Effects of contact insecticides pirimifos-methyl and deltamethrin of Indian meal moth Plodia interpunctella Hbn. and Angoumois grain moth Sitotroga cerealella Oliv. in maize, and on bean weevil Acanthoscelides obtectus Say in beans were examined 6 and 18 months after treatment in laboratory environment. Using appropriate methods (EPPO and other), maize and bean were treated with recommended and double rates of the insecticide products: EC formulation of pirimifos-methyl and EC formulation and dust of deltamethrin. After 6 and 18 months, we examined the mortality of P. interpunctella larvae, and 5. cerealella and A. obtectus adults following 2,7 and 14 days of contact with the treated material. In Angoumois grain moth and bean weevil, the resulting progeny was monitored up to FI generation. Both insecticides achieved full mortality of P. interpunctella larvae on the 6-month-old deposit. On the 18-months-old deposit, the same result was achieved with deltamethrin dust (both rates), as well as with pirimifosmethyl and deltamethrin (EC formulation) at the double recommended rates. S. cerealella mortality was 100% for both insecticides and both deposit ages. Regarding A. obtectus, full mortality of adults was found after contact with pirimifos-methyl and deltamethrin dust, while deltamethrin liquid caused low mortality of bean weevil, especially the 18-months-old deposit. FI generation adults of Angoumois grain moth and bean weevil were found only on 18-months-old deposits of the recommended rates of deltamethrin dust and pirimifos-methyl. The tested contact insecticides can provide very long prevention and control of Indian meal moth and Angoumois grain moth in stored maize and bean weevil in stored beens.

The Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), is an insect pest that commonly affects stored and postharvest agricultural products. For the control of insect pests and mites, methyl benzoate (MBe) is lethal as a fumigant and also causes contact toxicity; although it has already been established as a food-safe natural product, the fumigation toxicity of MBe has yet to be demonstrated in P. interpunctella. Herein, we evaluated MBe as a potential fumigant for controlling adults of P. interpunctella in two bioassays. Compared to the monoterpenes examined under laboratory conditions, MBe demonstrated high fumigant activity using a 1-L glass bottle at 1 μL/L air within 4 h of exposure. The median lethal concentration (LC50) of MBe was 0.1 μL/L air; the median lethal time (LT50) of MBe at 0.1, 0.3, 0.5, and 1 μL/L air was 3.8, 3.3, 2.8, and 2.0 h, respectively. Compared with commercially available monoterpene compounds used in pest control, MBe showed the highest fumigant toxicity (toxicity order as follows): MBe > citronellal > linalool > 1,8 cineole > limonene. Moreover, in a larger space assay, MBe caused 100% mortality of P. interpunctella at 0.01 μL/cm3 of air after 24 h of exposure. Therefore, MBe can be recommended for use in food security programs as an ecofriendly alternative fumigant. Specifically, it provides another management tool for curtailing the loss of stored food commodities due to P. interpunctella infestation.
