“…Chrysoperla carnea lady beetle and cotton mealybug parasitoid Aenasius bambawallae were recorded most active predators and parasitoid around the cotton potted plants. The finding are in agreement with those of Agounke, et al [15] who mentioned that the coccinellids; Chilocorus nigrita Exochomus and E. troberti and the lycaenids, Spalgis spp. as the most important among the predators on cotton mealybugs in Togo.…”

Article HistoryThe field study was conducted on at the experimental field of SALU -Khairpur during, 2016. Two hundred eggs were kept for each replication on cotton plants grown in large pots. When eggs hatched, the life table parameters such as; apparent mortality, survival fraction, mortality survivor ratio, indispensable mortality and k-value were studied. Natural enemies such as; Chrysoperla carneae, lady bird beetles, Spiders and Anasius bambawallae were found active on the potted and surrounding cotton plants in the field conditions. The total mortality in egg stage went to 19.00%. The mortality percentages of 1 st instars due to natural enemies recorded was (18.73%) while, in 2 nd instars (13.13%) mortality was recorded. The total combined mortality in 1 st and 2 nd instars was recorded (26.34%) and (15.64%), respectively. However, the mortality of 3 rd instars and pupae due to parasitoids were recorded (7.28%) with the total mortality (10.26%) and the total mortality (54.83%) in cotton potted plants was recorded. Consequently, (45.17%) of adults survived with male and female ratio as ♂1:6.52♀, respectively. The highest apparent mortality was (26.34%), indispensable mortality (96.89) and k-value (0.13) recorded in 1 st instar. The maximum survival fraction was recorded (0.90) in third instars/pupae with the total k-value generations (0.35). The study revealed that the predators and parasitoids should be encouraged in cotton field when mealybugs appear, because predators are highly voracious feeder of 1 st and 2 nd instars whereas; the parasitoid, A. bambawallae is known as main controlling natural enemy of cotton mealybug.Contribution/ Originality: This study documents over the biological parameters of cotton mealybug to check its, egg laying, mortality, survivor ratio, total life span, fecundity, fertility, different life stages, predators activity and aboitic factors with the different equations about this vigorous pest under cotton field conditions.

“…R. invadens is a serious pest of mango and other fruit trees in Africa (Agounké et al, 1988;Moore, 2004), whereas R. iceryoides has been reported on ornamental and forest trees as well (Sundararaj & Devaraj, 2010). D. mangiferae and D. stebbingi have been reported as mango pests in Pakistan (Latif, 1949(Latif, , 1961.…”

Abstract. Mango orchards in Pakistan are attacked by the scale insect, Drosicha mangiferae (Hemiptera: Monophlebidae), commonly called the "mango mealybug". This insect is univoltine, active from December through May and targets multiple host plants. We used DNA nucleotide sequences to characterize and determine the phylogenetic status of D. mangiferae. Mango mealybugs were collected from several tree species from different localities and patterns of phylogenetic and genetic diversity were examined at both nuclear (18S, ITS1) and mitochondrial (COI) genes. Phylogenetic analysis confirms that the mango mealybug belongs to the family Monophlebidae. Minor genetic differences in both the ITS1 and the COI barcode region were noted among D. mangiferae collected from different geographic localities. These genetic differences revealed the existence of two genotypes of D. mangiferae that are region specific but not host-specific.

“…In microscope slide mounts, the frontal cerarii of R. rubellus were almost always linked by sclerotized cuticle, whereas in R. invadens they were usually separated by a strip of membranous cuticle; this difference was illustrated by Williams (1989 and2004). Agounké et al 1988).…”

An island-wide survey of mealybugs (Hemiptera: Pseudococcidae) conducted in 2008/09 helped identify two species of Rastrococcus from Sri Lanka. R. invadens Williams was identified from samples collected on Plumeria sp. and Ficus arnottiana, while R. rubellus Williams was found on Plumeria sp. Although R. invadens has been recorded in Sri Lanka before, this is the first record of the oriental mealybug, R. rubellus, from the country. R. rubellus was found in mixed colonies with R. invadens; so far, the infestations have not been associated with any severe crop losses. The survey revealed that R. rubellus is confined to a limited area in Colombo District. This restricted distribution suggested that it may be a new introduction to the country. Diagnostic characters to aid recognition of R. rubellus, and details of its distribution and host range within Sri Lanka are given.
