Ceratitis capitata karantina zararlısı ve toleransı sıfır olarak kabul edilen bir türdür. Üreme kapasitesinin yüksek olması ve doğrudan meyvede zarar yapması nedeniyle zararlı ile mücadele yürütülmeden üretim yapmak mümkün olamamaktadır. Kimyasal mücadeleye alternatif olarak biyoteknik mücadele yöntemi olan kitle halinde tuzakla yakalama, zararlının çok yüksek olmayan popülasyonlarında başarılı sayılan bir mücadele şeklidir. Tuzaklar ile mücadelede farklı besin cezbedici materyaller kullanılarak bireylerin tuzağa çekilmesi sonucu öldürülmesi sağlanmaktadır. Bu çalışma, Ege ve Akdeniz Bölgelerinde şeftali bahçelerinde eş zamanlı yürütülmüş ve bölgeler arasındaki popülasyon farklılığına göre tuzakların etkinliğinin belirlenmesi amaçlanmıştır. Denemeler 2018 yılında Kuşadası (Aydın), Selçuk (İzmir) ve Erdemli (Mersin) ilçelerinde yürütülmüştür. Zararlının feromon tuzaklar ile popülasyon değişimi ve kitle halinde yakalama tuzaklarının etkinliği saptanmıştır. Mücadele tuzağı olarak Decis Trap (Bayer) isimli ürün kullanılarak tuzağın etkinlikleri saptanmıştır. Temmuz ayında Kuşadası, Selçuk ve Erdemli ilçelerinde sırasıyla 4.8, 149.1 ve 166.9 adet/tuzak ergin birey yakalamıştır. Buna göre Kuşadası ilçesinde %94.19, Selçuk ilçesinde %95.6 oranlarında etkili bir başarı sağlarken Erdemli ilçesinde %56.34 oranında etkili olmuştur. Akdeniz Bölgesi popülasyonunun Ege Bölgesine göre daha yüksek seyretmesi ve şeftali üretim sezonun daha uzun sürmesinden dolayı istenilen düzeyde başarı sağlanamadığı belirlenmiştir.

The important invasive thrips species Hawaiian flower thrips, Thrips hawaiiensis (Morgan, 1913) (Thysanoptera: Thripidae) was first reported in Türkiye in 2015. Since then, it has been causing damage in lemon orchards. This study was conducted to reveal the most effective insecticides, the most effective spraying time and the efficacy of biological control. For this purpose, the effectiveness of five insecticides (480 g/l spinosad, 25% spinetoram, 100 g/l spirotetramat, 50% flonicamid, 240 g/l tau-fluvalinate), effect of three spray programs and effectiveness of predatory bug Orius laevigatus (Fieber, 1860) (Hemiptera: Anthocoridae) were tested in a lemon orchard [Citrus limon (L.) (Rutales: Rutaceae)] in Erdemli district of Mersin province in 2018 and 2019. In order to determine the most effective spraying time, three spray programs were tested. In Program 1, two sprays during the flowering period were applied. In Program 2, two sprays were applied, one at petal fall and the other at the small fruiting stage. In Program 3, one spray at petal fall and two sprays in the fruiting stages were applied. According to the results, 240 g/l tau-fluvalinate and 50% flonicamid showed the lowest efficacy of the insecticides in the three programs. Spinetoram was found the most effective of the others. Insecticide applications to control T. hawaiiensis during the flowering period (Program 1) had low efficacy. Program 3 was found to be the most effective. Predatory bug O. laevigatus, as a biological control agent was found to have a potential efficacy for suppressing T. hawaiiensis populations.

Ceratitis capitata Wiedemann (Diptera: Tephritidae) is an important pest on the citrus, stone fruits and pome fruits in Eastern Mediterranean Region of Turkey. Three main methods are used to control the fruit fly populations in the region; i) mass trapping via bait station device, ii) pesticide bait spray mixture and iii) foliar pesticide application. The efficacy of the methods was evaluated in three different Okitsu Wase mandarin orchards during the fruit season (July-October) of 2015 and 2016 by monitoring the trapped number of the fruit fly in McPhail traps and counting C. capitata infected mandarin fruits. The fruit fly population level was very high at all mandarin orchard during the season. All the orchards have had more than 50 individuals per trap since the first week in the trials. The population continued increasing until the end of the August and hit the more than 700 C. capitata trap per week in malathion-bait spray applied orchards. The results show that three methods are not able to control the C. capitata population very well. Although foliar pesticide application has given better results with less infected fruits (4.4%) than other application methods in the first-year, mass trapping via bait station device (15.03%), and malathion bait spray mixture (15.15%) gave better result in the second year. As a conclusion, in high population level any of the methods did not ensure satisfied results, Therefore an integrated the fruit fly management tactics should be applied such a high population level.

Citrus rust mite, Phyllocoptruta oleivora (Ashmead) (Acari: Phyllocoptidae), is one of the most important pests of citrus fruit trees. In this study, the population density of P. oleivora was carried out on an orange orchard at Çukurova University (Balcalı-Adana) between 2013 and 2015. Ten leaves, one fruit and one twig were collected from 10 randomly chosen orange trees. The samples were taken every week between April and January while biweekly between January and April. As a result of these studies, the first individuals were observed in June. The highest population of P. oleivora on leaves was counted as average 57.25 in August. The last individuals on leaves were detected in January both year. The highest population of this mite on fruits was observed in August. The last individuals on fruits were counted between October and November both years. The highest population on twigs was observed as average 72.13 in the first week of January. The population of P. oleivora on twigs was reduced after May. Also, the population of P. oleivora was increased after light rainy days while was decreased after very rainy and cold days. The overwintering sites P. oleivora was observed as a twig. Also, Amblyseius swirskii, Euseius scutalis and E. stipulatus Athias-Henriot (Acari: Phytoseiidae) was detected as predator mite during the study. The low population of predator mite was observed when the high population of P. oleivora was present. Turunçgil pas böcüsü, Phyllocoptruta oleivora (Ashmead) (Acari: Phyllocoptidae), nem oranının yüksek olduğu pek çok turunçgil bölgesinde, başta limon olmak üzere portakal ve altıntopun ana zararlılarından biri konumundadır (Garzia and Lillo 2018, Satar et al. 2013, Uygun and Satar 2008). Bu phyllocoptidin kökeninin Güneydoğu Asya olduğu
