Spatial Distribution and Long-Term Persistence of -Infected in the Mentari Court, Malaysia.

Dengue is endemic in Malaysia, and vector control strategies are vital to reduce dengue transmission. The strain AlbB carried by both sexes of was released in Mentari Court, a high-rise residential site, in October 2017 and stopped after 20 weeks. frequencies are still being monitored at multiple traps across this site, providing an opportunity to examine the spatiotemporal distribution of and mosquito density with respect to year, residential block, and floor, using spatial interpolation in ArcGIS, GLMs, and contingency analyses.

PesTrapp mobile app: A trap setting application for real-time entomological field and laboratory study.

Diseases such as malaria, dengue, Zika and chikungunya remain endemic in many countries. Setting and deploying traps to capture the host/vector species are fundamental to understand their density and distributions. Human effort to manage the trap data accurately and timely is an exhaustive endeavour when the study area expands and period prolongs.

Status of pyrethroid resistance in Aedes (Stegomyia) aegypti (Linneaus) from dengue hotspots in Klang Valley, Malaysia.

The continued absence of an effective and safe tetravalent dengue vaccine and the lack of specific anti-viral treatment have made mosquito vector control using chemical insecticides as the mainstream for dengue prevention and control. However, the long-term use of chemical insecticides may induce resistance. Hence detection of insecticide resistance in dengue vectors is crucially important in ensuring the insecticide-based intervention in dengue control program is still effective and reliable.

strain AlbB maintains high density and dengue inhibition following introduction into a field population of .

mosquitoes carrying the AlbB strain show a reduced capacity to transmit dengue virus. AlbB has been introduced into wild populations in several field sites in Kuala Lumpur, Malaysia, where it has persisted at high frequency for more than 2 years and significantly reduced dengue incidence. Although these encouraging results indicate that AlbB releases can be an effective dengue control strategy, the long-term success depends on AlbB maintaining high population frequencies and virus transmission inhibition, and both could be compromised by host coevolution in the field.

An elusive endosymbiont: Does occur naturally in ?

are maternally inherited endosymbiotic bacteria found within many insect species. mosquitoes experimentally infected with are being released into the field for borne disease control. These infections induce cytoplasmic incompatibility which is used to suppress populations through incompatible matings or replace populations through the reproductive advantage provided by this mechanism.
