An investigation was carried out to evaluate the insecticidal activity of Allium sativum, Zingiber officinale and Nigella sativa extracts against the larvae of T. granarium under laboratory conditions in the University of Agriculture, Faisalabad, Pakistan during 2009-10. The highest concentration of (6 %) Z. officinale was found to be comparatively more toxic (16.70 %) than those of A. sativum ...

Plants are the natural factories for the synthesis of variety of bioactive compounds. This diverse chemical setup of the plants speaks their important role as biomedicine. These biomolecules are often toxic to both plants and animals. The methanolic extract of Calendula arvensis was screened for its toxic potential against Lemna minor, Artimia salina (Brine shrimps) larvae and some important gr...

The leaves of parthenium (Parthenium hysterophorus L.) were extracted in ethanol and toxicity the extract was examined on khapra beetle (Trogoderma granarium Everts) larvae. Four concentrations (2, 4, 6 8 µL mL-1 acetone) applied directly larvae Petri dishes. Toxicity recorded after 12, 24 36 h. All had considerable effect mortality At highest concentration (8 mL-1), observed 57%, 72% 78% h, re...

The khapra beetle, Trogoderma granarium is a serious pest of stored grains in many nations. Larvae T. may be persistent warehouse conditions due to the ability enter facultative diapause. Thus, better understanding their behavior with respect movement as they seek places refuge or food lead improvements development monitoring tools and control technologies. distance that beetle larvae walk on v...
