New Records Of Agromyzidae (Diptera) From Western Turkey, Hasan Sungur Civelek

Insecta Mundi

Specimens were collected once a week from Mugla province, western Turkey, in 2000 and 2001 from cultured and non-cultured plants. During this study Ophiomyia pulicaria ( Meigen, 1830); Aulagrornyza buhri (de Meijere, 1938); Chromatomyia scolopendri (Robineau-Desvoidy, 1851); Liriornyza flaveola (Fallen 1823); Liriomyza sativae Blanchard, 1938; Phytomyza angelicae Kaltenbach, 1872; Phytomyza conyzae Hering, 1920; Phytomyza rufipes Meigen, 1830; Phytomyza thysselinivora Hering, 1924 are newly recorded for the Turkish leafminer fauna. Morphological descriptions, hosts and their general distributions are given.

Use Of Nonsettable Eggs To Evaluate Turkey Hen Fertility, M. R. Bakst, S. Mcgary, I. Estevez, T. Knapp

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The use of nonsettable eggs (checked, cracked) to perform fresh egg breakouts to estimate true fertility and to assess the rate of sperm penetration of the perivitelline layer overlying the germinal disc was evaluated. Germinal discs and the perivitelline layer overlying the germinal disc were accessible for assessments. The stage of blastodermal development positively correlated (r = 0.65, P < 0.0001) with eggshell thickness. It was also determined that the perivitelline layer of nonsettable eggs could be isolated and stained to determine the presence or absence of sperm holes. True fertility of nonsettable eggs (checked and cracked only) and settable eggs was 90 and 95%, respectively. It was concluded that checked and cracked eggs could be used to estimate the true fertility of a flock.
