The biological and behavioural parameters of Anisopteromalus calandrae (Hym.: Pteromalidae), a parasitoid of Callosobruchus maculatus (Col.: Bruchidae) on Chickpea were studied in laboratory conditions at temperature of 25±1ºC, photoperiod 16:8 (L:D) and 20±5 % RH. The pre-adult period of the wasp was 19.82 ± 0.038 days and pre-ovipositional period in this wasp was so short that female laid egg...

  In order to evaluate insecticidal potential of some botanical extracts, a factorial experiment of complete randomized design with three replications on Callosobruchus maculatus was adopted for a pilot experiment in the laboratory. Plant extracts were prepared from 22 plants with three solvents (Methanol, Acetone and N-Hexane) with 30% concentration. Experiments were carried out at 25˚C and 70...

یکی از مهم­ترین مشکلات درختان کاج در پارک چیتگر، شیوع آفت سوسک پوست­خوار کاج،Orthotomicus erosus (Wollaston) (Col.:Curculionidae: Scolytinae)، است که علاوه بر خسارت مستقیم، به­ عنوان ناقل بیماری­ های مختلف نیز عمل می­ کند. به­ منظور مطالعه نوسانات جمعیت فصلی سوسک پوست­ خوار مدیترانه­ ای کاج، نمونه­ برداری حشره کامل از شاخه­ ها و تنه­ های درختان کاج آلوده از مناطق مختلف پارک چیتگر تهران...
