In this study, efficacy and some characteristics of the local diatomaceous earth (DE) were investigated against been weevils [Acanthoscelides obtectus (Say) (Col.: Bruchidae)] on chickpeas (Cicer arientum L.) under laboratory conditions. In the experiments, Turco000, Turco004, and Turco020 derived from native sources (Ankara, Turkey), and Protector (R), a commercial product, were used. The bioassays were carried out at 25 +/- 1 degrees C temperature, 65 +/- 1% r.h. with six concentrations of DEs (100, 200, 400, 600, 800 and 1000 ppm) at the Plant Protection Central Research Institute, Entomology Laboratory in Ankara in 2016. The mortality of adults was evaluated after the 4th, 7th and 14th days of treatments. In order to determine progeny production (F1), the treated chickpeas were further incubated at the same conditions for the 55-days. Turco000 gave 100% mortality to A. obtectus adults at 1000 ppm after 4th day as Protector (R) at 600 ppm concentration did. The lowest mortality rate was observed at Turco020 at a dose of 100 ppm 7 days after treatment. When the effects of diatomaceous earth formulation on the fertility of Fl were investigated, it was determined that all diatomaceous earth formulation had an effect on different rates. There was no progeny production with Turco000 at 200 ppm concentration at the end of 55-day incubation period and this was followed by Turco004 and Turco020, respectively. Results showed that the protective residual effect of Turco000 continued throughout the experiments. In conclusion, Turco000 can be used as a valuable tool for A. obtectus in stored product pest management programs.
