An attempt was made to evaluate the efficacy of novel insecticides against brinjal fruit borer, Leucinodes orbonalis at Student Instructional Farm of C.S.A.U.A&T., Kanpur, during Rabi season 2015-16 on var. Type-3. Among the various treatments like imidacloprid 17.8 SL @ 1.0 ml/lit., indoxacarb 14.5 SC @1.0 ml/lit., profenofos 50 EC @ 2.0 ml/lit., spinosad 45 SC @ 0.4 ml/lit., thiamethoxam 25 WG @ 0.1 gm/lit., acephate 75 SP @ 0.7 gm/lit. and untreated control, among them imidacloprid 17.8 SL was found most effective in reducing the mean shoot infestation and fruit infestation followed by indoxacarb 14.5 SC, profenofos 50 EC, spinosad 45 SC, thiamethoxam 25% WG and acephate 75 SP.

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).

Brinjal is one of the important vegetable of world. It is smooth shiny skinned deep purple fruit and considered as staple vegetable. It accumulates vitamin A & D and minerals like calcium, phosphorus, potassium, sulphur, iron, iodine and copper. Brinjal shoot and fruit borer (Leucinodes orbonalis Guenee) is one of major chewing insect pest of brinjal and its infestation cause severe losses to this crop. In Pakistan farmers mostly rely on the chemicals to control pests. In the present study the efficacy of some new chemistry insecticides was evaluated against brinjal shoot and fruit borer. The experiment was conducted by using fruit dip method against 1st instar larvae. The results revealed that flubendamide was most effective insecticide among all the tested insecticide with 87% mortality after 72 h of application while imidacloprid was the least effective. The finding of this research provides useful information regarding better management of BFSB in the field.

The studied data of shoot and fruit borer shows that, results were statistically superior over control in suppression of shoot damage caused by shoot borer. Lowest shoot infestation was recorded in treatment spinosad 0.01% (12.13%). The other effective treatments in minimizing the percentage damage of shoot borer were listed in descending order as emamectin benzoate 0.002% (15.05%) > cypermethrin 0.005% (17.19%) > imidacloprid 0.025% (21.95%) I > Metarrhizium anisopliae 1 lit/ha (23.16%) > B. Bassiana 1 lit/ha (24.88%) > Azadirachtin 2.5 ml ml/lit (24.88%) > mechanical shoot clipping (27.10%) respectively, these treatments were found superior over control (water spray) recording highest shoot infestation (36.60%) and for the fruit borer The next effective treatments in minimizing the percentage of fruit borer are listed in descending order as emamectin benzoate 0.002% (16.57%) > cypermethrin 0.005% (18.70%) > imidacloprid 0.025% (22.06%) > Metarrhizium ani...

The present investigation was carried out during the Kharif season, 2017-18 at Student's Instructional Farm, N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P) to study the efficacy of bio-insecticides and botanicals against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee). The bio-insecticides and botanicals tested were: Emamectin benzoate 5 SG @ 75 g a.i/ha, Spinosad 45 SL @ 18 g a.i/ha, NSKE 5%, Karanj seed extract 5%, Onion extract 5%, Garlic extract 5%, Tobacco extract 5%, Cannabis (bhang) leaf extract 5%, Wood ash 10 g/ plant and compared with control. Results showed that Emamectin benzoate 5 SG (75 g a.i/ha) treated plots showed lowest infestation and gave higher fruit yield (313.85 q/ha) followed by Spinosad 45 SL (18 g a.i/ha) and NSKE (5%) which gave 300.58 and 284.33 q/ha fruit yield respectively. The least effective treatment was Wood ash (10 g/plant) and yielded only 225.14 q/ha healthy fruits. The maximum cost-benefit ratio was obtained from Emamectin benzoate 5 SG 75 g a.i/ha (1:21.23) treated plots. Tobacco leaf extract 5% treated plots though ecofriendly but gave least cost-benefit ratio (1:1.27). This study recommends the use of bioinsecticides and botanicals as they are significantly efficient in managing the brinjal shoot and fruit borer infestation.

Seven organic products and an insecticide- emamectin benzoate 5SG (0.002%) were evaluated against the brinjal shoot and fruit borer Leucinodes orbonalis (Guenee) at the research farm, Palampur. The results among the organic products, Agniastra (5%), Brahmastra (5%) and cow urine (10%) were effective. Emamectin benzoate was superior to the organic products giving maximum yield of fruits and marketable fruits (43.97 and 42.57 q/ ha, respectively).

It is extremely challenging to control the Leucinodes orbonalis Guenee, also known as the brinjal shoot and fruit borer (BSFB) in brinjal cultivation. Considering the prevailing dangerous effects of chemical pesticides on human health and ecology, biopesticides can be an effective weapon to sustain against BSFB. Among the different types of biopesticides, Spinosad was found to be more effective @0.4ml/L to recommend as it was elucidated the lowest shoot infestation (10.19%) and fruit infestation (25.53%) followed by Abamectin @1.2ml/L (12.82% and 30.71%). Furthermore, other biopesticides like Buprofezin, Abamectin, Neem oil, Mahogony oil, Neem leaf extract, and Garlic bulb extract are also used to finding out the best possible solution of existing threats from BSFB. Consequently, with the higher efficacy of Spinosad the economic point of view can be accentuated through the highest benefit-cost ratio (2.28) and quantity of marketable fruit yields (36.62 tons/ha) in the study area.
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.
