Evaluation of Resistance in Brinjal (Solanum melongena L.) against Brinjal Shoot and Fruit Borer (Leucinodes orbonalis Guen.) Infestation: A Review

Abstract

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.

Chemical ecology of Himalayan eggplant variety's antixenosis: identification of geraniol as an oviposition deterrent against the eggplant shoot and fruit borer

“…Some investigators searched for the resistance factors among the physicochemical properties of the varieties showing relatively less infestation. They reported morphological characters like spines (Shaukat et al ., 2018), trichomes (Panda & Das, 1974; Javed et al ., 2011), and silica deposition (Kale et al ., 1986) and contents of metabolites such as steroidal alkaloids (Doshi et al ., 1998; Preneetha, 2002; Jat & Pareek, 2003; Thangamani, 2003), phenolics (Kale et al ., 1986; Asathi et al ., 2002; Prabhu et al ., 2009), and crude fiber (Kale et al ., 1986) as putative SFB‐resistant factors. However, most of these findings were based on correlative analyses and did not empirically validate the specific resistance factors for direct use in SFB management (Shaukat et al ., 2018; Lalita & Kashyap, 2020).…”
