Testosterone, Progesterone, And Fsh Levels In Pimpla Turionellae L. (Hymenoptera: Ichneumonidae) And Its Host Galleria Mellonella L. (Lepidoptera: Pyralidae), Fevzi̇ Uçkan, Deni̇z Çevi̇rgen, Ayli̇n Er Jan 2012

Testosterone, Progesterone, And Fsh Levels In Pimpla Turionellae L. (Hymenoptera: Ichneumonidae) And Its Host Galleria Mellonella L. (Lepidoptera: Pyralidae), Fevzi̇ Uçkan, Deni̇z Çevi̇rgen, Ayli̇n Er

Turkish Journal of Zoology

Various vertebrate-type steroid and gonadotropin hormones have been identified in invertebrates, including insects; however, studies in this area are not sufficient to presume a generalized role for these hormones. We identified testosterone, progesterone, and follicle-stimulating hormone (FSH) in the whole-body homogenates of Galleria mellonella L. (Lepidoptera: Pyralidae) and its parasitoid Pimpla turionellae L. (Hymenoptera: Ichneumonidae). Testosterone concentration significantly decreased from early instars to last instars and pupal stages of G. mellonella; however, no significant difference was observed in progesterone levels at different stages. FSH concentration reached the highest level at the pupal stage of G. mellonella. No significant difference was …


Karyological Characteristics, Morphological Peculiarities, And A New Distribution Locality For Talpa Davidiana (Mammalia: Soricomorpha) In Turkey, Mustafa Sözen, Ferhat Matur, Faruk Çolak, Sercan Irmak Jan 2012

Karyological Characteristics, Morphological Peculiarities, And A New Distribution Locality For Talpa Davidiana (Mammalia: Soricomorpha) In Turkey, Mustafa Sözen, Ferhat Matur, Faruk Çolak, Sercan Irmak

Turkish Journal of Zoology

Talpa davidiana is the least known species of the genus Talpa, and the karyotype of this species is still unknown. Its distribution records are also very scattered. The karyological, cranial, and pelvic characteristics of 2 samples from Kızıldağ in Adana Province were analyzed for the first time. It was determined that T. davidiana has 2n = 34, NF = 66, and NFa = 62. The X chromosome was large and metacentric and the Y chromosome was dot-like acrocentric. The 2 samples are different from each other, and from previous T. davidiana records, in terms of their lower incisor and premolar …


On The Occurrence Of Ascorhynchus Castelli (Dohrn, 1881) (Arthropoda: Pycnogonida) In The Aegean Sea, Cengi̇z Koçak Jan 2012

On The Occurrence Of Ascorhynchus Castelli (Dohrn, 1881) (Arthropoda: Pycnogonida) In The Aegean Sea, Cengi̇z Koçak

Turkish Journal of Zoology

Sampling studies in the Turkish Aegean Sea revealed the occurrence of a sea spider species, Ascorhynchus castelli (Dohrn, 1881). The presence of this species is reported for the first time from the Aegean Sea and the second time from the eastern Mediterranean Sea. This record further extends the known distribution of the species from the Turkish Mediterranean Sea to the Aegean Sea in the eastern Mediterranean. This is also the first record of the species from shallow waters in the eastern Mediterranean Sea (10 m).
