Background & objectives: In sterile insect technology (SIT), mating competitiveness is a pre-condition for the reduction of target pest populations and a crucial parameter for judging efficacy. Still, current SIT trials are being hindered by decreased effectiveness due to reduced sexual performance of released males. Here, we explored the possible...

Food location by mosquitoes is mediated by resource-derived olfactory and visual signals. Smell sensation is intermittent and dependent on the environment, whereas visual signals are continual and precede olfactory cues. Success of mosquito bait technology, where olfactory cues are used for attraction, is being impeded by reduced attractiveness. De...

Nectar is the staple diet of adult mosquitoes in the wild, but its availability is inconsistent and can be affected by rainfall. In urban centers, Aedes vectors commonly use man-made containers as their major habitat; however, they can colonize any items replenished by rainfall. Garbage output has increased significantly in recent years, at a time...

Yearly, huge amounts of sock refuse are discarded into the environment. Socks contain many molecules, and worn ones, which are rich in smell-causing bacteria, have a strong influence on animals’ behaviors But, the impacts of sock odor on the oviposition behavior of dengue vectors is unknown. We assessed whether Aedes albopictus changes its oviposit...

In dengue vector control, attempts to minimize or replace the use of pesticides have mostly involved use of predators, but success has been severely impeded by difficulties associated with financial and environmental costs, predator mass production, and persistence in target habitats. Visual deterrents have been used successfully to control animal...

In dengue mosquitoes, successful embryonic development and long lifespan are key determinants for the persistence of both virus and vector. Therefore, targeting the egg stage and vector lifespan would be expected to have greater impacts than larvicides or adulticides, both strategies that have lost effectiveness due to the development of resistance...

In nature, adult mosquitoes typically utilize nectar as their main energy source, but they can switch to other as yet unidentified sugary fluids. Contemporary lifestyles, with their associated unwillingness to consume leftovers and improper disposal of waste, have resulted in the disposal of huge amounts of waste into the environment. Such refuse o...

Body size is a physical factor of crucial importance underlying important traits of the reproductive dynamics of both sexes in mosquitoes. Most studies on the influence of body size in mating success of dengue vectors addressed sperm transfer to females and did not consider egg production, a prerequisite for population maintenance; male body size i...

Dengue mosquitoes are evolving into a broader global public health menace, with relentless outbreaks and the rise in number of Zika virus disease cases as reminders of the continued hazard associated with Aedes vectors. The use of chemical insecticides-the principal strategy against mosquito vectors-has been greatly impeded due to the development o...

The HCVF Toolkit for Malaysia was primarily developed to help forest managers comply with Principle 9 in both the Forest Stewardship Council and the Malaysian Criteria and Indicators for Forest Management Certification. These are standard adopted by the National Steering Committee for certification of natural forests in Malaysia. Here, we use it to...

Mount Singai in Bau District was settled by BiSingai tribe for almost 300 years before they moved downhill to 14 villages some 40 years ago. They extracted forest products and planted crops in their clearings at the mountain. The documentation of these plants and impacts of these activities on their composition in the area would be an interesting d...

Knowledge of a range of pedagogical skills is also elemental to ensure effective delivery of instruction, enabling meaningful transfer of knowledge takes place. Recognizing the need to develop and upgrade its academics’ pedag...

This paper discusses a study of the information sources employed by students to get information regarding University Malaysia Sarawak (UNIMAS) and also the factors influencing students’ choice of UNIMAS. In addition, differences in sources of information and factors of influence based on types of faculty and selected student demographics were also...

Shifting cultivation is practiced by millions of farmers in the tropics and has been accused of causing deforestation and keeping farmers in poverty. The assumed positive relationship between fallow length and crop yields has long shaped such negative opinions on the sustainability and environmental impact of the system, as population growth is bel...

SUMMARY A large area of peatland in Sarawak occurs in Mukah Division. Although, considered unsuitable for the cultivation of certain crops, peatlands have been used by the local communities for subsistence agriculture and sago cultivation for generations. When the Land Custody Development Authority (LCDA) allocated 30,000 hectares of land for sago...
