Abstract Our article documents the presence of Aedes albopictus (Skuse) from urban and rural locations in the lower Himalaya Mountains, northern Pakistan. Larvae were collected from graveyards, junkyards, plant nurseries, parks, and houses. Used tires, bird drinking pots, and water storage containers were the most common containers used by this mosquito. In the absence of Aedes aegypti (L.) (Diptera: Culicidae), Ae. albopictus appears to be the primary vector of recent dengue virus outbreaks.

Abstract Background In El Salvador, Aedes aegypti mosquitoes transmitting Zika and other arboviruses use water storage containers as important oviposition sites. Promotion of water storage container cleaning is a key element of prevention programs. We explored community perceptions surrounding cleaning practices among pregnant women, male partners of pregnant women, and women likely to become pregnant. Methods Researchers conducted 11 focus groups and 12 in-depth interviews which included individual elicitations of Zika prevention measures practiced in the community. Focus group participants rated 18 images depicting Zika-related behaviors according to effectiveness and feasibility in the community context, discussed influencing determinants, voted on community intentions to perform prevention behaviors, and performed washbasin cleaning simulations. In-depth interviews with male partners of pregnant women used projective techniques with images to explore their perceptions on a subset of Zika prevention behaviors. Results General cleaning of the home, to ensure a healthy environment, was a strong community norm. In this context, participants gave water storage container cleaning a high rating, for both its effectiveness and feasibility. Participants were convinced that they cleaned their water storage containers effectively against Zika, but their actual skills were inadequate to destroy Aedes aegypti eggs. A further constraint was the schedule of water availability. Even during pregnancy, male partners rarely cleaned water storage containers because water became available in homes when they were at work. Furthermore, prevailing gender norms did not foster male participation in domestic cleaning activities. Despite these factors, many men were willing to provide substantial support with cleaning when their partners were pregnant, in order to protect their family. Conclusions Behavior change programs for the prevention of Zika and other arboviruses need to improve community members’ mosquito egg destruction skills rather than perpetuate the promotion of non-specific cleaning in and around the home as effective. Egg elimination must be clearly identified as the objective of water storage container maintenance and programs should highlight the effective techniques to achieve this goal. In addition, programs must build the skills of family members who support pregnant women to maintain the frequency of effective egg destruction in all water storage containers of the home.

Effective mosquito control strategies in temporary water storage containers in community are urgently needed to reduce dengue fever and dengue hemorrhagic fever through mosquito larvae reduction without harmful to environment, ecosystems and community. For biological control of Aedes aegypti larvae, native larvivorus fish as Aplocheilus panchax were collected from Hpa-an Township, Kayin State. Mingalar Ywar Thit and Taung Nar Village were selected as test and control villages and 51 households each were randomly selected to recruit the study. Laboratory and field study were done from February 2016 to January 2017. In the laboratory, a series of laboratory experiments compared Aedes larva consuming rates of Aplocheilus panchax and Trichogaster trichopterus in different water volumes, in order to determine their potential as larva control agent in water storage containers. In the field, Aedes larvae and pupae positivity in containers were recorded in both villages. During intervention, two Aplocheilus panchax were put into all major, minor and miscellaneous containers monthly for 3 months in test area of Mingalar Ywar Thit Village. Larval and pupal indices were determined before and after intervention. Laboratory result found that one gram weight of Aplocheilus panchax consumed 463.04 3rd and 4th instar Aedes larvae within 24 hours. It was 3.727 fold higher in consuming rate than one gram of Trichogaster trichopterus against 124.24 Aedes aegypti larvae. After intervention, House Index (HI), Container Index (CI) and Breteau Index (BI) were significantly reduced from 86.27%, 59.86% and 172.55 to 1.96%, 1.36% and 3.92, respectively (P<0.05). Hundred percent reduction was found in key containers and 90% reduction was found in key premises in test area. Pupal indices were also significantly reduced. Native larvivorus fish Aplocheilux panchax is an efficient biological agent for the control of DF and DHF vector Aedes immature stages in Kayin State. The biological method is simple and cost-effective method for control of DF/DHF in community.

INTRODUCTION: Dengue is a serious public health problem worldwide, with cases reported annually in tropical and subtropical regions. Aedes aegypti (Linnaeus, 1762), the main vector of dengue, is a domiciliary species with high dispersal and survival capacities and can use various artificial containers as breeding sites. We assessed potential container breeding sites of A. aegypti in the municipality of Caxias, Maranhão, Brazil. METHODS: In the initial phase, we analyzed 900 properties in 3 neighborhoods during the dry and rainy seasons (August-October 2005 and February-April 2006, respectively). During the second sampling period, September 2006-August 2007, we used 5 assessment cycles for 300 properties in a single neighborhood. RESULTS: During the dry and rainy seasons, water-storage containers comprised 55.7% (n = 1,970) and 48.5% (n = 1,836) of the total containers inspected, and showed the highest productivity of immature A. aegypti; we found 23.7 and 106.1 individuals/container, respectively, in peridomicile sites. In intradomicile sites, water-storage containers were also the most important breeding sites with 86.4% (n = 973) and 85.6% (n = 900) of all containers and a mean of 7.9 and 108.3 individuals/container in the dry and rainy seaso-October 2006 (1,342). The highest number of positives (70) was recorded in May, mostly (94%) in storage containers. CONCLUSIONS: Storage containers are the principal and most productive A. aegypti breeding sites and are a major contributing factor to the maintenance of this vector in Caxias.
