Assessment of Rhynocoris Marginatus (fab.) (hemiptera: Reduviidae) as Augmented Control in Groundnut Pests
All the life stages of the reduviid predator Rhynocoris marginatus (Fab.) were released (30, 50 and 70 Days After Seedling Sowing -DAS) into the groundnut field at 5000/hectare. Spodoptera litura (Fab.), Helicoverpa armigera (Hubner), Atractomorpha crenulata, Chrotogonous trachypterus, Aphis craccivora, Mylabris pustulata and Mylabris indica were observed during the study period. R.marginatus s...
متن کاملDifferences on biological attributes of three populations of Meccus pallidipennis Stål (Hemiptera: Reduviidae).
BACKGROUND & OBJECTIVES Meccus pallidipennis is one of the most epidemiologically important vectors of Trypanosoma cruzi to reservoir hosts in nine states of Mexico. Triatomines occurring in distinct locations normally adapt to local conditions. The aim of this study was to examine the biological attributes of three populations of M. pallidipennis from areas with different environmental charact...
متن کاملUltrastructure of the fossula spongiosa and pretarsus in Haematoloecha nigrorufa (Stål) (Hemiptera: Heteroptera: Reduviidae: Ectrichodinae).
The ultrastructure of the fossula spongiosa and pretarsus of adult Haematoloecha nigrorufa (Stål) (Heteroptera: Reduviidae: Ectrichodinae) was examined for the first time using scanning electron microscope. The fossula spongiosa of H. nigrorufa is located on the ventral surface of the distal part of the tibia of both the fore- and midlegs. The area of the fossula spongiosa on the female foreleg...
متن کاملPreliminary Observations on Zelus obscuridorsis (Stål) (Hemiptera: Reduviidae) as Predator of the Corn Leafhopper (Hemiptera: Cicadellidae) in Argentina
The corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae), is an important corn pest in most of tropical and subtropical America. This leafhopper has a rich natural enemy complex of which parasitoids and pathogens are the most studied; knowledge on its predators is limited. We noted the presence of the native assassin bug Zelus obscuridorsis (Hemiptera: Reduviidae) predating diverse motile ...
متن کاملDescription and characterization of the melanic morphotype of Rhodnius nasutus Stål, 1859 (Hemiptera: Reduviidae: Triatominae).
INTRODUCTION For the first time we provide the description of the melanic (dark) morphotype of Rhodnius nasutus and determine the pattern of genetic inheritance for this characteristic. METHODS Dark morph R. nasutus specimens were crossbred with standard (typically patterned) R. nasutus. RESULTS We present the first occurrence of the melanic morphotype in the genus Rhodnius. The crossbreedi...
