Research Article


Trichogramma is very minute insect which is being used in controlling the many insect pests. Due to the smaller size, the identification of different species of Trichogramma become complex work. In present study, Trichogramma chilonis and Trichogramma japonicum has been studied for its morphometric analyses. As a whole 33 characters of males and 27 of females have been studied. Parameters of different characters and their ratios have been analyzed by t test. In males of T. chilonis and T. japonicum, genital capsule length and width, longest flagellar hair length, fore and hind wings width, longest marginal fringe of fore and hind wings have been found to be useful in separating these two species. Similarly, females of these two species can be separated distinctly by morphometrics characters including ovipositor length, fore and hind wings width, antennal club length, longest marginal fringe of fore and hind wings. The details of parameters of different characters have been discussed.

We would like to thank Director, Forest Research Institute, Dehradun (Uttarakhand, India) for providing the necessary research facilities. We also like to thank Mr. Raman Nautiyal, ICFRE, Dehradun (Uttarakhand, India) for his kind help in statistical analysis of data. We are also greatly indebted to the authorities of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (Uttar Pradesh, India) for providing the culture of Trichogramma species for the study.
