Özet
Bu çalışmada Türkiyedeki çam ağaçlarına zarar veren Çam kese böceğinin (Thaumetopoea wilkinsoni) tırtıldan pupaya ve pupa evresinden sonra ergin dönemine geçişinde boyutları ve ağırlıklarının etkisi olup olmadığı karşılaştırılmış ve incelenmiştir. Batı Karadeniz Bölgesindeki Düzce ilinde bulunan Düzce Üniversitesi kampüsünden Nisan ayında, böceğin toprağa girmek için kesesini terk ettiği dönemde tırtıllar toplanmıştır. Düzce Üniversitesi laboratuvarında Çam kese böceklerinin larva ve ergin dönemlerindeki ağırlık ve boyları ölçülmüştür. ÇKB tırtılları ağırlıklarına göre Küçük boy (<0-0,600 gr), Orta boy (0,601-0,900 gr) ve Büyük boy (>0,900 gr) olarak gruplara ayrılmıştır. Pupa oluşturmak için toplanan ÇKB' ne ait 5. gömlekteki tırtıllarından toplam 300 bireyin ortalama ağırlığı 0,752 gr ± 0,214 ve ortalama boyu da 3,12 cm ± 0,42 olarak hesaplanmıştır. Küçük olarak gruplandırılan tırtılların ortalama boyu 2,72 cm ± 0,29 ve ortalama ağırlığı 0,515 gr ± 0,071, orta olarak gruplandırılan tırtılların ortalama boyu 3,13 cm ± 0,22 ve ortalama ağırlığı 0,740 gr ± 0,094, büyük olarak gruplandırılan tırtılların ortalama boyu 3,53 cm ± 0,26 ve ortalama ağırlığı 1,001 gr ± 0,063 olarak hesaplanmıştır. Her gruptan 90 larva olmak üzere 270 larva ayrıca kontrol amaçlı rastgele seçilen 30 larva gruplandırılmadan tartılmış ve uzunlukları mm olarak ölçülmüştür. K1, K2, K3, O1, O2, O3, B1, B2, B3, Kontrol olmak üzere 10 adet deney ortamına bırakılmış ve toprağa girişleri takip edilmiştir. Toprağa girme zamanı başlangıç kabul edilerek (Nisan sonu) Eylül ayının sonuna kadar ergin evreye geçişi gözlemlenmiştir. Pupa olmak üzere toprak altına giren larvaların tamamı başarılı krizalit olamamıştır. Toplam 300 larvanın 175 adeti (%58) pupa evresine geçmiştir. Bu oran orta büyüklükteki grupta en fazla (%66) iken Kontrol grubunda en az (%33) olmuştur. Düzce ilinde Çam kese böceğinin ilk ergin çıkışı 16 Temmuz tarihinde görülmüştür. 1 Ağustos'ta son ÇKB ergininin pupadan çıktığı tespit edilmiştir. Toprağa pupa oluşumu sağlamak için konulan 300 larvadan 38 adet ergin ilk yıl için elde edilmiştir. Ergin olma başarısı ilk yıl için %13'tür. 10 adet küçük grubunda, 14 adet orta grubunda, 11 adet büyük grubunda ve 3 adet kontrol grubundan ergin çıkışı tespit edilmiştir. Zararlının ilk yılında en çok (0,601-0,900 gr) orta olarak ifade ettiğimiz ağırlıktaki ÇKB'nin ergin döneme geçtiği görülmüştür.
In this study, the effect of the size and weight on the transition from larva to pupa and from pupa to the adult stage of the Pine Processionary Moth (Thaumetopoea wilkinsoni), which damages pine trees in Turkey, has been compared and examined. In April, larvae were collected from the campus of Düzce University located in the Düzce province of the Western Black Sea Region, during the period when the larvae left their silk nests to enter the soil. In the laboratory of Düzce University, the weights and lengths of the larval and adult stages of the Pine Processionary Moth were measured. The Pine Processionary Moth larvae were grouped based on their weights as Small (<0-0.600 g), Medium (0.601-0.900 g), and Large (>0.900 g). The average weight of 300 individuals collected from the 5th instar larvae of the Pine Processionary Moth for pupation was calculated as 0.752 g ± 0.214, and the average length was 3.12 cm ± 0.42. The average length of the larvae classified as Small was 2.72 cm ± 0.29, and the average weight was 0.515 g ± 0.071. The average length of the larvae classified as Medium was 3.13 cm ± 0.22, and the average weight was 0.740 g ± 0.094. The average length of the larvae classified as Large was 3.53 cm ± 0.26, and the average weight was 1.001 g ± 0.063. In addition to 90 larvae from each group, a total of 270 larvae were randomly selected and weighed without grouping, and their lengths were measured in millimeters. Ten experimental environments, labeled as K1, K2, K3, O1, O2, O3, B1, B2, B3, and Control, were established, and their entry into the soil was monitored. The time of entering the soil was considered as the start (end of April), and the transition to the adult stage was observed until the end of September. None of the larvae that entered the soil to pupate were successful in becoming pupae. Out of the total 300 larvae, 175 of them (58%) transitioned to the pupal stage. This ratio was highest in the Medium-sized group (66%) and lowest in the Control group (33%). In Düzce province, the first emergence of the Pine Processionary Moth adults was observed on July 16th, and the last emergence from the pupa was detected on August 1st. Out of the 300 larvae placed in the soil for pupation, 38 adults were obtained in the first year. The success rate of becoming an adult in the first year was 13%. Adult emergence was observed in 10 individuals from the Small group, 14 individuals from the Medium group, 11 individuals from the Large group, and 3 individuals from the Control group. It was observed that in the first year of the pest, the Pine Processionary Moth with a weight categorized as Medium (0.601-0.900 g) had the highest rate of transitioning to the adult stage.
