CO1-based DNA barcoding for assessing diversity of Pteropus giganteus from the state of Azad Jammu Kashmir, Pakistan / Código de barras de DNA à base de CO1 para avaliar a diversidade de Pteropus giganteus do estado de Azad Jammu e Caxemira, Paquistão

The flying fox (Pteropus giganteus) also familiar with the name of the greater Indian fruit Bat belongs to the order Chiroptera and family Pteropodidae. Current research emphasis on the DNA barcoding of P. giganteus in Azad Jammu Kashmir. Bat sequences were amplified and PCR products were sequenced and examined by bioinformatics software. Congeneric and conspecific, nucleotide composition and K2P nucleotide deviation, haplotype diversity and the number of haplotypes were estimated. The analysis showed that all of the five studied samples of P. giganteus had low G contents (G 19.8%) than C (27.8%), A (25.1%) and T (27.3%) contents. The calculated haplotype diversity was 0.60% and the mean intraspecific K2P distance was 0.001% having a high number of transitional substitutions. The study suggested that P. giganteus (R=0.00) do not deviate from the neutral evolution. It was determined from the conclusion that this mtDNA gene is a better marker for identification of Bat species than nuclear genes due to its distinctive characteristics and may serve as a landmark for the identification of interconnected species at the molecular level and in the determination of population genetics.(AU)

Effects of temephos resistance on life history traits of Aedes albopictus (Skuse) (Diptera: Culicidae), a vector of arboviruses

Abstract The effects of temephos resistance on the fitness cost of the wild populations of Aedes albopictus was evaluated. The larvae of two wild populations were exposed to the diagnostic dose of 0.02 mg and 0.012 mg/L. The larvae which survived after the 24 h exposure to diagnostic dose were considered as resistant and F1 generations were chosen for the comparisons of fitness parameters with the control strain, which includes larval developmental time, adult longevity, fecundity, wing length and hatchability. We found that temephos resistance had negative effects on larval developmental time which was longer for Gelugor strain among the populations with the median range of 10 days and a shorter longevity was observed with the median range of 13 days for males and 16 days for females. Whereas, an effective reduction of 29.8 and 38.6% was observed in fertility and fecundity of Gelugor strain as compared to control strain. In contrast, no clear differences were found in biological parameters of Balik Palau and USM strain, except fecundity and fertility with a reduction of 13.4 and 15.5%, respectively. Whereas, no significant differences were seen in the wing size between the populations with the mean length (mm) of 2.40 for Gelugor, 2.44 for Balik Palau and 2.46 for USM control (p > 0.05). Present results indicated that the temephos resistance is associated with the developmental and reproduction potential of resistant population of A. albopictus and the fitness has been compromised.
