The present study was conducted during October 2014 to June 2015 in the farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to find out the most effective management option (s) against brinjal shoot and fruit borer (BSFB) with 6 treatments namely, Beauveria bassiana, 1109 CFU @ g l-1 , Bioneem 0.3 EC (Azadirachtin) @ 1.5 ml l-1 , Tracer 45 SC (Spinosad) @ 0.4 ml l-1 , Vertimec 1.8 EC (Abamectin) @ 1.2 ml l-1 of water, Mechanical control (hand picking) with clean cultivation and untreated control. Results revealed that shoot infestation at pre-fruiting stage was the lowest in Bioneem 0.3 EC (4.34%) and at fruiting stage in Tracer 45 SC treated plot (7.75%) and the highest was in untreated control plot (17.94% at pre-fruiting stage and 39.46 at fruiting stage). The lowest fruit infestation by BSFB was obtained with Tracer 45 SC (8.16% n/n and 10.0% w/w) followed by B. bassiana, 1109 CFU (23.23% n/n and 18.27% w/w) and the highest infestation was observed under untreated control plot (48.59% n/n and 32.09% w/w). Percent reduction of infested fruit by number (83.21%) and weight (68.84%) over untreated control was higher in Tracer 45 SC treated plot resulting significantly higher marketable yield. Therefore, the significant highest marketable yield (34.39 t ha-1) was harvested in the plot treated with Tracer 45 SC followed by 22.78 t ha-1 with B. bassiana, 1109 CFU and 19.26 t ha-1 from Vertimec 1.8 EC treated plot. The highest benefit cost ratio of 3.05 was obtained from Tracer 45 SC followed by 2.93 in B. bassiana, 1109 CFU and 2.89 with Vertimec 1.8 EC sprayed plot.

Brinjal (Solanum melongena Linnaeus) also known as eggplant is referred as the “King of vegetables” originated from India and now grown as a vegetable throughout the tropical, sub-tropical and warm temperate areas of the world. It is a most important vegetable in the Indian Subcontinent that accounts for almost 50% of the world’s area under its cultivation area under its cultivation. , in India, the area is estimated as 7.5% of the total area of vegetables with 8% of the total production of vegetables (Roy et al., 2016). Being high in economic value, now a day’s cultivation of brinjal is becoming the menace to the farmer because of the attack of the insect pest. Among the several problem that create obstacle for brinjal productivity and quality fruits, heavy losses caused by insect pests right from seeding stage till harvest. Vevai (1970) has reported that the 26 pests which International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 9 (2020) J...

Brinjal crop is regularly and simultaneously attacked by several insect pests like leafhopper (Amrasca bigutulla bigutulla Ishida), whitefly (Bemisia tabaci Gennadius) and brinjal shoot and fruit borer, Leucinodes orbonalis Guenee. The yield lossescaused are as high as 70-92% in India and the pest is reported to cause 3.3-68.9% damage to flowers and 47.6-85.8% damage to fruits in Orissa. The management of this pest is through calendar spraying of conventional insecticides irrespective of pest incidence. Insecticides suchas bio-pesticides, botanicals and chitin synthesis inhibitors, have been evaluated against L. orbonalis in the past and are being used. The bio-efficacy of thiodicarb (0.28125, 0.46875 and 0.75 kg a.i./ha) and other insecticides, i.e. Cartap hydrochloride [cartap] (0.5 kg a.i./ha), diflubenzuron (0.1 kg a.i/ha), carbofuran (1.0 kg a.i./ha) and Triazophos (0.5 kg a.i./ha) and Fipronil (0.1 kg a.i./ha), against brinjal shoot and fruit borer, Leucinodes orbonalis.

A field trial was conducted during 2017 and 2018 in kharif (rainy) season in farmers' participatory mode at randomly selected fields of farmers of Begusarai district as an on-farm trial under the supervision of Krishi Vigyan Kendra, Khodawandpur, Begusarai, Bihar in order to assess the bio-efficacy of plant products viz., oxymatrine, NSKE @ 5% and microbial formulation spinosad against shoot and fruit borer of brinjal Leucinodes orbonalis Guenee. This trial was conducted as a multi-locational trial at six farmers' fields as replications. The results revealed that four sprays of spinosad (45 SC @ 225 g a.i./ha) at 15 days intervals commencing at 30 days after transplanting (DAT) and clipping of infested shoots and picking of infested fruits was found to be most effective against shoot and fruit borer of brinjal followed by oxymatrine (1.2 EC @ 0.2%). Minimum percent shoot damage by borer was recorded with spinosad (13.5 and 13.83%) followed by oxymatrine (19.20 and 16.24%) in both years, respectively. Minimum percent fruit damage by borer was also recorded with spinosad (16.56 and 7.73%) followed by oxymatrine (23.36 and 10.10%) in both years, respectively. Maximum percent reduction of shoot damage by borer over control (farmers' practice) was recorded with spinosad (50.53 and 44.94%) followed by oxymatrine (29.64 and 35.35%) in both years, respectively. Maximum percent reduction of fruit damage by borer over control (farmers' practice) was recorded with spinosad (46.45 and 70.89%) followed by oxymatrine (24.47 and 61.97%) in 2017 and 2018, respectively. Yield, net return and BC ratio were also high in spinosad-treated plots as compared to other treatments and farmers' practices.

