The field experiments were conducted at ICAR Research Complex for North Eastern Hill Region, Umiam, Meghalaya, India during 2011-2012 to evaluate some biopesticides and newly introduced insecticides against shoot and fruit borer of brinjal. The experiments were laid out in Randomized Block Design (RBD) with three replications. The treatments viz., azadirachtin 1 EC (2 ml l-1), karanjin 2 EC (2 ml l-1), anonin 1 EC (2 ml l-1), Bacillus thuringiensis (Bt.) (2 g l-1), emamectin benzoate 5 SG (0.4 ml l-1), flubendiamide 480 SC (0.3 ml l-1), chlorantraniliprole 18.5 SC (0.4 ml l-1), chlorpyriphos 20 EC (2 ml l-1) were applied thrice at fifteen days interval starting from initiation of shoot and fruit borer infestation. Results showed that chlorantraniliprole (2.46%) was the best treatment in reducing the shoot infestation (81.88% reduction) which was statistically at par with flubendiamide (3.08%) and emamectin benzoate (3.76%) with 77.37% and 71.95% reduction over untreated control, respectively. The overall mean fruit infestation were also minimum in chlorantraniliprole (5.76%) and flubendiamide (5.93%) treated plots with 79.45% and 78.84% reduction over untreated control plots (28.03%), respectively. Pooled data of two years experimental results indicated that highest marketable yield was recorded in chlorantraniliprole treated plots (155.01 q ha-1) followed by flubendiamide (149.50 q ha-1), emamectin benzoate (134.24 q ha-1) and chlorpyriphos (125.43 q ha-1). Among bio-pesticides, highest mean marketable yield was recorded in Bacillus thuringiensis treated plots (114.45 q ha-1) followed by azadirachtin (101.11 q ha-1).

A study was conducted from January to June 2019 in Dhading district to identify the effective commercial insecticide against fruit and shoot borer of brinjal (Leucinodes orbonalis). A field experiment was conducted in Randomized Completely Block Design with five treatments (T1: Spinosad @ 1 ml/ 3 liters, T2: Chlorantraniliprole 1 ml/ 3 liters, T3: Cypermethrin 3 ml/ 1 liter, T4: Neem 3 ml/ 1 liter and T5: Control) and four replications. Result indicated that the fruit infestation percent and shoot damage reduction percent, fruit infestation reduction percent were highly significant with the application of insecticides. The shoot damage percent and fruit damage percent was the lowest with spinosad followed by chlorantraniliprole, cypermethrin and Neem. Thus, spinosad is the most effective insecticides for the management of fruit and shoot borer of brinjal in field conditions.
The present investigation was conducted during July to December 2014 at Central Research Farm, SHIATS, Naini, Allahabad. Three applications of seven insecticides viz; flubendiamide 39.35 SC (0.01%), chlorantraniliprole 20 SC (0.006%), cypermethrin 25 EC (0.006%), Spinosad 45 SC (0.01%), indoxacarb 14.5 SC (0.01%), fipronil 5 SC (0.005%) and imidacloprid 17.8 SL (0.004%) were evaluated against shoot and fruit borer, Leucinodes orbonalis. Minimum per cent of shoot infestation, fruit infestation and B:C ratio were recorded in chlorantraniliprole with (2.98%, 3.266% and 1:5.48) followed by flubendiamide (3.06%, 3.560% and 1:4.91) < spinosad (4.59%, 4.103% and 1:.4.65) < indoxacarb (4.80%,4.266%, and 1:4.44) < cypermethrin (5.97%, 4.870%, and 1:4.24) fipronil (8.61%, 6.44% and 1:3.66) < imidacloprid (8.63%, 6.73% and 1:3.39) < untreated control (water spray) (11.616%, 11.59% and 1:2.25) respectively.
Eggplant fruit and shoot borer (EFSB), Leucinodes orbonalis Guenee (Lepidoptera: Pyralidae ) is a key insect pest of eggplant in all eggplant growing areas of Nepal. A field experiment was carried out in Khumaltar, Lalitpur during summer season of 2014 using eight treatments as, i) Abamectin 1.9 EC @ 1.5 ml/lit; ii) Spinosad 45 SL @ 0.25 ml/lit ; iii) Emamectin Benzoate 5 SG @ 0.3 gm/lit; iv) Tozen @ 0.33 ml/lit; v) Karanjin 2 EC @ 2ml/lit; vi) Borer Gourd ( Bacillus thuringiensis var. Kurstaki 10 8 CFU/ml + Beauveria bassiana 10 8 CFU/ml + Verticillium lecanii 10 8 CFU/ml + Metarhizium anisopliae 10 8 CFU/ml) @ 2 ml/lit; vii) Chlorantraniliprole 18.5 EC @ 0.25 ml/lit and viii) Untreated check to test efficacy of newer bio - rational insecticides against L. orbonalis . The treatments were arranged in randomized complete block design (RCBD) with three re plications. The result showed that the fruit infestation percent on number and weight basis was significantly the lowest in Chlorantraniliprole (6.57 and 6.31) and Spinosad (12.08 and 11.15) treated plots as compared to other treatments. The Chlo rantranili prole treated plot recorded the maximum marketable yield (32.03 mt/ha) followed by Spinosad (30.93 mt/ha) with 34.39 percent and 29.77 percent increase in marketable fruit yield over untreated check, respectively. Hence, the use of Chlorantraniliprole and Spinosad cou l d be one of the better options for effective management of L. orbonalis.

