“…On the other hand, in the control group, the number of male mosquitos was more than the number of female mosquitos. The results of this study were in line with previous studies that found mosquitoes that hatch from pupae into adults are mostly male 18 .…”

Temephos is an insecticide active ingredient often used by a community as Dengue Hemorrhagic Fever (DHF) vector control in imago. The development of Ae aegypti is influenced by biotic and abiotic factors. This study aimed at determining the effects of temephos concentration on mortality and a life level of Ae aegypti at some concentration tests.The experimental design used in this study was Complete Random Design (CRD). This study involved temephos as the active ingredient and third instar Ae. Aegypti larvae originating from Pangandaran Regency. Data analysis used an ANOVA test with 5 treatments and 5 replications. The results showed that there was any influence of concentration towards a number of mortality, a life level, morphology of larvae, pupae and imago, a number of males and females, and a number of eggs hatchability. Temephos concentration affected the mortality of third instar larvae of Ae. aegypti with temephos concentration of 0.019 ppm, 0.069 ppm, 0.105 ppm, and 0.140 ppm and affected a life level of Ae. aegypti with biological parameters.

“…gambiae mosquitoes are likely to suffer the consequences of running the risk of exposure to potential predators and human interference as observed in Aedes aegypti (Padmanabha et al, 2011). This is likely to alter the female mosquito fertility and fecundity (Zuharah et al, 2016), crucial vectorial traits necessary for survival. It is also likely to affect epidemiologically relevant mosquito disease transmission traits such as longevity or vector competence (Beldomenico and Begon, 2010;Muturi et al, 2011;Takken et al, 2013;Moller-Jacobs et al, 2014).…”

In this study an informal "after only with control" experimental design was used to evaluate the impact of ethanol and water extracts of leaf and mature green fruits of Phytolacca dodecandraon the life history of An. gambiae. Eighty milligrams of crude extracts of mature green fruits of P. dodecandra was dissolved in 100 millilitres of rain water and the solution serially diluted to concentrations of 80, 40, 20, 10, 5, and 2.5 mg/100 mL. The diluents were then added into five groups of six sets of larval rearing trays each measuring 21 cm × 15 cm × 8 cm. This was repeated for leaves of P. dodecandra, Azadirachta indica leaves, and Deltamethrin. Each tray received 100 freshly laid An. gambiae eggs. Climatic conditions within insectaries were 29°C~30°C, 70%~80% relative humidity, and 12:12, L: D photoperiod. The experiments were replicated four times. The extracts impacted the life history of exposed mosquitoes irrespective of parts of P. dodecandra used or dose. Parts of plant used impacted mortality significantly (p < 0.001) compared to dose (p > 0.05). Water extract was more potent than ethanol extracts (p < 0.05). Though toxicity reduced with time, longevity of the extracts was dose dependent and significantly influenced mortality (p < 0.001). Lethal doses (LC 50 ) were relatively lower (doses of ≤ 4.6) with small lower and upper 95% CI. It is concluded that extracts of P. dodecandra impacts the life cycle of An. gambiae mosquitoes critically interfering with their development.

“…Colonies of Ae. aegypti were subjected to a sublethal dose LC 50 [ 34 ] (where 50% of the mosquitoes could still be alive and capable of producing first-generation progeny) of MHAQ following the WHO larval bioassay method. After 24-h exposure, the surviving larvae were transferred and allowed to emerge in emergence cages.…”

Evaluation of a mosquito home system for controlling Aedes aegypti

et al. 2021

Background Dengue is a significant public health issue that is caused by Aedes spp. mosquitoes. The current vector control methods are unable to effectively reduce Aedes populations and thus fail to decrease dengue transmission. Hence, there is an urgent need for new tools and strategies to reduce dengue transmission in a wide range of settings. In this study, the Mosquito Home System (MHS) and Mosquito Home Aqua (MHAQ) formulations were assessed as commercial autodissemination traps in laboratory and small-scale field trials. Method Multiple series of laboratory and small-scale field trials were performed to assess the efficacy of MHS and MHAQ exposed to Ae. aegypti. In the laboratory trials, various parameters such as fecundity, fertility, wing size, oviposition preferences, residual effects, and MHAQ transference to other containers through controlled experiments were tested. For small-scale field trials, the efficacy of the MHS and MHAQ approaches was determined to ascertain whether wild mosquitoes could transfer the MHAQ formulation from MHS stations to ovitraps. Results The data revealed that Ae. aegypti was highly susceptible to low concentrations of MHAQ formulations and had a residual effect of up to 3 months, with MHAQ exposure affecting fecundity, fertility, and mosquito wing size. In the oviposition studies, gravid females strongly preferred the hay infusion compared to tap water and MHAQ during egg-laying in the laboratory. Nevertheless, the use of commercial MHAQ by MHS was highly attractive in field settings compared to conventional ovitraps among local Aedes spp. mosquitoes. In addition, MHAQ horizontal transfer activities in the laboratory and small-scale field trials were demonstrated through larval bioassays. These findings demonstrated the potential of MHAQ to be transferred to new containers in each study site. Conclusion This study provided proof of principle for the autodissemination of MHAQ. Through further refinement, this technique and device could become an effective oviposition trap and offer an alternative preventive tool for vector control management. Graphical abstract
