THE DISTRIBUTION AND POPULATION DENSITY OF THE CEREAL WEEVIL, PACHYTYCHIUSHORDEI (BRULLÉ) (COLEOPTERA: CURCULIONIDAE) IN CEREAL FIELDS IN NORTHERN CYPRUS

The Cereal weevil, Pachytychiushordei (Brulle) (Coleoptera: Curculionidae) is an important pest of barley and wheat. This study was conducted to determine the distribution areas and the population density of P. hordei in Northern Cyprus. The sampling were conducted in 57 cereal fields of 46 villages in Lefkoşa, Girne, Güzelyurt, Gazimağusa and İskele districts in 2012-2013 years. Sweep net were used in samplings. At the end of the study, P. hordei has been found common all in regions and the highest population densities were 379 adults/100 sweepnet and 247 adults/100 sweep net in Hisarköy/Girne in the years 2012-2013 respectively. In addition, damage states of P. hordei was evaluated

A new pest record for Capparis (Capparaceae) in Turkey and its larval parasitoids, Stiphrometasia sancta (Hampson, 1900) (Lepidoptera: Crambidae)

In this study, Stiphrometasia sancta (Hampson, 1900) which is from Crambidae family has been identified as harmful for Capparis ovata Desf. (Capparaceae). The biology of this species has been examined for the first time and research has been carried out on the harm of this species for the plant together with its larval food plant and nutrition style. Apanteles (Apanteles) subcamilla Tobias, 1976, Bracon hebetor Say, 1836, Chelonus canescens Wesmael, 1835 from Braconidae have been identified for the first time as larval parasitoid of S. sancta, and also A. subcamilla is a new record for Braconidae fauna of Turkey. © 2017, Gazi Entomological Research Society.

The species of Oopristus Steffan, 1968 (Hymenoptera: Torymidae: Toryminae: Monodontomerini) of Turkey, with descriptions of two new species [Türkiye'nin Oopristus Steffan, 1968 (Hymenoptera: Torymidae: Toryminae: Monodontomerini) türleri ve iki yeni türün tanımlanması]

The species of Oopristus Steffan, 1968 (Hymenoptera: Torymidae: Toryminae: Monodontomerini) of Turkey were studied. Oopristus turkestanicus (Skriptshinsky, 1929) was reared from the eggs of Apodiphus amygdali (Germar, 1817) (Hemiptera: Pentatomidae) in Balcali{dotless}, Adana, as a new record for Turkey. Additionally, 2 new species of the genus, O. tayfursokmeni Tarla and Do?anlar, sp. nov., and O. erganicus Tarla and Do?anlar, sp. nov., were described. The species were also reared from eggs of A. amygdali collected in Antakya, Hatay province, and Ergani, Diyarbaki{dotless}r province, respectively. The diagnostic characters of the species were illustrated and an identification key to species of the genus was provided. © TÜBİTAK

Predicting the development of critical biological stages of Sunn Pest, Eurygaster integriceps put. (Hemiptera: Scutelleridae), by using sum of degree-days for timing its chemical control in wheat

This investigation was carried out for possible use of sum of degree-days (total effective temperatures) in order to predict the critical biological stages in chemical control of Sunn pest, Eurygaster integriceps Put. (Hemiptera: Scutelleridae), in 28 wheat fields of Adıyaman, Diyarbakır, and Şanlıurfa provinces from 2007 to 2010, and in climate chamber conditions. Development threshold temperature (°C) of Sunn pest in terms of the life span, starting from egg to new generation of adults, was found as 13.30 °C. Sums of degree-days starting from 1 January to appearance of the eggs, first-stage nymphs (n1), second-stage nymphs (n2), and fourth-stage nymphs (n4) were found with the averages of 44.6, 84.4, 123.3, and 223.1 degree-days, respectively. The results from the field studies reflected that developmental biological data on sum of degree-days as a predictive tool could be useful in better decision making to start chemical applications as soon as the appearance of n1 until n4 for Sunn pest control. © TÜBİTAK

The determination of spider species (Araneae) in barley and wheat fields of Northern Cyprus

This study was carried out to determine the spider fauna in barley and wheat fields of Northern Cyprus. It was conducted in 36 cereal fields of 24 villages in the Lefkoşa, Girne, Güzelyurt, Gazimağusa, and İskele districts in the years 2012 and 2013. In the study, the Oxyopidae (2), Thomisidae (5), Salticidae (2), Araneidae (3), Philodromidae (2), Clubionidae (3), and Theridiidae (1) families from Araneae were determined. Seventeen of the 18 species, excluding Kochiura aulica (C. L. Koch), were found for the first time and included in the fauna of Northern Cyprus © TÜBITAK
