Abstract

In this study, larval stages of Citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), which Citrostichus phyllocnistoides Narayanan (Hymenoptera: Eulophidae) prefers for parasitization and its functional and numerical responses were studied in 2008-2009. The larval stage preference studies were conducted in conditions with I., II. and III. larval stages of the pest together and each larval stages seperateIy in the cages. Determination of functional response was studied with mated one day old female parasitoids with 5, 10, 15, 20, 25, 30, 35 and 40 P. citrella larvae density. In numerical response studies, 2, 4, 6, 8, 10 ve 12 individuals of mated one day old C. phyllocnistoides females were released to potted seedlings which had 30 P. citrella larvae on it. It was conducted that C. phyllocnistoides mostly preferred the III. larval stage for egg laying both all P. citrella larval stages seperate or together. In reply to increasing host population density, the number of eggs laid by parasitoid increased parallel to increasing host density until 30 host individuals. The speed of the laying egg became slower over this level. It was determined that the parasitoid demonstrated a Holling type II functional response to increasing host density. According to Holling’s disk equation, searching rate (a) and the handling time (Th) coefficients of the parasitoid were 0.571 h-1 and 0.0997 h, respectively. In numerical response studies, the maximum parasitization was determined at six parasitoid density with 16.53±0.22 individuals

Abstract

Bu çalışmada, Citrostichus phyllocnistoides Narayanan (Hymenoptera: Eulophidae)'in konukçusu Turunçgil yaprak galerigüvesi, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae)’nın parazitlemek için hangi larva dönemini tercih ettiği ile işlevsel ve sayısal tepkileri 2008-2009 yıllarında araştırılmıştır. Larva dönemi tercih çalışmaları, P. citrella’nın I., II. ve III. larva dönemlerinin ayrı ayrı ve bir arada bulunduğu kafes çalışmalarıyla yürütülmüştür. İşlevsel tepkinin belirlenmesi C. phyllocnistoides'in çiftleşmiş bir günlük dişi parazitoitleriyle, P. citrella’nın 5, 10, 15, 20, 25, 30, 35 ve 40 larva yoğunluklarında çalışılmıştır. Sayısal tepki çalışmalarında ise P. citrella’nın 30 adet larvasının bulunduğu fidanlara C. phyllocnistoides’in çiftleşmiş bir günlük dişilerinden 2, 4, 6, 8, 10 ve 12 adet bırakılmıştır. C. phyllocnistoides’in, P. citrella’nın larva dönemlerinin ayrı ayrı ve bir arada bulunduğu durumda yumurta bırakmak için konukçusunun en fazla III. larva dönemini tercih ettiği saptanmıştır. Parazitoitin bıraktığı yumurta sayısı artan konukçu yoğunluğuna paralel olarak 30 konukçu yoğunluğuna kadar artmış, bu yoğunluktan sonra yumurta bırakma hızı azalmıştır. Parazitoitin artan zararlı yoğunluklarına gösterdiği işlevsel tepki tipinin, Holling’in tip II modeline uyumlu olduğu belirlenmiştir. Holling’in disk denklemine göre parazitoitinarama (a) ve parazitleme kapasitesi (Th) değerleri sırasıyla 0.571 sa.-1 ve 0.0997 sa. olarak bulunmuştur.  Sayısal tepki denemelerinde en yüksek parazitlenme altı parazitoit yoğunluğunda 16.53±0.22 birey olarak belirlenmiştir
