  1. Entomological evaluations: base line (LB), 2 months (E1) and 12 months (E2) after the application od the microencapsulated formulation. D1 figures represents overall insect density average per. infested house (standard deviation; number of infested houses); D2 figures represents density. average per evaluated house (standard deviation; number of evaluated houses). Standard deviation is calculated for n>2.
