“…Amongst insect pests, apple aphid (aphis pomi) and beetles (Altica foliaceae and Nemognatha scutellaris) were the most common insect pests of apple. Parallel to the finding by Milenković et al [15], throughout the assessed fields, apple aphid was severe on nursery seedlings and young plantations as succulent plant parts are more appealing to sucking insects. Moreover, aphid pressure was lessened in 2014 compared to the previous season.…”

Temperate fruits (Apple, Pear, Plum, Peach and Almond etc.) are deciduous fruit trees that grow well in temperate climate zones where most commercial varieties fulfill their required chilling temperature. Recently though, because of the low average temperatures, these crops are found to be grown well in the highlands of Ethiopia. Amongst the areas that have greater significance in this aspect is North Shewa zone, Amhara region of Ethiopia. Accordingly, aiming to get acquainted with the distribution, incidence, and severity of temperate fruit diseases and insect pests, a systematic survey was carried out in seven districts of North Shewa (Menz Gera, Menz mama, Basonaworana, Angolela Tara, Tarmaber, Ankober and Hagere Mariam) for two consecutive seasons. As revealed by the assessment, temperate fruit trees are subjected to numerous pests. Apple trees were found to be infested with apple scab, powdery mildew, canker, apple aphid, woolly aphid, beetles, spider mite and sting bug, whereas, leaf rust was the main disease of plum and peach. In most locations, apple scab, powdery mildew leaf rust, apple aphid and beetles were very much recurring and most destructive, therefore considered as economically important pests of temperate fruits in the area. Moreover, except for few conspicuous inconsistencies, the seasonal and altitudinal variation in distribution and severity of these diseases and insect pests were comparable.

“…A commonly used procedure aimed at controlling aphids is based on the application of synthetic insecticides [22] such as spirotetramat. This chemical is highly effective against various pest species, such as Dysaphis plantaginea, Eriosoma lanigerum, Aphis spiraecola and Aphis pomi [23].…”

Application of pesticides leads to contamination of the natural environment, which entails the necessity to seek solutions that use substances which do not pose ecological hazards. The presented investigations tested the efficacy of a preparation containing organomodified trisiloxane and a cross-linking agent (Siltac EC) to limit the number of two-spotted spider mite (Tetranychus urticae) on the leaves of raspberry (Rubus idaeus) and blackcurrant (Ribes nigrum), as well as the numbers of green apple aphid (Aphis pomi) on apple trees (Malus domestica). The high effectiveness (more than 90%) of Siltac against spider mite on raspberry and blackcurrant leaves was rapid and persisted at least by two-three weeks after spraying. There was observed an inhibition of pest developing (i.e. significant decrease of eggs and larvae). Similar effect occurred per an apple tree shoot and the number of living apple aphids was reduced by more than 93% in comparison to untreated trees. In all experiments, the effectiveness of Siltac was similar and usually longer lasting than control pesticides. Moreover, no phytotoxicity of the tested preparation was observed during the investigations. In conclusion, on the basis of the presented results it was found that Siltac EC could be a good alternative to the currently used plant protection chemicals.

Özet: Elma bahçelerinde ekonomik kayıplara neden olan birçok hastalık, zararlı ve yabancıot türü bulunmaktadır. Zararlılar içinde elma içkurdu, kırmızıörümcekler ve yaprakbitleri ana zararlılar arasında yer almaktadır. Elma üretiminin yoğun yapıldığı Isparta ilinde özellikle yağışlı geçen yıllarda yılda 20 kezden daha fazla ilaçlama yapıldığı bilinmektedir. Bu çalışmada söz konusu zararlılara karşı çevre ve yararlılara fazla etkisi olmadığı bilinen azadirachtin ve kaolinin etkisi 2015 yılında incelenmiştir. Denemeler Süleyman Demirel Üniversitesi, Ziraat Fakültesi bünyesinde bulunan 5 ve 2 dekarlık iki elma bahçesinde yürütülmüştür. Her bahçe dört parsele ayrılmış ve her bir parsele kaolin, azadirachtin (neem), karşılaştırma ilacı olarak chlorpyrifos-ethyl ve Kontrol parseline de su püskürtme şeklinde uygulanmıştır. Denemeler tesadüf blokları deneme desenine göre kurulmuş olup, her tekerrürde 8 ağaç olacak şekilde 6 tekerrürlü olarak düzenlenmiştir. Her hafta, her bir ağaçtan 40 yaprak örneği alınarak Tetranychus urticae, Pananychus ulmi, Aphis pomi ve Dysaphis plantaginea sayımları yapılmıştır. Elma içkurdu zararı ise hasat zamanında ağaç üzerinde ve yere düşen meyvelerde bulaşma oranına göre belirlenmiştir. Çalışma sonucunda yaprakbitine karşı en etkili Chlorpyrifos-ethyl bulunmuş, bunu kaolin ve neem izlemiştir. Preparatlar kırmızıörümceklere karşı benzer etki gösterirken elma içkurdu bulaşma oranları sırasıyla, kontrol parselinde %49.99, kaolin parselinde %42.27, neem parselinde %41.20 ve chlorpyrifos-ethyl parselinde %31.23 olmuştur. Effect of Azadirachtin and Kaolin Applications Against Some Important Pests in Apple OrchardsKeywords Azadirachtin, Apple, Kaolin, Integrated pest management Abstract: A lot of pests, diseases and weeds cause economic losses in apple orchards. Among them, codling moth, mites and aphids are the key pests. It is reported that more than 20 pesticide applications were made in the apple orchards in Isparta, especially in the rainy years. Experiments were carried out in two apple orchards 5 and 2 da each, in 2015. Each orchard was divided to four plots for the treatments of kaolin, azadirachtin (neem), Chlorpyrifos-ethyl and water for control. Applications were made by spraying onto the plants. Randomized complete blocks design was used with six replications and each replicate had 8 trees. Leaf samples were regularly collected from the plots every week and mites (Tetranychus urticae and Pananychus ulmi) and aphids (Aphis pomi and Dysaphis plantaginea) were counted. Codling moth infestation rate was determined by counting the infested fruits both on the trees and dropped ones at harvest time. As a result of the study, chlorpyrifos-ethyl was found to be the most effective pesticide against aphids and followed by kaolin and neem. While the test materials showed a similar effect against red spider mites, the infestation rates of codling moth were as follows; control plot (49.99%), kaolin (42.27%), neem (41.20%) and chlorpyrifos-ethyl (31.23%).
