Abstract

Development and fecundity of Phyllocnistis citrella Stainton (Lepidoptera: Gracillaridae) were recorded at five constant temperatures ranging from 15 to 35±1°C in 5°C increments and a varying temperature of 25-35°C. Developmental time (egg to adult) of P. citrella decreased with increasing temperatures, ranging from 51.7 days at 15°C to 10.1 days at 35°C. The immature mortality was highest at 15°C and lowest at 30°C. No eggs were deposited at 15CC. At all temperatures studied the females lived statistically longer than the males. Net reproductive rate (Ro) was the highest at 30°C with 50.19 female/ female. The highest intrinsic rate of increase (rm) were 0.258 and 0.260 females/female/day at 30°C and 35°C, respectively, but they found at the same statistical group. Results concluded that a temperature of 30°C is optimal for P. citrella.

Özet

Beş sabit (15, 20, 25, 30, 35°C) ve bir değişken (25-35°C) sıcaklığın Turunçgil yaprak galerigüvesi, Phyllocnistls citrella Stainton (Lepidoptera: Gracillaridae)'nın gelişme ve üremesi üzerine etkileri araştırılmış ve bu sıcaklıklarda zararlının yaşam çizelgeleri oluşturulmuştur. Ergin öncesi toplam gelişme süresinin sıcaklık arttıkça kısaldığı, en uzun 15°C'de 51.7 gün en kısa da 35°C'de 10.1 gün olduğu belirlenmiştir. En fazla ölüm 15°C'de olmuş ve bu sıcaklıkta yumurtlamanın olmadığı saptanmıştır. En az ölüm ise 30°C'de olmuştur. Çalışılan bütün sıcaklıklarda dişi bireyler erkek bireylerden istatistiki olarak daha uzun yaşamışlardır. Net üreme gücü (Ro), en yüksek 50.19 dişi/dişi ile 30°C'deki bireylerde saptanmıştır. Kalıtsal üreme kapasitesi (rm) 30 ve 35°C'lerde sırasıyla 0.258 dişi/dişi/gün ve 0.260 dişi/dişi/gün olarak belirlenmiş ancak aynı istatistiki grupta yer almışlardır. Elde edilen sonuçlara göre P. citrella için optimum sıcaklığın 30°C olduğu kanaatine varılmıştır.
