Genetic diversity assessment in physic nut (Jatropha curcas L.)

Mahalanobis’ D-square (D2) statistics was applied to assess diversity in the 9 genotypes collectedof semi-arid region of India (7 genotypes from Gujarat and Rajasthan for normal toxic and two fromOrissa csmcri’s plantation of non toxic nature. These genotypes were grouped into five. Cluster I andIII had two genotypes, cluster II had three genotypes and cluster VI and V contributed as solitaryge...

BIOLOGICAL CONTROL Relationship Between Temperature and Developmental Rate of Stethorus punctillum (Coleoptera: Coccinellidae) and Its Prey Tetranychus mcdanieli (Acarina: Tetranychidae)

Temperature affects insect and mite development, allowing species-speciÞc traits including optimal temperature and low and high temperature thresholds to be observed. Development rate models and biological parameters estimated from them can help determining if synchrony exists between pests and natural enemies. We studied development of the coccinellid Stethorus punctillum Weise and the spider ...

Alternative control of Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae) on tomato plants grown in greenhouses.

Tetranychus evansi Baker & Pritchard is an important pest of solanaceous plants, including tomatoes. This mite is characterized by a high reproductive rate, which leads to high population growth in a short period of time causing important economic damage. Control of T. evansi is mainly through synthetic acaricides. In searching for environmentally friendly control measures, we evaluated the eff...
