Abstract

Callosobruchus chinenis and C. maculatus are among the most common and important species causing significant damage to stored pulses. This research were carried out to evaluate the efficacy of sulfuryl flüoride gas on the different ages of egg stage of Callosbruchus chinensis at Ankara University, Faculty of Agriculture, Department of Plant Protection, Stored Product Pests laboratory during 2020-2021. The efficacy of sulfuryl fluoride gas were determined on the 0-24, 24-48, 48-72 and 72-96 h egg stage for 24 h exposure at 25 oC and 75% relative humidity condition. Dose rates of sulfuryl flüoride in this research were 0, 10, 15, 20, 30, 40, 50, 60 and 120 g m-3. Fumigation using sulfuryl fluoride were carried out in gas-tight, with volume of 28.3 l Labconco® fumigation chambers. Eggs laid on the half chickpea seads glued onto the glass slide were counted and recorded according to the changing yhe colour to the milky white (alive) after 14-d from fumigation.  Results showe that LD50 values changed depending on the age of egg satge, and the most tolerant age of egg stage considering LD50 values was calculated as 48-72 h old egg stage. Additionally, dose rate for 100% mortality for all ages of egg stage in the experiment were determined as 50 g m-3.  Researh results showed that sulfuryl fluoride could be effective fumigant as an alternative to phosphine gas.
