inhibitory effects of lavandula angustifolia and zataria multiflora essential oils were evaluated on reproduction and f1 progeny production of callosobruchus maculatus. insect’s culture and bioassays were conducted at 29 ±1ºc, 60±5% rh and dark condition. essential oils were taken by hydrodistilation. the results indicated that there was a negative and significant linear relationship between re...

apple is the most important fruits in the world and development of vegetative rootstocks is the priority of our country. to obtain apple rootstocks compatible with soil conditions in iran, many crosses were carried out among native-dwarf genotype (azayesh and morabaee) as female parents and commercial rootstocks (b9, m9, m27) as male parents from 2005 to 2007. primary evaluation of progenies wa...

Vertical transmission of yellow fever virus from orally infected females to their progeny was experimentally demonstrated in 2 Aedes aegypti colonies from the Dakar and Koungheul regions in Senegal. A total of 10,530 F1 adult mosquito progeny were tested. The overall vertical transmission rate was 0.97%, with no significant difference between the Dakar and Koungheul colonies. The infection rate...

Fetal programming suggests that maternal stimulation and nutrition during the period of fetal development can program progeny. Conjugated linoleic acid (CLA), an isomer acid, has been characterized in several aspects, but few studies have performed on its involvement reproduction programming. The aim this study was to evaluate F1, F2 F3 progeny female mice supplemented with CLA pregestational g...

Pressure-volume curves were determined for black spruce (Picea mariana (Mill.) BSP) trees from four full-sib families. During the first two years, trees were measured from a plantation on a dry site. In the third year, trees were sampled from the dry site and a wet site. Diurnal measurements of shoot water potential allowed in situ shoot turgor to be estimated in addition to standard water rela...
