Mosquito Resistance Towards Chemical Based Insecticides

Tuesday, 02 Aug 2016 / Admins / In Technology

Dengue. There are more than 120,000 cases of the disease in Malaysia last year.

Of course this disease is a huge health issue, and a burden on Malaysia. This disease is not a new one.

The prevention of this disease is not exactly difficult, but how is it that we are still failing to contain this disease from continuing to plague Malaysians?

World Health Organization (WHO) Director-General Margaret Chan has said in May 2016 that mosquito control “failures” as root causes of the ongoing Zika crisis in an address to the World Health Assembly.

Chan said that countries “dropped the ball” on mosquito control in the 1970s and called the ending of effective control practices a “massive policy failure.” She said that abandoning policies that kept mosquito numbers down set the stage for a resurgence of a disease that had “slumbered” for six decades in Africa and Asia, only to “wake up on a new continent to cause a global health emergency.”

In a nutshell, as it is evident at the world stage, this failure can also be attributed to the rise of dengue cases in Malaysia. Despite the millions of ringgit being spent on mosquito control, we are still using decades old technology without any attempts to innovate the way these disease carrying mosquitoes are dealt with.

“The definition of insanity is doing the same thing over and over again, but expecting different results.” This quote certainly rings true here.

It is widely known that mosquitoes has the capability to develop resistance towards chemical based pesticides used in fogging activities. Now there are reports emerging from Brazil that mosquito larvae are showing signs of resistance towards temephos.

Mateus Chediak et al of the Universidade Federal de Viçosa, Departamento de Entomologia, Viçosa, MG, Brasil, in a report entitled “Spatial and temporal country-wide survey of temephos resistance in Brazilian populations of Aedes aegypti” concluded that, “temephos resistance in Brazilian populations of the Aedes aegypti mosquito spread during the 12-year survey period, showing that resistance is now widespread and there is little hope of achieving effective mosquito control with this insecticide. Alternative insecticides aided by the preventive elimination of potential mosquito breeding sites are necessary.”

We need new ideas. We need new innovations.

This is where EntoGenex has succeeded in creating an effective biolarvicide to control the population of mosquito larvae. Unlike the chemical based temephos, MOUSTICIDE is made using a mosquito peptide, and as such, mosquito larvae will not be able to develop resistance towards it.

We expect this innovative product will overcome this resistance crisis. Support and innovative community engagement in applying these innovations are crucial.
