This study aimed to assessment survivorship and fecundity of the vine mealybug, Planococcus ficus (Signoret) reared on different hosts (Hedra helix L., Pittosporum tobira (Thunb.) and Nerium oleander L.). The experiment was carried under laboratory conditions, life table and population parameters were structure to assessment survivorship in all stages of the vine mealybug life cycle. Results displayed that the highest mortality existed in the immature stages (nymphal stages) for all hosts were 32.02, 42.05 and 56.63 % and the total mortality were 35.89, 48 and 64.50 % on H.helix , P. tobira and N. oleander on respectively. Fertility tables showed that the net reproductive rate (R 0) of population were (105.08, 58.90 and 54.11), mean generation time (T) were (27.42, 40.33 and 43.68), innate capacity for increase (r) were (0.17, 0.10 and 0.09), finite rate of increase (λ) were (1.85, 1.11 and 1.09) and the population doubling time (D T) were within (4.08, 6.93 and 7.70 day) for three hosts on respectively. According to the results, it could be concluded that the survivorship curve of Planococcus ficus (Signoret) approach to a diagonal model curve, which reflects a humble rate of mortality through life stages and piecemeal decreasing when oncoming adulthood with a significant effect of food preference for H.helix comparative with P. tobira and N. oleander.

“…Until now, although insecticides, different hosts and some environmental factors affecting the performance of P. solenopsis have been studied, there has been little research on metabolic mechanisms (Dhawan et al ., ; Abbas et al ., ; Sana‐Ullah et al ., ; Kumar et al ., ). EST‐related genetic resources will be helpful for analyzing gene expression.…”

The cotton mealybug, Phenacoccus solenopsis Tinsley, is a serious and invasive pest. At present, genetic resources for studying P. solenopsis are limited, and this negatively affects genetic research on the organism and, consequently, translational work to improve management of this pest. In the present study, expressed sequence tags (ESTs) were analyzed from a normalized complementary DNA library of P. solenopsis. In addition, EST-derived microsatellite loci (also known as simple sequence repeats or SSRs) were isolated and characterized. A total of 1107 high-quality ESTs were acquired from the library. Clustering and assembly analysis resulted in 785 unigenes, which were classified functionally into 23 categories according to the Gene Ontology database. Seven EST-based SSR markers were developed in this study and are expected to be useful in characterizing how this invasive species was introduced, as well as providing insights into its genetic microevolution.

“…However, they pose environmental and occupational health concerns. Recent observations that immature stages of cotton mealybugs are more vulnerable and are more likely to be affected by both biotic and abiotic factors are noteworthy due to their management implications (Kumar et al 2013). Therefore, the present study was carried out to (i) register the occurrence of the most recent invasive pest of potato crop in Egypt, P. solenopsis; (ii) to assess the effectiveness of different synesthetic insecticides on infested potato plants under field conditions; and (iii) to determine the length of time the applied insecticides are effective.…”

The cotton mealybug, Phenacoccus solenopsis (Tinsley) (Hemiptera: Pseudococcidae), has become a widespread pest causing serious losses in several economically important crops, articularly cotton. To the best of our knowledge this is the first record of cotton mealybug, P. solenopsis as a new pest of potato plants in Egypt. The insect was noticed on potato plants for the first time during the growing season of 2016 (mid-August 2016). Mealybug specimens were collected from infested potato plants and identified as P. solenopsis. In an attempt to control this insect pest species, seven insecticides viz. sulfoxaflor, abamectin + thiamethoxam, spirotetramat, thiamethoxam, imidacloprid, buprofezin, and pymetrozine, belonging to different chemical groups, were tested for their effect against nymphs and adult females of P. solenopsis on potato under field conditions. The obtained results indicated that sulfoxaflor, abamectin + thiamethoxam and spirotetramat had the highest efficacy against P. solenopsis recording 80.3-96.05% reduction of the insect population after 21 days of application. Thiamethoxam, imidacloprid, buprofezin and pymetrozine failed to exhibit sufficient P. solenopsis control.
