We propose a treatment strategy combining an initial disinfestation treatment with one of three protective treatments as an alternative for chemical fumigation of almonds and raisins for control of postharvest insect populations. Initial disinfestation treatments using low oxygen controlled atmosphere (0.4% O2) were designed to disinfest product of field populations of pyralid moths; navel oran...

Carob tree ( Ceratonia siliqua L.) is an agro-sylvo-pastoral species that has been classified among the most efficient trees. The first publications on " in-vitro multiplication of are very recent and show conflicting results. Mastery this technique seems necessary to provide increased demand international market for gum extracted from endosperm seed, a polyoside called galactomannan. This work...

Fourteen cations were tested at a 1% concentration (wt:wt), as chlorides, for their effects on the biological activity of the gypsy moth, Lymantria dispar (L.), nuclear polyhedrosis virus (LdMNPV). Cupric chloride was toxic to gypsy moth larvae. Ferrous and ferric chloride were inhibitory to larval growth and development as well as to virus activity. Strontium chloride was inhibitory to virus a...

We developed a computer model for simulating the population dynamics of the almond moth, Cadra cautella (Walker). The model incorporates previously published life history data for the almondmothdeveloping on storedpeanuts, Arachis hypogaeaL., including stage-speciÞc immature developmental time and survival and adult longevity and fecundity. The model was modiÞed so that it also could be used to...

No field failure of azinphosmethyl had been noticed in controlling codling moth from Oregon until 1989. However, in a study conducted by Moffitt et al. during 1986 to 1987, a codling moth population from Medford has been reported resistant to diflubenzuron. It was suspected that selection by other commonly used compounds was probably responsible for this resistance. We initiated our work in 198...

This paper presents the design, fabrication, and testing of a harvester that extracts energy from moth-body vibrations during flight. The target moth is manduca sexta, which has a payload capacity near 1 g, and a dorsal payload volume approximately 8 mm wide and 15 mm tall. Operating within these constraints, the energy harvester is designed to deliver 1 mW of electrical power at 1 VDC for gene...

Communicational disruptionmechanisms for Oriental fruit moth,Grapholita molesta (Busck) (Lepidoptera: Tortricidae), were determined using a suite of mathematical tools and graphical operations that enable differentiation between competitive attraction and non-competitive mechanisms of disruption. Research was conducted in 20 field cages, each covering 12 mature apple trees. Commercial monitorin...

Invasive species can have profound effects on a resident community via indirect interactions among community members. While long periodic cycles in population dynamics can make the experimental observation of the indirect effects difficult, modelling the possible effects on an evolutionary time scale may provide the much needed information on the potential threats of the invasive species on the...
