[Simplification of the collecting method of adult sweetpotato weevils from artificial diets]
Japanese Journal of Applied Entomology and Zoology 55 (1), 22-24
Abstract: The West Indian sweetpotato weevil Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) is a major pest of the sweet potato Ipomoea batatas (L.) Lam (Solanales: Convolvulaceae) in some countries. In order to improve the mass-rearing systems involved in an eradication program employing the sterile insect technique (SIT), we improved the efficiency of the method used for collecting adult weevils from artificial larval diets; this was done by using the combination of a sieve and Tullgren apparatus. Using this combination, we could collect 95.4% of weevils from artificial diets. Furthermore, the time spent in collection with this method was approximately one-fifth of that spent with the existing hand-sorting method. These results showed that this new collection method will improve the efficiency of mass rearing of West Indian sweetpotato weevils.
