This study was carried out to determine the natural enemies and distribution of Tingidae family species in Malkara, Saray, Süleymanpaşa, and Şarköy districts in Tekirdağ. Surveys were conducted on woody plants in 2011-2012. Field surveys were carried out at 10-day intervals between the beginning of April and the end of October. Visual inspection and shaking methods were used for sample collection. As a result of the surveys, as a natural enemy of Tingidae family species belonging Coleoptera order from the Coccinellidae family; Coccinella septempunctata (Linnaeus, 1758), Exochomus quadripustulatus (Linnaeus, 1758), Oenopia conglobata (Linnaeus, 1758), Stethorus gilvifrons (Mulsant, 1850), Hemiptera order from Anthocoridae family; Anthocoris nemoralis (Fabricius, 1794), Orius niger (Wolff, 1811), Orius vicinus (Ribaut, 1923), from Miridae family; Deraeocoris lutescens (Schilling, 1837), Stethoconus pyri (Mella, 1869) and Neuroptera order from Chrysopidae family; Chrysoperla carnea (Stephens, 1836), a total of 10 predatory species were identified. Erythmelus panis (Enock, 1909) from Mymaridae family of Hymenoptera order was determined as egg parasitoid. Stethoconus pyri was the most common species in Tekirdağ province, followed by C. septempuctata while A. nemoralis and S. gilvifrons were the least common species, respectively. The distribution of natural enemies was almost similar to the rate of their presence. It has been determined that all natural enemies in the province feed on Stephanitis pyri (Fabricius, 1775) (Pear lace bug). O. conglobata with Monosteira unicostata (Mulsant & Rey, 1852), except the Pear lace bug; A. nemoralis, O. niger and O. vicinus were also recorded to feed on Corythuca ciliata (Say, 1832). Many of the detected natural enemies are the first record for Tekirdağ fauna. Among these species, according to the observations and the data obtained, S. pyri feeding on Pear lace bug and Orius species feeding on C. ciliata are thought to be more important than other natural enemies. Therefore, in future studies, it would be more appropriate to investigate the biology and activities of these species in laboratory and/or field conditions. [ABSTRACT FROM AUTHOR]

This study was carried out to determine the population fluctuation and predators of Tinocallis (sappocallis) saltans (Nevsky, 1929) (Hemiptera: Aphididae) found to be intensely damaged in the Elm (Ulmus glabra Hudson) plant in Erzurum (Atatürk University Campus) between May and September in 2016 and 2017. T. saltans was determined for the first time on this elm species in Turkey with this study. Elm tip shoots were taken from the area at 4 days intervals and brought to the laboratory condition and adults and nymphs counts were made in this study. In addition, predator species were collected with the help of aspirator, atrap and Japanese umbrella. Pre-adult periods of predator species were brought to the laboratory together with the shoots and adult outputs were obtained by culturing. At the end of the study, T. saltans in July 27 (56.83 adult+nymph), 4 August (52.32 adult+nymph) and 24 August (47.66 adult+nymph) in 2016, and 12 August (39.36 adult+nymph) in 2017, has reached the highest number of individuals per leaf. A total of 12 predators from 4 Coccinellidae (Adalia bipunctata (L.), Adalia fasciatopunctata revelieri Mulsant; Coccinella septempunctata (L.), Harmonia quadripunctata (Pontoppidan) of Coleoptera; 1 Anthocoridae (Orius horvathi Reut.), 1 Nabidae family (Nabis pseudoferus Rem.) of Hemiptera; 5 Syrphidae (Episyrphus balteatus (De Geer), Eristalis pratorum (Meigen), Sphaerophoria rueppelli (Wiedemann), Sphaerophoria scripta (L.), Syritta pipiens (L.) of Diptera; 1 Chrysopidae (Chrysoperla carnea (Stephens)) of Neuroptera were identified in this study. Of these species respectively, A. f. revelieri (39 individuals), H. quadripunctata (21 individuals), C. semtempunctata ve Ch. carnea (16 individuals) and E. balteatus (14 individual) were the species with the highest number of individuals. T. saltans for all of these predator species were determined as the new host for the first time in this study in Turkey. It is great importance to consider these predators in these insect-control studies. [ABSTRACT FROM AUTHOR]

This study was conducted at the Experimental Area of Nazilli Cotton Researh Institute in second crop cotton season in years, 2015-2017. It was aimed to determine different doses of nitrogen fertilizer (0, 70, 140 and 210 kg N ha-1) on abudance of pests and their predators. Özbek 105, Gloria, Julia and Lydia cotton varieties were used as cotton varieties. As a result of the pests observations in the study, the variations of population densities of the pest species Aphis gossypii Glover (Hem.: Aphididae), Empoasca decipiens Paoli + Asymmetrasca decedens (Paoli) (Hem.: Cicadellidae), Bemisia tabaci (Gennadius) (Hem.: Aleyrodidae), Thrips tabaci Lindeman (Thy: Thripidae) and Tetranychus urticae Koch (Acarina: Tetranychidae) were assessed for the different nitrogen doses and cotton varieties. The increase at the amount of nitrogen dose has allowed an increase in population densities of the pest insects species in all cotton varieties studied. In the study, predatory species; Aeolothrips spp. (Thys.: Aeolothripidae), Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), Campylomma diversicornis Reuter (Hem.: Miridae), Nabis spp. (Hem.: Nabidae), Orius spp. (Hem.: Anthocoridae), Adonia variegata (Goeze) (Col.: Coccinellidae), Coccinella septempunctata Linnaeus (Coleoptera: Coccinellidae), Coccinella undecimpunctata Linnaeus (Col.: Coccinellidae) and Scymnus spp. (Col.: Coccinellidae) were identified. There was a positive relationship among the nitrogen doses and the population densities of the predators. In the light of the findings obtained from the study, the importance of fertilization in the control tactics performed against pest insects has been revealed. The application of nitrogen dose with (150 kg N ha-1) was recomended, leading economic and ecological production of cotton, and also creating a balance factor that limits the pest's population development in cotton.
