A novel, 10 kb RNA virus—tentatively named ‘Abisko virus’—was discovered in the transcriptome data of a diseased autumnal moth (Epirrita autumnata) larva, as part of a search for the possible causes of the cyclical nature and mortality associated with geometrid moth dynamics and outbreaks in northern Fennoscandia. Abisko virus has a genome organization similar to that of the insect-infecting ne...

For decades, scientists and engineers have been fascinated by cybernetic organisms, or cyborgs, that fuse artificial and natural systems. Cyborgs enable harnessing biological systems that have been honed by evolutionary forces over millennia to achieve astounding feats. Male moths can detect a single pheromone molecule, a sensitivity of roughly 10 grams. Thus, cyborgs can perform tasks at scale...

High levels of resistance to Bacillus thuringiensis Berliner in diamondback moth Plutella xylostella (L.), (LC50 more than 280 ppm) was observed in a watercress greenhouse in Osaka Prefecture in 1988. Populations of egg, larva, pupa and adult of diamondback moth were monitored weekly throughout 1988. Population of the larva fluctuated from nearly 0 to 1,300,000. Three control methods were attem...

Boundary habitats are frequently hot spots for the production and flow of organic matter (OM) and exert strong effects on ecological processes in the habitats which they link. Salt marshes, which are boundary habitats occurring between the land and the sea, are important sources of OM for coastal habitats. Primary productivity and tides are among the main causes of OM production and export from...

Studies were conducted in 1997 and 1998 to evaluate the effects of three particle film formulations consisting of kaolin and adjuvants on neonate larvae, ovipositing adult females, and eggs of the codling moth, Cydia pomonella (L.). Neonate larval walking speed, fruit discovery rate, and fruit penetration rate on apple host plants coated with particle films were significantly lower than on host...

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...

Grain yield is a complex phenomenon, which results from the interaction of various contributing causes highly influenced by environmental variation. Phenotypic selection cannot directly improve characters in heterozygous crops like moth bean unless dissected genetic analysis. A study undertaken to determine extent variability for seed and ten other quantitative 40 genotypes bean. The analysis v...

The uptake of [H]proline by collagen-secreting cells of the locust, Locusta migratoria, and wax-moth, Galleria mellonella, has been investigated by electron autoradiography. The locust cells are around the ejaculatory duct and they secrete collagen in the young adult male, while the wax-moth cells are those which produce the dorsal mass of connective tissue on the abdominal nerve cord during th...

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...
