The fatty acid compositions of predator Piocoris luridus （Heteroptera： Lygaeidae） and its host Monosteria unicostata （Heteroptera： Tingidae） reared on almond

The changes in fatty acid compositions during nutritional interaction among almond Amygdalus communis Linnaeus (Rosales: Rosaceae) (host plant), lacebug Monosteria unicostata (Mulsant and Rey) (Heteroptera: Tingidae) and its predator Piocoris luridus Fieber (Heteroptera: Lygaeidae) were determined by gas chromatography and gas chromatography‐mass spectrometry analyses. The fatty acid profiles of phospholipids and triacylglycerols were substantially different. Unlike the general observations for virtually most terrestrial insects, arachidonic and eicosapentaenoic acids were detected in high proportions of phospholipid fractions in both insects, especially in P. luridus. Also the almond tissues provide very little oleic acid to the herbivore diet, yet both insect species developed high proportions of this component. Our data reveals instances of specific accumulation of fatty acid biosynthesis, elongation/desaturation, and not incorporating selected fatty acids into cellular lipids.

Listrognathus mactator (Thunberg, 1824) (Hymenoptera: Ichneumonidae) — A New Recorded Parasitoid of Cimbex Quadrimaculatus (O. F. Müller, 1766) (Hymenoptera: Cimbicidae) in Turkey

ABSTRACT: Listrognathus mactator (Thunberg, 1824) (Hymenoptera: Ichneumonidae) was determined as a larva-pupa parasitoid of the almond pest, Cimbex quadrimaculatus (O. F. Müller, 1766) (Hymenoptera: Cimbicidae). The parasitoid is also recorded from Turkey for the first time.

A new host [Centaurea stapfiana (Hand.-Mazz.) Wagenitz (Asteraceae)] record for the moth Metzneria subflavella Englert (Lepidoptera: Gelechiidae) from Turkey

Abstract The present study was carried out in vineyard fields of Diyarbakır province, Turkey, in 2014 on Centaurea stapfiana (Hand.-Mazz.) Wagenitz (Asteraceae) infested with the larvae of moth Metzneria subflavella Englert (Lepidoptera: Gelechiidae). Metzneria subflavella were obtained from C. stapfiana flower buds collected in vineyard fields. C. stapfiana is a new host record for M. subflavella. In addition, this is the first record of M. subflavella from insect fauna of Turkey.

Malatya ili kayısı alanlarında zararlı Sphaerolecanium prunastri (Boyer de Fonscolombe, 1834) (Hemiptera: Coccidae) (Erik koşnili)'nin yayılış alanları, bulaşma oranları ve doğal düşmanlarının belirlenmesi

The study has been carried out by the technique of working in land and making observations performed as biweekly periods in march and november, with the aim of determining the distribution, infestation and natural enemies of Sphaerolecanium prunastri (Boyer de Fonscolombe, 1834) (Hemiptera: Coccidae) in the province of Malatya between the years of 2003 and 2004. In consequence of the study, it was determined that the S. prunastri was distributed in the Center, in the districts of Battalgazi, Kale Yazihan and Yesilyurt, which are located in the province of Malatya. In addition, it was detected that the infections higher in the district of Yazihan than it is in the other sampling areas. In the scope of the study which has been carried out in order to determine the natural enemies of the above mentioned pest, the Pachyneuron muscarum (L.,1758), Coccophagus lycimna (Walker,1839), Metaphycus sp., Exochomus quadripustulatus (L.,1758), Cybocephalus fodori minor (Endrody & Younga), Chrysopa sp. species and also Metaphycus sp. have been identified as the natural enemies of the pest.
