از آفات خسارت‌زا روی محصول پنبه است و سالانه مبالغ هنگفتی صرف کنترل شیمیایی آن می‌گردد. این شپشک خسارت قابل ملاحظه‌ای به گیاهان زینتی در شهرها و درختان میوه، به‌ویژه مرکبات...
متن کاملMolecular Characterization of Two Fatty Acyl-CoA Reductase Genes From Phenacoccus solenopsis (Hemiptera: Pseudococcidae)
Fatty acyl-CoA reductases (FARs) are key enzymes involved in fatty alcohol synthesis. Here, we cloned and characterized full-length cDNAs of two FAR genes from the cotton mealybug, Phenacoccus solenopsis. The results showed PsFAR I and PsFAR II cDNAs were 1,584 bp and 1,515 bp in length respectively. Both PsFAR I and PsFAR II were predicted to be located in the endoplasmic reticulum by Euk-mPLo...
متن کاملPhenotypic variation and identification of Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) in China.
Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is an invasive mealybug that seriously damages cotton and other important crops. In previous studies in China, the presence of two submedian longitudinal lines of pigmented spots on the dorsum of adult females frequently has been used to identify this species. However, the present study records the occasional absence of pigmented spots ...
