| Abstract | The eggplant or brinjal (Solanum melongena L.) is one of the most important solanaceous vegetables in South-East Asian countries. The major brinjal growing states in India are Andhra Pradesh, Karnataka, West Bengal, Tamil Nadu, Maharashtra, Orissa, Uttar Pradesh, Bihar and Rajasthan. Globally, India ranks second and China ranks first in the production of brinjal (57.9% of world output). In India, this crop occupies 71.13 lakh hectare area along with annual production of 135.57 (lakh tone) and productivity 19.1 MT per hectare. In Uttar Pradesh, the area under cultivation of brinjal is 3430 hectare producing 111.70 MT and the productivity is 8 MT/ha (Anonymous, 2013). Hence, it is subjected to attack by number of insect pest’s right from nursery stage till harvesting (Regupathy et al., 1997). Among the insect pests infesting brinjal, the major insect is the shoot and fruit borer, Leucinodes orbonalis (Guen.). The major constraints in economic cultivation of brinjal, insect pest infestation are a major bottleneck which poses threat for its production (Kaur et al., 2014). Mall et al. (1992) reported that the shoot and fruit borer (on shoot) were more prevalent during vegetative phase of crop. The yield loss by this pest varied from 0.08-1.11 q/ha on the basis of inconsumable pest of damaged fruits and 0.463.80 q/ha when whole of the damaged fruits were taken into consideration. Singh et al. (2000) reported that the borer infestation was 78.66% on top shoots in vegetative phase and then shifted to flowers and fruits with infestation reaching 66.66% in fruiting phase. Several insecticides belonging to various groups such as synthetic pyrethroides, organophosphate, organochlorine and carbamate have been recommended for management of this pest in various part of country (Khaire et al., 1986; Pawar et al., 1987). However, their indiscriminate use have created several problems to ecosystem resulted in environmental pollution, pest resistance, pest resurgence, residual toxicity etc. (Kuppuswamy and Balasubramanian, 1980). Keeping in view the quantum of pesticides applied in brinjal crop in this region, the investigations were undertaken on evaluation of validity of efficacy of botanical insecticides against major insect pests of brinjal with the objective, to find out the efficacy of different botanical pesticides against shoot and fruit borer (L. orbonalis) of brinjal. |
