Brinjal (Solanum melongena L.) is the most important vegetable crop in the Asia Pacific region, with Pakistan being the seventh largest producer. There are many biotic and abiotic factors affecting its production in terms of quantity and quality including insect pests as a significant constraint. In Pakistan, the brinjal shoot and fruit borer, Leucinodes orbonalis is the major insect pest of brinjal. However, some other chewing and sap-sucking insects are also essential pests. Bt-brinjal, a transgenic variety, has been introduced in India and Bangladesh for the management of lepidopteran pests. Before the commercialization of transgenic brinjal in Pakistan, it must be assessed for its effects on the environment and non-target organisms. This study is presenting the overview of transgenic brinjal as an option to manage brinjal shoot and fruit borer along with current and future challenges in areas of its commercialization.

The present study on biochemical basis of resistance against Leucinodes orbonalis infestation was conducted during the year 2011-2012. The results revealed that highest chlorophyll-‘a’- content of 0.497 mg/gfw was recorded in the susceptible genotype SHB-1.The lowest amount of 0.319 and 0.381 mg/gfw was observed in the resistant genotypes Brinjal-85 and Local long respectively, which were significantly different from other evaluated genotypes. The chlorophyll ‘a’content was positively correlated with the brinjal shoot and fruit borer infestation. Thehighest chlorophyll -‘b’- content of 0.442 mg/gfw was recorded at 70 DAT (days after transplanting). The amount of chlorophyll -‘b’- varied significantly among the genotypes at different ages and decreased with the age of crop. The average highest amount of chlorophyll -‘b’- was estimated in the genotype SBH-1 which was significantly at par with hybrid SBH-2. The lowest chlorophyll -‘b’- content was recorded at 40 DAT in the genotype Brinjal-85 followed by Local Long. The lowest amount of total chlorophyll was estimated in the resistant variety as compared to susceptible therefore exhibiting lowest level of infestation.

Brinjal or eggplant (Solanum melongena L.) is widely grown vegetable in South and South-East Asian countries. There are various factors that limits the production of brinjal among which brinjal shoot and fruit borer (Leucinodes orbonalis Guen) is the most common one which occurs during the time at all the phases of the crop development. The damage caused by shoot and fruit borer (Leucinodes orbonalis L.) in brinjal begins immediately after transplantation of crop and growers will have to harvest an immature crop. The life cycle of BSFB completes in 19-28 days. It is estimated by various specialists that increase in the number of shoots per plant will lower the attack rate of the pest. Round shape fruits are more susceptible compared to long bodied fruits. It is also examined that total sugar contents increase the attack while total phenol contents produce resistance to pest. The information of nature and relative extent of gene exploit (additive and non-additive) is of key importance in scheming appropriate and well-organized breeding plan for enhancement of resistance and crop yield. Physical and chemical features, for example, plant structure, fruit form, spines of leaves, branches, petioles, calyx of fruits, fruit skin thickness and shoot thickness, synthetic traits, for example, ash, crude fibre, silica, sugars, mineral ingredients, total phenol contents of fruit and shoot of brinjal are examined to be included towards the shoot and fruit borer resistance in brinjal.Int.