Brinjal (Solanum melongena) plays a vital role in the food of South-Asian people, thus the production of brinjal in these countries is quite high. However the production of brinjal does not satisfy the whole demand of people owing to the severe infestation by L. orbonalis. In order to get maximum yield from the cultivation farmers rely on over and indiscriminate use of chemical insecticides. Due to the side effects of over and indiscriminate use of toxic insecticides, now the trend moves towards Bio-intensive Integrated Pest Management (BIPM). The present study conducted to find the efficacy of BIPM over farmer's practices and untreated control in controlling the L. orbonalis. The study evidenced the superiority of BIPM in all aspects viz., lesser shoot infestation (15.82 percent), greatest yield (17,170.22 kg/ha) and higher natural enemies activities (5.25 no./10plants), which was equivalent to untreated control. Besides the treatment BIPM proved its efficacy over farmer's practice and untreated control especially with high percent increase of yield (63.90%), percent reduction of shoot (64.01%) and fruit infestation (80.58%), and less percent reduction of natural enemies' population (8.70%). Apart from this the benefit cost ratio (BCR) ranked in the order of superiority as BIPM module (1:5.75), which was greater than the farmer practice (1:4.96) on brinjal.

to study the effect of plant extracts for the management of brinjal (Singhnath) shoot and fruit borer (Leucinodes orbonalis Guenee) following Randomized Complete Block Design with three replications. Experiment consisted eight treatments viz. T : Tamarind fruit extract, T : Bon kolmi leaf extract, and fruit yield (36.2 t ha). Lower infested shoot and fruits (0.33 and 2.3 plant , respectively) and percentage 1 1 (2.2 and 9.3%, respectively) were also found in T while infested fruits weight and its percentage had also 4 lower (0.25 kg plant and 9.3%, respectively) in T. Protection of shoot and fruit borer had higher over control 1 4 (92.5 and 91.3%, respectively) and fruit yield increment over control had higher (61.7%) in T. Among the all 4 characters control treatment produced lower results in this study. Use of neem leaf extract was highly effective to reduce the shoot and fruit infestation as well as to get higher yield.
An experiment was undertaken to know the effectiveness of different biorational insecticides for controlling brinjal shoot and fruit borer (Leucinodes orbonalis Guenee) under field conditions during winter season 2017-18. The different treatments were Bioneem 1% EC (Azadirachtin 1000 ppm @ 1 mL L −1 (T1) Noclaim 5 SG (Emamectin benzoate) @ 1 mL L −1 (T2), Tracer 45 SC (Spinosad) @ 0.4 mL L −1 (T3), Suntec 1.8 EC (Abamectin) @ 1.2 mL L −1 (T4) and untreated control (T5). The results revealed that the treatments Spinosad (T3), Abamectin (T4) and Emamectin benzoate (T2) were effective to suppress brinjal shoot and fruit borer infestation in brinjal field. The rate of shoot infestation was observed 6.25% and 26.01% in Spinosad (T3) treated and control plot, respectively. The lowest fruit infestation (6.98%) by number and (9.32%) by weight was recorded in Spinosad (T3) treated plot. Reduction rate of fruit infestation over control was 82.82, 51.19, 41.15 and 38.17% by number and 66.11, 43.75, 33.13 and 24.44% by weight in Spinosad (T3), Emamectin benzoate (T2), Abamectin (T4) and Azadirachtin (T1), treated plot, respectively. The yield in different treatments ranged between 22.02 and 32.52 t ha −1 . Healthy fruits yield increase over control varied from 19.36 to 85.46%, where the highest increase was found in Spinosad (T3) treated plot and the lowest in Azadirachtin (T1). The highest adjusted net return and benefit-cost ratio (BCR) of Tk. 2,61,564 and 11.08, respectively were obtained from Spinosad (T3) treated plot. The lowest BCR was 2.66 in Azadirachtin (T1) treated plot. Among the four bio-rational inecticides Tracer 45 SC (Spinosad) showed the highest efficacy and it could be used against brinjal shoot and fruit borer in brinjal production.
