Management of Brinjal Shoot and Fruit Borer, Leucinodes orbonalis Guenee, with Selected Insecticides
Brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guenee is a serious insect pest of brinjal (Solanum melongena L.) in all brinjal growing countries. It is the most important pest in Asia, including Pakistan. Different insecticides were evaluated for the control of BSFB in a field study at Sahiwal, Pakistan during spring and fall sowing seasons. The study was carried out using Nirala variety of brinjal. Transplanting of nursery was done in the field on March 11 and August 15, 2012 for spring and fall seasons crop, respectively. The experiment was laid out in a Randomized Complete Block Design having four replications. Each plot had four rows at 50.0 cm spacing and plant to plant spacing was 30.0 cm. Insecticides used were spinosad (Tracer 240SC), flubendiamide (Belt 48 SC), emamectin benzoate (Timer 1.9EC), bifenthrin (Talstar 10EC), spinetoram (Delegate 25WG) and chlorantraneiliprole (Coragen 20SC). Insecticides were sprayed on April 2, 17 and May 2 for spring sown crop and on September 3, 18 and October 4 for fall sown crop. All infested fruits were picked from plots one day before insecticide application. Infected shoots were marked by tying a ribbon to all drooping shoots one day before spray. Fruit and shoot infestations were recorded seven and 14 days after insecticide application from plants in the middle two rows of each plot. All treatments reduced shoot and fruit infestation significantly as compared to the control. However, flubendiamide (Belt 48SC) and emamectin benzoate (Timer 1.9EC) treated plots had the least shoot infestation. For control of the borer in fruits, spinosad (Tracer 240SC) proved to be the most effective insecticide.
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.
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.
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.
Field experiments were conducted during Kharif-2009 and 2010 to evaluate the efficacy of new generation insecticides against brinjal fruit and shoot borer, Leucinodes orbonalis (Guenee). The new generation insecticides used in this study included Chlorantraniliprole 18.50% SC (Coragen), Flubendamide 39.35% SC (Fame), Indoxacarb 14.50% SC (Avaunt), Chlorfenapyr 10% SC (Intrepid) and Spinosad 45% SC (Spintor). Observations on shoot damage and fruit damage were recorded at regular intervals and insecticide sprays were done based on economic threshold level. The lowest fruit damage was recorded in the plots sprayed with Coragen in 2009 and 2010. Chlorantraniliprole 18.50% SC and Flubendamide 39.35% SC proved their superiority over other insecticides in reducing infestation of L. orbonalis and resulted in higher yields.

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.

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.
