A series of studies was conducted to determine the effects of temperature on toxicity of the insect growth regulator methoprene to eggs and larvae of Plodia interpunctella (Hübner), the Indianmeal moth. When methoprene was applied to Kraft paper at the rate of 0.0003 mg of active ingredient [(AI)]/cm2, there was little direct toxicity against eggs of P. interpunctella, and temperature did not a...

The effects of shelving type, packaging, and release height on success of Trichogramma deion Pinto & Oatman (Hymenoptera: Trichogrammatidae) parasitizing Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) eggs was studied under laboratory conditions. In trials on multipletiered gondola-type or open shelving units, with or without packaging, foraging success was evaluated by comparing paras...

SANNA PASSINO G., E. BAZZONI, M. D. L. MORETTI. 2004. Aceites esenciales microcapsulados activos contra polilla indianmeal. Bol. San. Veg. Plagas, 30: 125-132. Los efectos tóxicos de los aceites esenciales microcapsulados de Rosmarinus officinalis y de Thymus vulgaris fueron estudiados contra larvas de Plodia interpunctella. La actividad de aceite fue observada después de la contaminación de la...

Two field strains of the Indianmeal moth, Plodia interpunctella (Hübner); red flour beetle, Tribolium castaneum (Herbst); and lesser grain borer, Rhyzopertha dominica (F.), and one field strain of the rusty grain beetle, Cryptolestes ferrugineus (Stephens), were collected from hard red winter wheat stored on farms in northeastern Kansas. Fifty eggs of P. interpunctella and 25 beetle adults of e...

Phosphine resistance in stored-product insects occurs worldwide and is a major challenge to continued effective use of this fumigant. We determined resistance frequencies and levels of resistance in Tribolium castaneum and Plodia interpunctella collected from California almond storage and processing facilities. Discriminating doses of phosphine were established for eggs and larvae of P. interpu...

Dried apricot is one of the stored fruit most endangered to be infested by the Indianmeal moth, Plodia interpunctella (Hübner). The aim of the present study was to identify volatile compounds from dried apricot that elicit an electrophysiological response in P. interpunctella adults. The volatiles were collected from the headspace of a glass vial with dried apricots using closed-loop-stripping ...

This study investigated the acaricidal and insecticidal effect of local lupin (Lupinus albus L. Fabaceae) seed extract against Tetranychus urticae Koch (Acari: Tetranychidae), Callosobruchus maculatus F. (Coleoptera: Chrysomelidae), Plodia interpunctella (Hubner) (Lepidoptera: Pyralidae) metabolite content seeds. In tests for T. leaf-disk bioassay was employed. Contrarily, two μL were topically...

This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...

The Indianmeal moth, Plodia interpunctella (Hübner), was selected as a representative stored-product moth to test the validity of contour mapping of trap catch for pest monitoring in warehouses and retail stores. Three experiments, each replicated five times, were conducted in a 3.2 by 9.0-m aluminum shed. Each experiment involved placing pupae at a single release point (source) and recording t...
