An Innovative Approach to Mosquito Control

Sumitomo Chemical (U.K.) plc  (SCUK) has been participating in annual public health mosquito control programs run by the Greek Ministry of Health. With its numerous islands and excellent beaches and swimming Greece is a popular vacation destination. But with an ideal climate for insects it is also home to many mosquitoes.

In the north of Greece is the city Thessaloniki, home to around 1 million people. To the east of Thessaloniki are busy tourist areas, while to the west is a huge area of rice production, comprising approximately 60,000 ha. The rice fields provide a fertile breeding ground for mosquitoes and every summer the mosquito populations reach levels that cause serious problems for residents and tourists alike.

Control of these rice field mosquitos was traditionally accomplished by the use of mosquito larvicides, formerly organophosphate compounds but nowadays almost entirely bacterial larvicides. These are very effective but, due to the large area that needs to be covered, must be dispersed by aerial spraying. This is an effective method until the end of July when the rice crop has grown to such an extent that the foliage prevents the larvicide from reaching the water, at which point mosquito control treatments cannot be carried out.

Sumitomo Chemical (UK) Plc became involved in a new project to apply adulticide products at the end of the larvicide treatment period. The application is made by helicopters fitted with environmental measuring devices and a GPS system. By integrating GPS and environmental information (e.g. the wind speed and direction) with the spraying controls, it is possible to accurately deliver a very small quantity of treatment to the target area. The use of Ultra Low Volume (ULV) spray equipment, which breaks the sprayed liquid into billions of minute droplets, means that a greatly reduced quantity of insecticide is needed compared to conventional spray methods.

The product chosen for this project is Pesguard® S102, part of the Pesguard® Professional range of pest control products marketed by Sumitomo Chemical (UK) Plc. Because of its very high efficacy against mosquitoes, and also because of its favourable environmental and safety profile, this product is ideally suited for the task. The formulation is water-based and contains Sumithrin®, a synthetic pyrethroid insecticide developed by Sumitomo Chemical (UK) Plc’s parent Sumitomo Chemical Company, Ltd. of Japan. Sumithrin is an active ingredient with a particularly low mammalian toxicity. Its safety profile is so strong that it is widely used as an active ingredient in human anti-parasitic pharmaceutical products, especially as a treatment against head lice. In conjunction with this it is a chemical that is rapidly and naturally broken down by sunlight which, like mosquitoes, is in plentiful supply in Greece.

Sumitomo Chemical (UK) Plc has been supplying Pesguard® S102 for this use for several years. The product gives excellent efficacy with an extremely low dosage of active ingredient per hectare.
