Abstract:

 


Edovum puttleri, an egg  parasitoid of Colorado Potato Beetle   (C.P.B.) was reared and parasitization ratio was determined in  laboratory conditions. The C.P.B. and the parazitoid were rared at 27±2ºC,  65±5%RH and 26±2ºC, 65±5%RH, respectively. On the other hand Bacillus thuringiensis (B.t.) preparations (M-ONE, MYX 1806,  Novodor) were tested on larval stages of the pest in laboratory and field  conditions. azinphos-methyl (Gusathion) was used as a standart product in the  tests. Field experiments were carried out three applications were done with one  week intervals. Alive larvae were counted one week after the applications. In  addition to this damaged plants were also evaluated after 14 days from the last  application. Parasitization ratio was found as 41.6%in laboratory. During  parasitization death ratio by probing was 15 - 75%.
  Total egg death ratio was found as 59 - 99.9%.
  Sexual ratio(female:male)  was found  as 2:1.

Patates  böceği (Leptinotarsa decemlineata Say)(Col.:Chrysomelidae)'nin biyolojik mücadele imkanlarını araştırmak amacıyla  laboratuvar koşullarında yumurta parazitoidi Edovum puttleri Grissel. (Hym.: Eulophidae) ile çalışılmıştır.  Çalışmalar sonunda parazitoidin laboratuvar koşullarında parazitleme oranı  ortalama %41.6 olarak bulunmuş, tarla koşullarında yapılan çalışmada ise  elverişsiz çevre koşulları (sıcaklık gibi) nedeniyle parazitlenme tespit  edilememiştir. Parazitoidin etkinliği çalışmasının yanı sıra ayrıca laboratuvar  ve tarla koşullarında zararlının larvalarına karşı Bacillus thuringiensis'li preparatlar denenmiş ve M-ONE (B.t. var. sandiego)'ın 500 ml/da MYX-1806 (B.t. var. sandiego)'in  280 ml/da ve Novodor (B.t. var. tenebrionis)'un 200 ml/da dozları etkili  bulunmuştur.
