the mill moth, ephestia kuehniella zeller and indian meal moth, plodia interpunctella (hubner) are two injuriously important pests of stored products worldwide. harobracon hebetor (say) has been used as a biological control agent of moth’s larva in peanut storehouses and as well in packaged cereal products. in the present study, the efficacy of h. hebetor in parasitizing larva of the mill moth ...

Predation of gypsy moth egg masses was studied in Slovakia from 1999 –2002. Predation on naturally laid egg masses was recorded and linear regression was used to test the hypothesis that predation follows a type II vs. type III functional response. We also investigated the role of egg mass predation in gypsy moth population dynamics. The relative contribution of invertebrates vs. vertebrates as...

the tomato leafminer, tuta absoluta (meyrick), is one of the most important pests of tomato, solanum lycopersicum l., in iran. in this research, natural enemies diversity of t. absoluta and proportion of predators or parasitoids density to moth eggs or larvae density on five tomato cultivars including super strain b, super chief, mobil, korral, and early urbana y were studied in an experimental...

Topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine CSR2, CSR4 and CSR2XCSR4 crossbreed races of the silkworm, Bombyx mori L. The results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoo...

Gypsy moth (Lymantria dispar L.) spread is dominated by stratified dispersal, and, although spread rates are variable in space and time, the gypsy moth has invaded Wisconsin at a consistently higher rate than in other regions. Allee effects, which act on low-density populations ahead of the moving population that contribute to gypsy moth spread, have also been observed to be consistently weaker...

The antibacterial effect of a nanostructured film, known as "moth-eye film," was investigated. The moth-eye film has artificially formed nano-pillars, consisting of hydrophilic resin with urethane acrylate and polyethylene glycol (PEG) derivatives, all over its surface that replicates a moth's eye. Experiments were performed to compare the moth-eye film with a flat-surfaced film produced from t...

T recent discovery of light brown apple moth, a leafroller, in California may affect the management of fruit crops, and because it is a quarantine pest in some markets, the discovery has already had implications for domestic and export trade in produce and nursery stock. In New Zealand, light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), was first reported in 1891 ...

The efficacy of mating disruption by using Isomate-M 100 pheromone dispensers and two formulations of microencapsulated sprayable pheromone for management of oriental fruit moth, Grapholita molesta (Busck), was compared with conventional insecticides in large plot studies in Henderson County, North Carolina, in 2000 and 2001. In addition, experiments were conducted in small and large plots to t...

Models of outbreaks in forest-defoliating insects are typically built from a priori considerations and tested only with long time series of abundances. We instead present a model built from experimental data on the gypsy moth and its nuclear polyhedrosis virus, which has been extensively tested with epidemic data. These data have identified key details of the gypsy moth-virus interaction that a...

Goal. To justify the criteria for evaluating effectiveness of adaptive technologies growing entomocultures, which take into account qualitative indicators insects, ecological, economic, and energy-economical system are based on introduction energy-efficient technological elements. Methods. The assessment entomocultures in comparison with regulatory ones was carried out involvement method curren...
