Abstract

This study examined the associations between PM (2.5 and 10) and global DNA methylation among 100 e-waste workers and 51 non-e-waste workers serving as controls. Long interspersed nucleotide repetitive elements-1 (LINE-1) was measured by pyrosequencing. Personal PM2.5 and PM10 were measured over a 4-hour work-shift using real-time particulate monitors incorporated into a backpack. Linear regression models were used to assess the association between PM and LINE-1 DNA methylation. The concentrations of PM2.5 and PM10 were significantly higher among the e-waste workers than the controls (77.32 vs 34.88, p < 0.001 and 210.21 vs 121.92, p < 0.001, respectively). PM2.5 exposure was associated with increased LINE-1 CpG2 DNA methylation (β = 0.003; 95% CI; 0.001, 0.006; p = 0.022) but not with the average of all 4 CpG sites of LINE-1. In summary, high levels of PM2.5 exposure was associated with increased levels of global DNA methylation in a site-specific manner. [ABSTRACT FROM AUTHOR]

30. Effects of elevated temperatures on the development of immature stages of Anopheles gambiae (s.l.) mosquitoes.

Author

Agyekum, Thomas P., Arko‐Mensah, John, Botwe, Paul K., Hogarh, Jonathan N., Issah, Ibrahim, Dwomoh, Duah, Billah, Maxwell K., Dadzie, Samuel K., Robins, Thomas G., and Fobil, Julius N.

Abstract

Objective: This study investigated the effects of temperature on the development of the immature stages of Anopheles gambiae (s.l.) mosquitoes. Methods: Mosquito eggs were obtained from laboratory established colonies and reared under eight temperature regimes (25, 28, 30, 32, 34, 36, 38 and 40°C), and 80 ± 10% relative humidity. Larvae were checked daily for development to the next stage and for mortality. Pupation success, number of adults produced and sex ratio of the newly emerged adults were recorded. Larval survival was monitored every 24 h, and data were analysed using Kaplan–Meier survival analysis. Analysis of variance was used where data followed normal distribution, and a Kruskal–Wallis test where data were not normally distributed. Larval and pupal measurements were log‐transformed and analysed using ordinary least square regression with robust standard errors. Results: Increasing the temperature from 25 to 36°C decreased the development time by 10.57 days. Larval survival (X2(6) = 5353.12, p < 0.001) and the number of adults produced (X2(5) = 28.16, p < 0.001) decreased with increasing temperature. Increasing temperatures also resulted in significantly smaller larvae and pupae (p < 0.001). At higher temperatures, disproportionately more male than female mosquitoes were produced. Conclusions: Increased temperature affected different developmental stages in the life cycle of An. gambiae (s.l.) mosquitoes, from larval to adult emergence. This study contributes to the knowledge on the relationship between temperature and Anopheles mosquitoes and provides useful information for modelling vector population dynamics in the light of climate change.

38. Effects of Elevated Temperatures on the Growth and Development of Adult Anopheles gambiae (s.l.)(Diptera: Culicidae) Mosquitoes

Abstract

Higher temperatures expected in a future warmer climate could adversely affect the growth and development of mosquitoes. This study investigated the effects of elevated temperatures on longevity, gonotrophic cycle length, biting rate, fecundity, and body size of Anopheles gambiae (s.l.)(Diptera: Culicidae) mosquitoes. Anopheles gambiae (s.l.)eggs obtained from laboratory established colonies were reared under eight temperature regimes (25, 28, 30, 32, 34, 36, 38, and 40°C), and 80 ± 10% RH. All adults were allowed to feed on a 10% sugar solution soaked in cotton wool; however, some mosquitoes were provided blood meal using guinea pig. Longevity was estimated for both blood-fed and non-blood-fed mosquitoes and analyzed using the Kaplan–Meier survival analysis. One-way ANOVA was used to test the effect of temperature on gonotrophic cycle length, biting rate, and fecundity. Adult measurement data were log-transformed and analyzed using ordinary least square regression with robust standard errors. Increasing temperature significantly decreased the longevity of both blood-fed (Log-rank test; X2(4) = 904.15, P< 0.001) and non-blood-fed (Log-rank test; X2(4) = 1163.60, P< 0.001) mosquitoes. In addition, the fecundity of mosquitoes decreased significantly (ANOVA; F(2,57) = 3.46, P= 0.038) with an increase in temperature. Body size (β = 0.14, 95% CI, 0.16, 0.12, P< 0.001) and proboscis length (β = 0.13, 95% CI, 0.17, 0.09, P <0.001) significantly decreased with increasing temperature from 25 to 34°C. Increased temperatures expected in a future warmer climate could cause some unexpected effects on mosquitoes by directly influencing population dynamics and malaria transmission.
