Abstract

Spermatheca and egg morphology of Eurygaster austriaca (Schrank, 1778) were studied by optical and scanning electron microscopy (SEM). The spermatheca of E. austriaca is characterized by a spermathecal bulb, a pumping region, distal and proximal fl anges and ducts, and a genital chamber. Each female was shown to deposit 14 green eggs on average in mass. The spherical eggs averaged 1.05 ± 0.05 mm in diameter. The first external evidence of embryonic development was the appearance of 2 red eye spots opposite each other beneath operculum followed by the appearance of a blackish T-shaped egg-burster between the eye spots. The thickened highly sclerotized egg-burster has sucker-shaped structures on the both sides of the tail. Egg surfaces are covered with clearly marked polygon patterns with tubercles. There were 17-19 aero-micropylar processes shaped like truncated cones scattered among the polygons.

Özet

Eurygaster austriaca (Schrank, 1778) yumurta ve spermateka morfolojisi ışık ve taramalı elektron mikroskobuyla incelendi. E. austriaca’nın spermatekası spermateka haznesi, pompalama bölgesi, distal ve proksimal yaka ve kanallar ve genital oda ile karakterize edilir. Her bir dişi bir yumurta kümesinde genellikle yeşil renkli 14 yumurta bırakır. Yuvarlak şekilli yumurtalar ortalama 1,05 ± 0,05 mm çapındadır. Embriyonik gelişimin ilk belirtisi operkulumun altında karşılıklı yer alan iki kırmızı leke ve bunu takiben bu lekelerin arasında görünen T şeklindeki siyahımsı yumurta kırıcısının görünüşüdür. Kalın ve oldukça sklerotize olan yumurta kırıcısı kuyruk kısmının her iki tarafında vantuz şeklinde yapılara sahiptir. Yumurta yüzeyi kolaylıkla fark edilen tüberküllü poligonal yapıyla kaplıdır. Koryonik poligonların arasında kesik koni şeklinde 17-19 aero-mikropil bulunur.
