Insecticide Resistance in Plodia Interpunctella (Hubner) (Lepidoptera: Pyralidae) in New South Wales, Australia

Abstract

Three strains of Indian meal moth, Pludia intevpuncfella, were collected in 1975 from stored foodstuffs and grain storages in New South Wales and their responses to 24 insecticides were compared with a laboratory reference strain. The strains showed 68-, 74.4-and 72.3-fold resistance to endrin, :-53-fold to dieldrin, 12.5-, 14.2-and 11.5-fold resistance to lindane, and > 42-fold resistance to DDT. One strain from Tamworth (strain T) displayed more than 260-fold resistance to malathion and two strains (R and M) showed 25-and 24-fold resistance to malathion. The three strains also had resistance to dichlorvos (2.9 to 3.6-fold), diazinon (7.0 to 9.7-fold), pirimiphos-methyl (4.5 to 4.8-fold) and fenitrothion (7.2 to 8.6-fold). Pre-treatment with triphenyl phosphate overcame most of the malathion resistance of strain T, reducing the resistance factor by more than 97% to 7.4, compared with only 20% and 17% reductions in strains R a n d M to 20. None of the strains was resistant to pyrethrins, synthetic pyrethroids or the carbamate, methomyl.

Efficacy of essential oils to control the Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae)

“…Generally, the control of this insect pest in storage systems depends on synthetic insecticides (organophosphates and pyrethroids) and fumigants (such as methyl bromide or phosphine) (Kim et al, 2014;Mbata and Shapiro-Ilana, 2010). Applications of insecticide had led to resistance in some P. interpunctella populations and the accumulation of chemical residues in food, as well as human exposure to pesticides (Arthur and Phillips, 2003;Attia, 1977;Phillips and Throne, 2010). Moreover, methyl bromide, a high toxic product, has been declared an ozone-depleting substance and therefore is being phased out completely (Rajendran and Sriranjini, 2008).…”

Taxonomic Description, Distribution, and Control Measures of Plodia interpunctella (Hübner, 1813) in Kashmir Valley, India

“…The Food Quality Protection Act (FQPA) has already taken a few carbamate and organophosphate pesticides off the market for post-harvest use. Moreover, certain strains of P. interpunctella have evolved resistance to the organophosphate Malathion and several other organophosphates [32][33][34][35][36][37][38].…”
