Özet:

 The seven-spotted ladybug, Coccinella septempunctata Coleoptera: Coccinellidae L., is a polyphagous predatory species that feeds on many species of aphids and some soft-bodied insects in both larval and adult stages. For this reason, C. septempunctata L. Coccinellidae is very important in biological control. In this study, the egg structure and first larval period of C. septempunctata were examined using stereomicroscopy and scanning electron microscopy. C. septempunctata eggs are clear and oval, appearing elliptical dorsally and ventrally and slightly rounded at both ends. The first larvae that emerge from C. septempunctata eggs are dark brown and have 3 pairs of legs. The abdomen consists of 8 segments. In SEM photographs, star-shaped structures were observed on both sides of the strip on the dorsal surface of the thorax and abdomen of the larvae. Large stigma openings were found at equal intervals on the lateral of abdomen. The egg and larval structure of the invasive species C. septempunctata is described in detail.

 Yedi noktalı uğur böceği, Coccinella septempunctata Coleoptera takımı: Coccinellidae L., hem larval hem de ergin dönemlerinde çok sayıda yaprak biti türü ve bazı yumuşak gövdeli böceklerle beslenen polifag bir predatör türdür. Bu nedenle C. septempunctata L. Coccinellidae biyolojik mücadelede oldukça önemlidir. Bu çalışmada, C. septempunctatanın yumurta yapısı ve birinci larval dönemi stereomikroskop ve taramalı elektron mikroskobu kullanılarak incelenmiştir. C. septempunctata yumurtaları şeffaf ve ovaldir, dorsal ve ventral olarak eliptik ve her iki uçta hafif yuvarlaktır. C. septempunctata yumurtalarından çıkan ilk larvalar koyu kahverengi renktedir ve 3 çift bacağa sahiptir. Abdomen 8 segmentten oluşmaktadır. SEM fotoğraflarında larvaların toraks ve abdomeninin dorsal yüzeyinde şeridin her iki yanında yıldız şeklinde yapılar gözlenmiştir. Abdomenin lateralinde eşit aralıklarla büyük stigma açıklıkları bulunmuştur. İstilacı tür C. septempunctatanın yumurta ve larval yapısı detaylı olarak tanımlanmıştır.
