Abstract

Planococcus citri is an important pest that is common in many parts of the world and feeds on more than 200 plant species. It attacks the leaves, shoots and fruits of the pumpkin (Cucurbita moschata) plant, which is among its hosts, causing significant crop losses. In this study, development, survival and fecundity data of P.citri were obtained on the leaves of the pumpkin plant were in the climatic room which was adjusted to 28 ± 1 °C temperature, 60 ± 5% relative humidity and 16: 8 light: dark conditions. The raw data obtained were tested according to the age-stage twosex life table and the life table parameters were calculated using the Twosex MSChart package program. Accordingly, they were calculated as follows; the intrinsic rate of increase (r) = 0.0802 d-1, the finite rate of increase () = 1.0836 d-1, the net reproductive rate (R0) = 29.231 eggs, and the mean generation time (T) = 42.10 days. In addition, the population size of the pest was estimated using the Timing MSChart program. According to this, when 10 P. citri eggs were taken as the initial population, it was estimated that the population that could occur at the end of 3 months would be 4 137 individuals in total.

Özet

Planococcus citri, dünyanın birçok bölgesinde yaygın ve 200’den fazla bitki türü üstünde beslenen önemli bir zararlıdır. Konukçuları arasında olan kabak (Cucurbita moschata) bitkisinin hem yaprak ve sürgünlerine hem de meyvesine saldırarak önemli ürün kayıplarına neden olmaktadır. Bu çalışmada 28 ± 1 °C sıcaklık, % 60 ± 5 orantılı nem ve 16:8 aydınlık: karanlık şartlarına ayarlanmış iklim odalarında, P.citri’nin kabak bitkisinin yaprakları üstünde gelişme, canlılık ve üreme oranlarına ait biyolojik verileri elde edilmiştir. Elde edilen ham veriler yaş ve döneme özgü iki eşeyli yaşam çizelgesine göre test edilmiş ve yaşam çizelgesi parametreleri Twosex MSChart paket programı kullanılarak hesaplanmıştır. Buna göre kalıtsal üreme yeteneği (r) = 0.0802 gün-1, artış oranı sınırı () = 1.0836 gün-1, net üreme gücü (R0) = 29.231 yumurta, ortalama döl süresi (T) = 42.10 gün olarak hesap edilmiştir. Çalışmada ayrıca Timing MSChart programı kullanılarak zararlının popülasyon büyüklüğü tahmin edilmiştir. Buna göre, başlangıç popülasyonu olarak 10 adet P. citri yumurtası alındığında, 3 ayın sonunda meydana gelebilecek popülasyonun toplam olarak 4 137 birey olabileceği tahmin edilmiştir.
