The aim of the study was to evaluate egg shell quality characteristics, mineral content in the egg shell, and serum mineral concentration during the egg formation process as influenced by oviposition ...
An experiment with laying hens and broiler breeders of two ages (young 22 vs. 36 weeks, old 83 vs. 64 weeks) and at temperatures of 20 and 28°C was carried out to evaluate the interactions between ...
In an experiment with three strains of Dominant genotype the effect of oviposition on egg quality characteristics was investigated. Laying hens of the Blue strain (group 1), Plymouth Rock (group 2) an...
This study was conducted to examine calcitonin (CT) receptor binding in the membrane fraction of the endometrium of the shell gland of laying hens by the use of [125I] CT binding assays. Specific [125...
In this study a selection experiment was carried out in order to investigate the effectiveness of index selection including oviposition time as a selection trait for persistency of laying strain build...
The oviposition preference of the cabbage moth, Mamestra brassicae L. (Lepidoptera: Noctuidae) was investigated on white cabbage cultivars under field conditions in two vegetation periods. Signifi...
Cabbage White Butterfly, Pieris brassicae L. is widely distributed pest world wide and causes severe damage to white cabbage (Brassica oleracea var. capitata f. alba L.). We studied oviposition pr...
The aim of the present study was to determine the oviposition preference of Small White (Pieris rapae L.) on five different white cabbage (Brassica oleracea var. capitata f. alba) cultivars. The exp...
Adult emergence, oviposition and larval behaviors of the teak beehole borer (Xyleutes ceramica), a major pest moth of teak, were studied in the laboratory and the plantations in northern Thailand. Adu...
Compsilura concinnata is a gregarious tachinid which lays eggs directly into a host larva with a sickleshaped ovipositor. The oviposition and immature development of C. concinnata was examined using t...
We clarified the relationship between environmental factors and the growth of seven Eucalyptus species and Casuarina obesa planted at an afforestation site in southern Western Australia’s wheatbelt. T...
The pulse beetle Callosobruchus chinensis Linn. (Coleoptera: Bruchidae) is one of the major pests infesting stored pulses and is distributed worldwide. Plants and plant products possessing insectici...
Laboratory experiments were conducted to assess oviposition deterrence of Acorus. calamus L. extracts to the melon fly, Bactrocera. Cucurbitae COQ. Laboratory reared flies of uniform age were provid...
Two experiments were carried out to investigate the effect of the time of oviposition on egg quality characteristics in two different housing systems (cages vs. litter). ISA brown hens from 20 to 64 w...
Physiological mechanisms, involved in unusual ovulatory sequences in domestic hen are remaining undefined. One hundred individually caged white leghorn birds were divided into two equal groups viz. co...
