In this study, the effects of two different commercial neem insecticides (NeemAzal T/S and Neem Oil) were determined on different stages of Nezara viridula (L.) (Heteroptera: Pentatomidae) under laboratory conditions. Neem Azal and Neem Oil were applied at concentrations of 0.5 % and 2 %, respectively. Mortality was recorded after 3, 7 and 14 days for nymphs and adults; 7 and 14 days for old (4-day-old) eggs; and 14 days for newly laid (one-dayold) eggs.Both products have no significant effect on adults and newly laid eggs. However Neem Oil was found to be more effective than NeemAzal T/S on nymphs and on old laid eggs after 7 and 14 days.It can be concluded that both neem products have potential for insecticidal efficacy (approximately 60 %) against nymphs of N. viridula. at concentrations recommended by manufacturers for registered pests.

This study was carried out to contribute the Delphacidae, Tettigometridae and Cixiidae (Hemiptera) fauna in the East and Southeast Anatolia Region of Turkey. Specimens were collected from different locations of the study area, in 2007, 2008, 2014 and 2015, and prepared according to standard methods. 7 species belonging to 6 genera from 3 families were determined: Hyalesthes obsoletus, Pentastiridius leporinus, Laodelphax striatellus, Sogatella vibix, Toya propinqua, Tettigometra atra and Tettigometra macrocephala. Number of examined specimens, host plants and distribution of species in Turkey have been given. In these species; P. leporinus, L. striatellus T. atra, T. macrocephala were new records in these regions.

This study was carried out in order to determine spider fauna in olive orchards of Mardin province in 2009-2011 years. Steiner funnel was used for collect spider species on plant organs. In order to determine of spider species, 20 randomly selected trees (five branches per tree, 100 strokes in total) were made beating every 15 days from April to October. A total of 257 specimens belonging to 24 genera were collected. 12 of them were males, 30 were females and 215 were nymph. 26 species belonging to 11 families, Araneidae (4), Clubionidae (1), Dictynidae (1), Eutichuridae (1), Gnaphosidae (1), Linyphiidae (2), Philodromidae (1), Prodidomidae (1), Salticidae (7), Theridiidae (3) and Thomisidae (4), were determined. It has also been determined that these spider species belonging to families Salticidae (27%), Araneidae (15.5%), Thomisidae (15.5%) and Theridiidae (11.5%) were important in terms of their prevalence and abundance in olive gardens.

With this study, brief information about the new distribution area and economic importance of the Alphitophagus bifasciatus (Say, 1823) (Coleoptera: Tenebrionidae) is given. It has been found in cereals, oilseeds, and in their products such as copra, cocoa, nuts, feed, dried fruit, herbs, and spices in previous years. It is possible in the following years that it will be characterized as potentially harmful by causing economic damage in the paddy fields in the Eastern and Southeastern Anatolia Regions of Turkey. Determining the specimen in this region is important in terms of faunistic and economic entomology in order to investigate the agricultural control management in the countries where it is pest related to the species and to reveal the plant protection strategy.
