Recent decades were characterized by genetic selection of broiler and layer chickens for enhanced growth rate and meat yield or intensified egg production, respectively. It is to be expected that genetic selection for various traits would also influence embryo development. The effects of different strains of chickens on egg weight, stage of blastoderm, variation of the blastoderm development and Pearson correlation between egg weight and stage of blastoderm at oviposition were studied in the current study. Hatching eggs were randomly collected from three layer chicken lines (Layer-1, Layer-2, and Layer-3) raised in Poultry Research Institute, and two broiler grandparent flocks (Female and Male) from Aviagen Anadolu. The age of all chicken lines was 36 week. A total of 30 eggs in each line were used, and egg weight and the blastoderm development of the embryos were determined at oviposition time. At the end of the research, significant difference in egg weights (P0.05). The mean stage of blastoderm development in male grandparent line eggs significantly lower than other four genetic lines (P

American serpentine leafminer, Liriomyza trifolii, is a polyphagous insect pest that feeds on a wide range of vegetable and ornamental plants around the world. To develop an effective IPM program, information on the seasonal field distribution and population dynamics of leafminer and its parasitoids is very important. Therefore, seasonal abundances and spatial distributions of, L. trifolii on snap bean and squash were studied during four crop growing periods between 2013 to 2015 in Homestead, Florida. The mean numbers of mines, larvae, pupae, emerged adults, and parasitoids on snap bean were highest at 2 weeks after planting during all four growing periods. Whereas, the mean numbers of mines, larvae, pupae, emerged adults, and parasitoids on squash were highest at 3 weeks after planting during all four growing periods. L. trifolii distributions tended to be aggregated on snap bean at 2 weeks after planting during most of growing periods but had uniform distributions on squash at 2 weeks after planting during most of growing periods. Similar results were seen on the distribution of leafminer parasitoids on both bean and squash.

Bu çalışma ile Aydın ili Umurlu, Dalama ve Çakmar mahallelerinden seçilen üç zeytin bahçesinde Zeytin sineği (Bactrocera oleae (Gmelin)) (Diptera: Tephritidae)’ nin mevsim içinde ortaya çıkış zamanı, populasyon değişimi ve meyvelerdeki bulaşıklılık oranı belirlenmeye çalışılmıştır. Çalışmada her bir bahçeye birer adet %2 diamonyum fosfat içeren McPhail (McPhail) ve feromon kapsüllü görsel sarı yapışkan tuzak (feromon), ayrıca üçer adet içerisine amonyum asetat konulmuş epondorf tüplerin monte edildiği görsel sarı yapışkan tuzaklar (AA) asılmıştır. Çalışma 2009-2011 yılları arasında yürütülmüş ve tuzaklar haftalık olarak kontrol edilmiştir. Yapılan populasyon takibi çalışmaları sonucunda tuzaklarda ilk ergin sinekler genel olarak Ekim ayının ortalarında yakalanmış ve mevsim süresince devam etmiş ve Aralık ayının ortalarına doğru popülasyonun sıfır düzeyine indiği gözlemlenmiştir. Örnekleme alanlarında Zeytin sineği populasyonu çok düşük düzeylerde seyretmiştir. Ancak popülasyonun maksimuma ulaştığı 2009 yılında Umurlu’ daki bahçede daha yüksek bir popülasyon ortaya çıkmış ve 30 Ekim 2009 tarihinde feromon tuzakta 307,0 birey/tuzak birey saptanmıştır. Popülasyon düzeyleri aynı tarihte aynı bahçede McPhail tuzakta 70,0 birey/tuzak, AA tuzaklarda ise ortalama 51,3 birey/tuzak olarak belirlenmiştir. Meyvelerde en fazla bulaşıklılık oranı ise yine aynı yıl %17,2 olarak Umurlu’da bulunmuştur. Aynı tarihte Dalama ve Çakmar’daki bahçelerde de sırasıyla feromon tuzaklarda 45,0 birey/tuzak ve 3,0 birey/tuzak; McPhail tuzaklarda 8,0 birey/tuzak ve 1,0 birey/tuzak; AA tuzaklarda ise ortalama 4,7 birey/tuzak ve 0,3 birey/tuzak olarak belirlenmiştir. Dalama ve Çakmar’da en fazla vuruk oranları sırasıyla %8,9 ve %3,7 olmuştur. Çalışmadaki diğer yıllarda hem popülasyon hem de meyvelerdeki vuruk oranları çok düşük gerçekleşmiştir.