There are 26 insect-pests species and few non insect-pests species infesting brinjal of which the shoot and fruit borer, Leucinodes orbonalis (Guen.); Budworms, Scrobipalpa blasigona; whitefly, Bemisia tabaci (Genn.); leafhopper, Amarasca devastans (Distant); jassid, A. biguttula biguttula (Ishida) are major one. The brinjal shoot and fruit borer is considered the main constraint as it damages the crop throughout the year. The yield loss due to the pest is to the extent of 70-92 per cent. Among the various insecticides evaluated against brinjal shoot and fruit borer (L. orbonalis), Emamectin benzoate 5 SG @ 12.5g a.i./ha treated plots showed lowest infestation and gave higher fruit yield (253.12) followed by Flubendiamide 480 SC (249.33) and Novaluron 10 EC (243.63). The boipesticią·¬ NSKE 5% most effective followed by Bacillus thuringensis, Verticellium lecanii and Beauveria bassiana. The highest cost: benefit ratio was obtained from NSKE 5% (1:24.40) followed by Indoxacarb 14.5 SC (1:24.13) and Emamectin benzoate 5 SG (1:24.03) which were also economical than other treatments.

During Kharif 2022, an experiment was carried out in the brinjal field (Cultivar- Makra) at the Central Research Farm of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, to investigate the field efficiency of several pesticides against the brinjal shoot and fruit borer. Nine treatments (including control) i.e., Diflubenzuron+Deltamethrin 20% WP + 2% SC @ 2.25 ml/3L, Spinosad 45 SC @ 0.1ml/3L, Indoxacarb 14.5 SC @ 0.3 ml/3L, Diflubenzuron 25% WP @ 2.4 ml/3L, Deltamethrin 2.8% EC @ 2.13 ml/3L, Cypermethrin+Quinalphos 3%+20% EC @ 3.6 ml/3L, Deltamethrin+Triazophos 1% WP+35% EC @ 7.5 ml/3L, Emamectin Benzoate 5 SG @ 0.20 ml/3L were imposed with three replications in RBD. All the insecticidal treatments were significantly superior to the untreated control. Spinosad 45 SC was discovered to be the best-performing pesticide treatment against shoot and fruit borer with the lowest percentage of fruit loss (10.04%). Deltamethrin 2.8% EC was the poorest effective treatment when compared to the other treatments because it generated the highest fruit destruction (13.88%). In terms of yield Spinosad 45 SC performed well than all other treatments (227.05 q/ha) and Deltamethrin 2.8% EC was the lowest (176.10 q/ha).

Minimum percent of shoot infestation, percent fruit infestation and B:C ratio were observed in cypermethrin 25 EC with (5.980%, 6.280% and 1:5.25) respectively. Which were followed by Neem oil (6.306%, 6.556% and 1:4.78) < NSKE (6.580%, 7.253% and 1:4.46) < Pongamia oil (7.346%, 7.273%, and 1:3.79) < Iluppai oil (7.656%, 7.793%, and 1:3.68) Garlic bulb extract (8.056%, 8.240% and 1:3.49) < Tobacco leaf extract (8.646%, 8.520% and 1:3.10) <untreated control(water spray) (11.756%,14.923% and 1:2.25) respectively.
The study was conducted at the Department of Entomology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November, 2012 to May, 2013 to eco-friendly management of brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guenee using some selected botanicals and chemical insecticides. Eight treatments were applied started with 28 days after transplanting of seedlings and repeated at 7 days interval and continued upto last harvest of the fruits. The treatments were T1= spraying of neem oil @ 3ml/litre of water, T2= spraying of neem seed kernelextract @ 100g/litre of water, T3=spraying of neem leaf extract @ 200g/litre of water, T4=spraying of garlic extract @ 2g/L of water, T5=spraying of Ripcord 10 EC @ 1ml/litre of water, T6=spraying of Suntap 50 SP @ 2ml/litre of water, T7=hand picking and destruction of infested shoots and fruits and T8=untreated control. Results found that the lowest shoot infestation (6.80%), lowest fruit infestation by number (13.67%) and weight (11.50%), maximum fruit yield (23.95 t/ha) were achieved by Ripcord 10EC @ 1ml/L of water (T5) compared to all other treatments. The highest percent reduction of shoot infestation (72.96%), the highest percent reduction of fruit infestation by number and weight (72.58% and 69.70% respectively), percent increase of yield (147.85%) over control were also achieved by Ripcord 10EC (Cypermethin 10 EC) @ 1ml/L of water. Thus it is revealed that among the treatments T5(Ripcord 10EC @ 1ml/L of water showed the best performance for controlling brinjal shoot and fruit borer followed bySuntap 50 SP (Cartap 50 SP) and Neem oil. Among botanical based treatments, neem oil performed as the best treatment in reducing the highest infestation (48.21% for shoot and 49.21% for fruit) caused by brinjal shoot and fruit borer.
