How are retrospective accounts of family rearing environments linked to adult personality? We addressed this question by measuring both domains in a sample of 180 reared-apart twins. Twins completed extensive measures of rearing environments (the Minnesota-Briggs History Record, the Block Environmental Questionnaire, the Family Environment Scale, and the Physical Facilities Questionnaire) and a...
The effect of using varied levels of dietary protein with high energy levels in rearing diets on pullet development and on subsequent layer performance in hot climates, was studied using 160 Lohmann White Leghorn pullets. Five replicate groups of 16 pullets, 1 day of age were randomly assigned to each of two series of rearing diets. Pullets in both treatments were fed a 190 g crude protein (CP)...
Larval rearing of Bactrocera invadens Drew, Tsuruta & White (Diptera: Tephritidae) on artiÞcial diet is described. The adaptation process for this insect, when moved from whole mango, Mangifera indica L., fruit rearing to artiÞcial diet based on wheat bran, took between three and Þve generations to reach theplateauof quality control parameters observed for rearing the insect onwhole mango fruit...
An attempt was made to rear the eri silkworm, Philosamia ricini on leaves of caster and reared under laboratory condition. It observed that is a primary potential host silkworm. The growth parameters cocoon characters silkworm were normal. successfully lasted its life cycle ranged from 38 40 days. effective rate rearing, weight pre-spinning larvae, cocoon, shell pupae 70 75 per cent, 6 7 g, 3.0...
Polyester pad was utilized as solid support for rearing Cochliomyia hominivorax Coquerel larvae in liquid diet and compared with the ground meat diet. There were no significant differences in the mean third instar larvae and pupal weights, number of pupae, emergence and rearing efficiency. The tests were conducted through four consecutive generations, presenting no detectable effect in any of t...

Serotonin (5-HT) is known to modulate motor outputs in a variety of animal behaviors. However, the downstream neural pathways of 5-HT remain poorly understood. We studied the role of 5-HT in directional change, or turning, behavior of fruit fly (Drosophila melanogaster) larvae. We analyzed light- and touch-induced turning and found that turning is a combination of three components: bending, ret...
The aim of the present work was to compare the effect of organic production vs standard cage system on welfare and performance of a pure breed (Ancona) vs a commercial strain (Brown Hy-Line) of laying hens through a multifunctional approach (behaviour, tonic immobility, feathers score, antioxidant status of the body, blood parameters, innate immunity and mortality). The trial was carried out in...
