Assessment of the Sensitivity and Death Rates of Adults of Graphosoma lineatum (Linnaeus, 1758) Fed Chlorocholine Chloride, a Plant Growth Inhibitor, Under Laboratory Conditions

Chlorocholine Chloride’ın Graphosoma lineatum’un Ergin Bireylerinde Duyarlılık ve Ölüm Oranlarına Karşı Laboratuvar Koşullarında Araştırmalar

Abstract

The side effects of chlorocholine chloride, a plant growth inhibitor, on adults of Graphosoma lineatum were studied under laboratory conditions. In the study, 100, 250, 500, 750, 1000 and 1500 ppm of chlorocholine chloride in distilled water were applied. Chlorocholine chloride had killing effects on adults of G. lineatum. A 100% mortality of the male adults was observed after feeding 750, 1000 and 1500 ppm of the compound, whereas a 100% mortality of the females occurred with 1000 and 1500 ppm of the feeding compound. This study also showed that the sensitivity of the male adult insects to chlorocholine chloride was more than that of the females.

Özet

Bir bitki düzenleyici hormonu olan chlorocholine chloride’›n yan etkileri laboratuvar koflullarinda Graphosoma lineatum’un ergin bireyleri üzerinde araflt›r›lm›flt›r. Bu araflt›rmada chlorocholine chloride’›n 100, 250, 500, 750, 1000 ve 1500 ppm dozlar› saf su içerisinde kullan›lm›flt›r. Chlorocholine chloride'›n G. lineatum 'un ergin bireyleri üzerinde ölüm etkisi bulunmufltur. Erkek ergin bireylerde % 100 ölüm, 750, 1000 ve 1500 ppm dozlar›nda görünmüfltür. Buna karfl›n difli bireylerde % 100 ölüm 1000 ve 1500 ppm dozlar›nda bulunmufltur. Araflt›rma sonuçlar›na bak›ld›¤› zaman erkek bireylerin diflilerden daha duyarl› oldu¤u ›spatlanm›flt›r.
