Abstract Spodoptera frugiperda is a newly discovered pest in Indonesia. S. attacks can cause crop failure and significant losses. As preventive control measure, research was conducted to determine the most effective parasitoid controlling . This used egg parasitoids ( Telenomus remus Trichogramma chilotraeae) larval Microplitis manilae ). done by exposing 50 eggs of each ten larvae M. Ten repli...
5 to 10 days. At the end of that time it was noticed that in every case the plants containing the liver extract in solution were distinctly greener than the controls without the liver extract. Some factor in the liver extract has apparently checked the destruction of the chlorophyll; this destruction of chlorophyll goes on constantly, but in the daylight the pigment is constructed as fast as it...
Throughout the animal kingdom, Haller's rule holds that smaller individuals have larger brains relative to their body than larger-bodied individuals. Such brain-body size allometry is documented for all animals studied to date, ranging from small ants to the largest mammals. However, through experimental induction of natural variation in body size, and 3-D reconstruction of brain and body volum...
Three linkage maps of the genome of the microhymenopteran Trichogramma brassicae were constructed from the analysis of segregation of random amplified polymorphic DNA markers in three F2 populations. These populations were composed of the haploid male progeny of several virgin F1 females, which resulted from the breeding of four parental lines that were nearly fixed for different random amplifi...
ارزیابی قدرت پرواز از معیارهای کنترل کیفی زنبورهای پارازیتوئید می باشد. در این تحقیق تأثیر نسل روی قدرت پرواز زنبورtrichogramma brassicae بررسی شد. برای این منظور زنبورهای پارازیتویید با نصب تله های تخم حاوی بید غلات، sitotroga cerealella در مزارع برنج و جمع آوری تخم های کرم سبز برگخوار برنج naranga aenescens جمع آوری و هشت نسل متوالی در شرایط آزمایشگاهی روی تخم های بید غلاتپرورش داده شدند. آز...
