A comparative study on the optimum time and method of collection of Phlebotomus argentipes and other sandflies. (Diptera: Psychodidae).
A uniform method of collection is imperative for generating comparable entomological data in connection with studies on efficacy of vector control measures against sandflies. Two commonly employed methods for sandfly collections i.e. hand collection by aspirator and sticky paper traps were compared under similar ecological conditions to determine the optimum time and method for generating data on relevant indices. Only two P. argentipes male specimens were collected at dusk time from 12 cattle sheds and 40 human dwelling by aspirator method. By sticky traps placed in the same resting shelters, 243 P. argentipes and 58 specimens of 5 other species were collected. However, the collection by sticky traps comprised only males and unfed females. In the morning collection by aspirators 268 sandflies of 8 species in all stages of gonotropic cycle were collected. It is concluded that morning collections by aspirator method can provide objective assessment of control measures. Sticky traps may be useful as additional method for confirming presence of P. argentipes in sprayed areas.
