Mr. Y.B. SRINIVASA

 

Designation: Scientist-E

Qualification:

             B.Sc. (Agriculture) in 1993 from the University of Agricultural Sciences, Bangalore

             M.Sc. (Agriculture) in Entomology (1996) from the University of Agricultural Sciences, Bangalore

Thesis: Predatory potential of Cardiastethus affinis Poppius (Anthocoridae : Heteroptera) on the coconut black headed caterpillar, Opisina arenosella Walker (Oecophoridae : Lepidoptera)

 

Research Interests:

  1. Regulation of discrete generation cycles in aseasonal insects: Discrete generation cycles are common among insects in the temperate environment where the cycles are regulated by intense winters.  Populations that are not seasonal (aseasonal), such as those that live in the tropics, are expected to have overlapping generations.  However, from the past couple of decades evidences have been accumulating to support the presence of discrete generations among aseasonal insects.  We (with Dr. K. Muralimohan) are presently interested in understanding the underlying mechanisms that regulate discrete generation cycles in aseasonal insects.

  2. Passive interactions between plants and herbivorous insects: Ever since the coevolution theory (and the subsequent plant defense theories), interactions between herbivorous insects and their host plants have been largely viewed as ‘active’.  In spite of the problems associated with this theory, it continues to be popularly adopted for understanding insect-plant interactions.  On the contrary, I am interested in knowing if ‘passive’ resource-consumer models can explain some of the observed patterns involving herbivorous insects and plants.  Presently, I am interested in developing models for studying the influence of plant growth rate on the evolution of consumption rate among herbivores.
