P. J. Wege , A. F. Bywater , G. N. J. Le Patourel and M. A. Hoppé | Full Paper | 2002

The processes by which insects acquire toxic doses of the microencapsulated formulation of lambda-cyhalothrin (Demand CS) were studied using the German cockroach, Blattella germanica (L.). Cockroaches exposed to treated substrates acquired toxic doses of the insecticide rapidly, and HPLC analysis of...

MICROCAPSULE STRUCTURE: ITS EFFECT ON THE EFFICACY AND BEHAVIOUR OF AN INSECTICIDE

M. A. Hoppé , P. J. Wege , A. F. Bywater and S. D. Weeks | Poster | 1999

Insecticide treatment of surfaces is a well proven technique for the control of insect pests in the urban environment. The aim of these applications is to leave a residual deposit of insecticide which remains lethal to the target insect for an extended period. However, the efficacy of these treatmen...
