The red palm weevil Rhynchophorus ferrugineus (Olivier) is the most serious pest of palms in Turkey. Weevil infestation was first detected in Turkey in summer 2005 in parks and gardens of Mersin province, along the Mediterreanean coast of Turkey. Following the discovery of the pest, destruction of infested plant material, prophylactic insecticide chemical treatments, as well as adult weevil trapping were carried out on palm plantations. Traps containing a commercial aggregation pheromone were hung on palm trees at a high density, in order to monitor the pest infestation and reduce the weevil population by mass trapping. A significant decrease in the number of trapped beetles and destruction of infested plant material was observed in 2009 and continued in the following years in several cities in Turkey. Therefore, it has been observed that mass trapping and curative pesticide applications have played a significant role in the suppression of R. ferrugineus populations in palm plantations.

Phoenix theophrasti is the only palm species native to Turkey and it exists in small numbers in only a few locations along the Mediterranean Coast. Other Phoenix species and other palms are mainly grown in Turkey for environmental and ornamental purposes in house gardens, public gardens, parks and as street plantings. The common usage of palms in landscaping highlights their economic importance for the country, especially in coastal tourism areas. Date palms grown in Turkey produce fruits which are small in size, of low nutritional value and with little sugar content due to insufficiently warm temperatures to ripen fruit. Adult date palm trees were imported into the country, mainly from Egypt, until 2005, when imports ceased to prevent further introduction of red palm weevil, Rhynchophorus ferrugineus, which has become a serious threat to Phoenix and other palms. The other major insect problem is red palm scale insect Phoenicococcus marlatti. Measures are being taken to control these two pests. The limiting of palm imports has stimulated seed propagation of palms within Turkey.

ÖzBu çalışmada, ülkemizde domateste ilk olarak saptanan Lasioptera cinsine ait zararlının tanımı, zarar şekli ve bu zararlıya ait gözlemlere yer verilmiştir. Ayrıca zararlının Akdeniz Bölgesi'nde yayılış alanları belirlenmiştir. Zararlı ilk olarak 2011 yılı Mayıs ayında, Mersin ili Erdemli ilçesinde toplam 6 da'lık iki serada tespit edilmiştir. 2014-2015 yıllarında yapılan çalışmalarda ise zararlı, ayrıca Mersin ili Silifke ilçesi, Antalya ili Kepez, Kaş, Demre ve Aksu ilçelerinde de belirlenmiştir. Bu türün zararı genellikle koltuk alma işlemi sonucu açılan yaralar veya gövdede herhangi bir neden sonucu oluşan yaralardaki kalluslar üzerinde, yaprakların dip kısımlarında yada yaralanmış gövdelerde görülmektedir. Larvalar gövdenin öz kısmında beslenerek bitki dokusunda bozulma ve oyuklara neden olmaktadır. Gövdenin öz kısmında, kahverengi ve koyu gri renklenme biçiminde görülen zararlanmalar, 5-6 cm'ye kadar uzayabilmektedir. Bitki dokusu içerisinde beslenmesi nedeniyle mücadelesinin zor olan bu zararlının yayılmasının önlenmesi ve bu konuda özellikle iç karantina tedbirlerinin uygulanması, yoğun olarak görüldüğü alan olan seralarda bulaşıklığın önlenmesi için havalandırması iyi ve pencereleri tül ile kapatılmış yüksek modern sera yapımının özendirilmesi ve mücadelesiyle ilgili çalışmaların yapılması önerilmektedir.Anahtar kelimeler: Lasioptera sp., Domates, Zararlı, Cecidomyiidae, Sera A new tomato pest, Lasioptera sp.

Melanagromyza sojae Zehntner (Hemiptera: Agromyzidae) is known as a pest of several leguminous plants, especially Glycine max, soybean, in several countries worldwide. As a result of an alert raised by soybean producers in the province of Adana, which has a large share of soybean production in Turkey, plant samples in which pupae were observed were collected from two soybean fields in Çukurova in the production season in 2018. The samples were kept in the laboratory and the emerging adults were identified morphologically as M. sojae. Observations made in soybean fields in Turkey are presented. A review of the situation for this pest and its control methods are is presented. This is the first report of M. sojae in Turkey. It is therefore recommended to perform a close monitoring of this pest to investigate more in detail the extent of the damage caused by this pest in soybean crops in Turkey, to identify its variety preferences, other other hosts, natural enemies and control methods to be used.

Lasioptera sp. is one of the problematic pests in the Mediterranean and Aegean regions where protected tomato cultivation is done in Turkey. The larvae that cause tunnel and deteriorations in the plant's main stem by feeding on the core part of the body mostly lead to the death of the plant in a dense pest population.Since harmful larvae live in plant tissue and thus are protected against insecticides and biological agents, control of the pest is very crucial. As an alternative method to pest control, the effects of tomato axillary shoot pruning for controlling the pest were examined. For this purpose, while pruning of axillary shoots in tomato plants as recommended in cultural processes, shoots that are cut off from the body completely and stub-pruning sprouts with 3-5 cm length were assessed in the experiment. The study was carried out in Erdemli district of Mersin province in 2015 and 2017. Although it is ensured that the harmful larvae can feed inside stubpruned shoots left on the body, the larvae could not reach the plant's main stem and do not cause any damage to the plant. In terms of damaged plants, it was determined that 77.8% and 85.2% of the stub-pruning application are effective in 2015 and 2017, respectively. Additionally, in the study, the attractiveness of visual sticky traps in six different colors including, yellow, black, blue, white, red, and green was investigated. As a result of the study, it was concluded that the colors tested were not sufficient to attract pests.
