Abstract: Comparative genomic hybridization (CGH) with a probe mixture of differently labeled genomic DNA from females and males highlighted the W chromosomes in mitotic plates and the W chromatin in polyploid interphase nuclei of the silkworm Bombyx mori, the flour moth Ephestia kuehniella, and the wax moth Galleria mellonella. The overproportionate fluorescence signal indicated an accumulatio...
Comparative genomic hybridization (CGH) with a probe mixture of differently labeled genomic DNA from females and males highlighted the W chromosomes in mitotic plates and the W chromatin in polyploid interphase nuclei of the silkworm Bombyx mori, the flour moth Ephestia kuehniella, and the wax moth Galleria mellonella. The overproportionate fluorescence signal indicated an accumulation of repet...
Spindles from the gonads of five insect species were examined after conventional preparation for electron microscopy. The aim of the study was to determine (1) the range of variation of the spindle membranes between mitotic and meiotic cells and (2) the correlation of possible differences with the microtubule content of the spindles. The study involved four moth species, Ephestia kuehniella, Ph...
a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...
Use of insecticides can have disruptive effects on the environment. Replacing the chemical compounds in these insecticides with plant materials, however, can be a safe method with low environmental risk. In the current study, chemical composition and insecticidal activities of the essential oil from cardamom, Elettaria cardamomum L. (Maton) (Zingiberales: Zingiberaceae) on the adults of three s...
Mediterranean flour moth, Ephestia kuehniella, is a cosmopolitan pest of stored products, and its eggs are widely used to rear parasitoids and predators for biological control programmes. This experiment investigated how larval population density affected the survival rate and reproductive output of this species under four rearing densities ( larva per 2 g food per vial; or 00, 500 or 000 larva...
The objective of this work was to study the insecticidal effect of labramin, a protein that shows lectin-like properties. Labramin was isolated from seeds of the Beach Apricot tree, Labramia bojeri A. DC ex Dubard (Ericales: Sapotaceae), and assessed against the development of the Mediterranean flour moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), an important pest of stored products ...
The fiber properties of lepidopteran silk depend on the amino acid repeats that interact during H-fibroin polymerization. The aim of our research was to relate repeat composition to insect biology and fiber strength. Representative regions of the H-fibroin genes were sequenced and analyzed in three pyralid species: wax moth (Galleria mellonella), European flour moth (Ephestia kuehniella), and I...
در این پژوهش، ویژگی های بیوشیمیایی پروتئازها، تاثیر تغذیه از طعمه های مختلف، گرسنگی و بازدارنده های پروتئازی داخلی در معده ی سن شکارگرandrallus spinidens f. (hemiptera: pentatomidae) مورد بررسی قرار گرفت. اسیدیته ی بهینه ی فعالیت پروتئازی کل در معده ی میانی این سن 8 بود که البته اوج کوچکی نیز در اسیدیته ی 6 مشاهده شد. با استفاده از سوبستراها و بازدارنده های اختصاصی وجود سرین پروتئینازها، سیستئی...
Alternative food sources for the ladybird Brumoides foudrasii (Mulsant) (Coleoptera: Coccinellidae).
The predator Brumoides foudrasii (Mulsant) (Coleoptera, Coccinellidae) has been naturally found in plants infested by mealybugs. In this study, the striped mealybug Ferrisia dasylirii (Cockerell) (Hemiptera, Pseudococcidae) and Anagasta kuehniella Zeller (Lepidoptera, Pyralidae) eggs were evaluated as diets for the development and reproduction of B. foudrasii. Brumoides foudrasii immatures deve...
