Abstract

Fatty acid composition in head, thorax, and abdomen of male and female specimens of the solitary
wasp species Sphex flavipennis was investigated. Samples were collected from their natural habitats in Tokat
province (Turkey). It is determined that, unsaturated fatty acids are high in females whereas saturated fatty acids
are high in males. Total unsaturated fatty acids of body parts and sexes were found as: 80.19 % in female head,
75.73 % in male head; 81.57 % in female thorax, 81.43 % in male thorax; 79.03 % in female abdomen, 74.68 % in
male abdomen. Total saturated fatty acids of body parts and sexes were found as: 19.57 % in female head but 24.67
% in male head; 14.83 % in female thorax, 16.91 % in male thorax; 19.77 % in female abdomen, 22.78 % in male
abdomen. The highest amounts of fatty acids are oleic acid and linoleic acid ranging between 27.68 % - 52.65 %
and 19.00 % - 37.36 %, respectively. Differences between body parts as well as male and female insects are due to
diverse physiological and metabolic functions

Soliter Yaban Arısı, Sphex flavipennis (Insecta: Hymenoptera)’in Eşey ve Vücut Kısımlarında Yağ Asit Kompozisyonu

Abstract

Soliter yaban arısı Sphex flavipennis türüne ait erkek ve dişi örneklerin baş, toraks ve abdomen kısımlarında
yağ asidi kompozisyonu araştırıldı. Örnekler Tokat ilinde doğal habitatlarından toplandı. Çalışmamızda doymamış
yağ asitleri dişilerde, doymuş yağ asitleri ise erkeklerde yüksek bulunmuştur. Eşeyler ve vücut kısımlarına göre
toplam doymamış yağ asitleri şu şekilde bulunmuştur: dişinin başında % 80.19, erkeğin başında % 75.73; dişinin
toraksında % 81.57, erkeğin toraksında % 81.43; dişinin abdomeninde %79.03, erkeğin abdomeninde % 74.68.
Toplam doymuş yağ asitleri şu şekilde bulunmuştur: dişinin başında % 19.57, erkeğin başında % 24.67; dişinin
toraksında % 14.83, erkeğin toraksında % 16.91 in; dişinin abdomeninde % 19.77, erkeğin abdomeninde % 22.78.
Yağ asitleri arasında en yüksekleri oleik asit ve linoleik asittir, miktarları sırasıyla 27.68% - 52.65% ve 19.00% -
37.36% arasında değişmektedir. Vücut kısımları ile erkek-dişi arasındaki farklılıklar çeşitli fzyolojik ve metabolik
fonksiyonlardan kaynaklanmaktadır.
