Factors imparting resistance against the fruit and shoot borer Leucinodes orbonalis guenee infestation in brinjal crop- A review


Niv Dadhaniya, Pritha Ghosh, Dhruv Manvar

Brinjal, is an important solanaceous vegetable crop in the tropical and subtropical region which is sufficient in different essential elements. However, the production is threatened with several losses due to different factors. Amongst those, the shoot, and fruit borer (BSFB), Leucinodes orbonalis is one of the most limiting factors. The infestation of BSFB may result up to 70% of losses in brinjal across India. In vegetative phase, the caterpillar bore into terminal end of stem to the calyx. The caterpillar bore into young fruits through the fragile calyx tissue, leaving no clear evidence of infestation. Some eggplant varieties have distinct biophysical (viz., plant height, fruit shape, plant structure, fruit length, spines of leaves, fruit size, branches per plant, petioles, fruit skin width, calyx of fruits and shoot thickness, etc) and biochemical features (viz., moisture, sugars, mineral material, overall phenol, ash content, silica, etc) that Impart long term resistance of Brinjal shoot and fruit borer (BSFB). Long thin fruited brinjal cultivars were observed to be less damaged than circular fruited cultivars because the larvae bore more efficiently in round fruits. In a BSFB resistance breeding programme, the cultivar with the low calyx and pedicel, the low sugar, the high phenol and the high polyphenol oxidase, were used to develop a resistant cultivar. Genetic improvement in crop could also be utilized for resistance development in the brinjal crop. Expoitation of resistant genes (additive and non-additive) is very crucial to achieve an effective and well-organized breeding plan to improve resistance and crop production by combating this pest attack.
