Bioefficacy of different species of entomopathogenic fungi against white grub, Leucopholis lepidophora (Blanchard) infesting sugarcane in Maharashtra

Biocontrol Potential of Entomopathogenic Nematodes Heterorhabditis and Steinernema Against Second Instar Grub of White grub, Leucopholis lepidophora (Blanchard)

The effectiveness of two entomopathogenic nematodes (EPN) viz., Heterorhabditis indica strain NBAII-104 and Steinernema carpocapsae strain NBAII-04 against second instar grubs of L. lepidophora (Blanchard) under pot culture experiment. At a concentration of 450 IJs ml, H. indica recorded highest mortality (87.60%) at 15 DAT. While, S.carpocapsae recorded 54.05 per cent grub mortality at 450 IJs...

Use of Radiography in Behavioral Studies of Turfgrass-Infesting Scarab Grub Species (Coleoptera: Scarabaeidae)

The behavior of turfgrass-infesting scarab grubs in response to soil physical properties may affect the stress that each species exerts on turfgrass and the efficacy of control tactics. To gain a more realistic picture of the events that occur within the soil matrix, we have developed a nondestructive X-ray technique to study soil insect movement and behavior in simulated and natural soil block...

Selection of Isolates of Entomopathogenic Fungi and the Bioefficacy of Their Liquid Production against Leptocorisa oratorius Nymphs

Entomopathogenic fungi are fungi pathogenic to insects and are widely used as biocontrol agents for insect pests. The aim of this research was to study the virulence of Beauveria bassiana and Metarhizium sp. isolates and to evaluate the efficacy of liquid production of those fungi against Leptocorisa oratorius (rice bug). Twelve isolates of B. bassiana and five isolates of Metarhizium sp. were ...

Comparative effects of entomopathogenic fungi and nematodes and bacterial supernatants against rice white tip nematode

The rice white tip nematode, Aphelenchoides besseyi, is the primarily important seed-borne pest of rice and was first recorded in Turkey in 1995. These biological agents, such as an entomopathogenic fungus (EPF), entomopathogenic nematodes (EPN), and bacterial supernatants, have been used against other plant parasitic nematodes but as far as not against A. besseyi. Accordingly, the EPF species,...

Preliminary study on virulence of some isolates of entomopathogenic fungi in different developmental stages of Boophilus annulatus in Iran
