“…In fact, this product had been intensively used in the Loukkos region during the last ten years resulting in the possibility of resistance development. Such an observation was also made by Ay and Gurkan (2005), who reported that bifenthrin became ineffective for controlling pests in the field, possibly due to resistance development. Due to the fact that most pyrethroids used against the mite were also used against other pests, T. urticae was strongly selected for resistance by the increased application of these pesticides (Herron et al, 2001).…”

Tetranychus urticae is one of the most important pests of strawberry cultures in Morocco. Current control of this pest relies almost exclusively on acaricides. Unfortunately, this mite has developed resistance to most of the available acaricides. Moreover, insecticide treatments are responsible for the reduction or suppression of beneficial species such as natural predators. Thus, identification of selective pesticides that are more toxic to pest species than on natural enemies, is urgently needed. This study assessed the effectiveness of abamectin, a microbial-based miticide, and bifenthrin, a synthetic one, on two-spotted spider mites, Tetranychus urticae and predatory mites, Phytoseiulus persimilis. Laboratory tests were conducted to determine the direct and residual effects of two miticides (abamectin and bifenthrin) at several doses in geometric progression. Firstly, the direct efficacy of the two acaricides was evaluated against T. urticae and P. persimilis. Abamectin had high efficacy on T. urticae and significantly less toxicity against P. persimilis. Results indicated an effective control of T. urticae, at least 2 weeks after abamectin foliar application. Thus, abamectin could be recommended as a selective acaricide in integrated mite management programmes because of its strong efficacy on pests, its persistence and its limited toxicity on predatory mites.Key Words: Tetranychus urticae, Phytoseiulus persimilis, abamectin, bifenthrin, acaricides efficacy, strawberry cultures RÉSUMÉTetranychus urticae représente le ravageur le plus important des cultures de fraises au Maroc. Le contrôle courrant de ce ravageur est presque relié à l'usage des acaricides. Malheureusement, cet acarien a développé une résistance à l'égard de la plupart des acaricides disponibles. En plus, les traitements aux insecticides sont responsables de la réduction ou suppression des espèces bénéfiques comme les prédateurs naturels. L'identification de pesticides sélectifs, plus toxiques sur les espèces de ravageurs que sur leurs ennemies naturels, est, de ce fait, urgemment recommandée. Dans l'étude décrite ici, nous avons testé l'efficacité de l'abamectine, un acaricide d'origine microbienne et la bifenthrine, un acaricide synthétique, sur les tétranyques à deux points Tetranychus urticae et sur les acariens prédateurs, Phytoseiulus persimilis. Des tests de laboratoire sont menés afin de déterminer les effets directs et résiduels des deux acaricides, appliqués en plusieurs doses variant selon une progression géométrique. L'efficacité directe des deux acaricides contre T. urticae et P. persimilis est évaluée. Nos résultats montrent que l'abamectine présente une haute efficacité sur T. urticae et une toxicité significativement moins importante à l'égard de P. persimilis. L'activité résiduelle des résidus des acaricides sur les acariens a, de même, été évaluée. Les résultats indiquent que l'efficacité de l'abamectine sur T. urticae persiste au moins deux semaines après son application sur les feuilles. Vue sa haute efficacité sur...

Isparta elma bahçelerinden toplanan SummaryThe spider mites are the second pest group which is tried to be managed in apple orchards following codling moth. The chemical control is generally preferred against spider mites. However, chemical control may lead to resistance in pests in the long time. The resistance development may lead to increase the pesticide usage. Because the dose and spray frequency of pesticides for the management of resistant pest population has been increased mostly. This study was conducted to determine the resistance against abamectin, chlorpyrifos ethyl and bifenthrin in Panonychus ulmi Koch (Acari: Tetranychidae) populations from apple orchards in Isparta. The LC50 values were determined in mentioned populations. The resistance ratios were determined dividing the LC50 values of susceptible population to the LC50 values of orchard populations. According to LC50 value, the resistance ratios against abamectin, chlorpyrifos ethyl and bifenthrin of P. ulmi orchards populations are 0.75-2.25, 0.57-1.76 and 1.19-3.78 fold, respectively. Key words: P. ulmi, apple, bifenthrin, abamectin, chlorpyrifos ethyl ÖzetElma bahçelerinde elma içkurdundan sonra en fazla savaşım yapılan zararlılar arasında kırmızıörümcekler yer almaktadır. Kırmızıörümceklere karşı genellikle kimyasal mücadele tercih edilmektedir. Fakat, kimyasal mücadele zaman içerisinde zararlılarda direnç sorununa yol açabilmektedir. Zararlılarda direnç gelişimi, dirençli zararlıları kontrol altına almak için daha yüksek dozlarda ve daha sık uygulamalar yüzünden daha fazla kimyasal kullanımına neden olmaktadır. Bu çalışma, Isparta ilindeki elma bahçelerinden toplanan Panonychus ulmi Koch (Acari: Tetranychidae) popülasyonlarında abamectin, chlorpyrifos ethyl ve bifenthrin'e karşı direnç düzeylerinin belirlenmesi amacıyla yapılmıştır. Toplanan popülasyonlarda bu akarisitlere karşı LC50 değerleri belirlenmiştir. Direnç oranları, bahçe popülasyonları için belirlenen LC50 değerlerinin hassas popülasyonun LC50 değerine bölünmesiyle elde edilmiştir. LC50 değerleri dikkate alındığında, bahçelerden alınan P. ulmi popülasyonlarının abamectin, chlorpyrifos ethyl ve bifentrin'e karsı göstermiş olduğu direnç oranları sırasıyla 0.75-2.25, 0.57-1.76 ve 1.19-3.78 kat arasında değişmiştir.Anahtar sözcükler: P. ulmi, elma, bifenthrin, abamectin, chlorpyrifos ethyl.

“…The important part of the APRD database concerns pyrethroids resistance in tetranychids. Today, this class of compounds accounts for 20% of the market, but the increasing number of cases of resistance to bifenthrin and other pyrethroids has been registered in the recent past (Herron et al, 2001;Ay and Gűrkan, 2005;Kumral et al, 2009;Tsakaragkou et al, 2009). As for other specific acaricides and insecto-acaricides, there is practically no active substance without documented cases of resistance, but there is an obvious difference in the scope of phenomenon between certain acaricides or groups of acaricides.…”

“…The insensivity of acetylcholinesterase is the most common type of organophosphorous resistance in T. urticae (Cranham & Helle, 1985;, Tsagkarakou et al, 2002Khajehali et al, 2010;Kwon et al, 2010a). Metabolic resistance mediated by carboxylesterases was found in majority of cases of resistance development to pyrethroids in this species (Ay & Gűrkan, 2005;van Leeuwen et al, 2005b, while the oxidative metabolism appears to play a major role in resistance to METI-acaricides Kim et al, 2004Kim et al, , 2006van Pottelberge et al, 2009). The results of numerous conventional genetic studies indicate that in most cases single major gene controls inheritance of resistance in spider mites (Cranham & Helle, 1985;.…”
