AbstractThe status of insecticide resistance in field populations of eggplant fruit and shoot borer, Leucinodes orbonalis (Guenée) (Lepidoptera: Crambidae) from the major vegetable growing regions of India was determined during the cropping seasons of 2009–2010 and 2010–2011. Six commonly used insecticides: carbaryl, chlorpyriphos, deltamethrin, endosulfan, fenvalerate, and profenofos were tested against L. orbonalis larvae. The resistance ratios (RR) at the lethal dosage (LD)50 levels were estimated as RR=LD50 field strain/LD50 susceptible strain. The L. orbonalis populations exhibited widespread resistance to tested insecticides. The highest average RR in the two-year study was observed in the assays of populations with deltamethrin (21.50–82.42-fold) followed by assays conducted with endosulfan (24.47–68.26-fold), chlorpyriphos (22.17–63.14-fold), carbaryl (39.18–49.09-fold), and fenvalerate (14.00–44.66-fold); and the lowest average RRs were observed in the assays with profenofos (16.65–39.43-fold). The high levels of LD50 values can be attributed to the long-term indiscriminate use of these insecticides in eggplant (Solanum melongena Linnaeus; Solanaceae) growing regions.

Eggplant (Solanum melongena Linn.), or brinjal, was engineered to express an insecticidal protein (Cry1Ac) from Bacillus thuringiensis (Bt) and commercialized in Bangladesh on a limited basis in 2014. As part of an insect resistance management strategy, studies were conducted to determine the susceptibility of the targeted insect pest, the eggplant fruit and shoot borer, Leucinodes orbonalis (Guenée), to Cry1Ac using a diet-incorporation bioassay method. Eighteen populations of L. orbonalis were collected from the main brinjal growing areas in 17 districts of Bangladesh during 2018–2019 and assayed. Larvae from each population were reared to adults and allowed to mate. Eggs from the matings were allowed to hatch, and neonates were used for bioassays. Bioassays were performed with different concentrations of Cry1Ac and an untreated control. Median lethal concentrations (LC50) ranged between 0.035 and 0.358 ppm and molt inhibitory concentration (MIC50) values ranged from 0.008 to 0.181 ppm. Variation in susceptibility among field populations was 10.22-fold for LC50 and 22.63-fold for MIC50. These results were compared to values from 73 populations in India. Overall, the results showed similar natural variation and suggest that these Bangladeshi values can be used as benchmarks for resistance monitoring as Bt brinjal becomes more widely adopted in Bangladesh.

Some commonly used varieties and hybrids of brinjal were evaluated against shoot and fruit borer, Leucinodes orbonalis Guenee during late kharif 2015-16 in insectary premises, Department of Entomology, S.V. Agricultural college, Tirupati. Eleven varieties and hybrids of brinjal were tested against shoot and fruit borer, Leucinodes orbonalis. The shoot damage was ranged from 4.06 to 15. 37 per cent in different cultivars. The lower shoot damage was recorded in Arka Neelakanth (4.06%), CVK (4.66%), Shyamala (5.30%), PHB-909 (6.06%) and Arka Keshav (6.46%). The mean fruit damage comparatively was less in hybrid Shyamala, Arka Neelakanth. In these two lines, on number basis, the mean per cent damaged fruits were 23 to 26 per cent. On weight basis also, similar results were obtained (22 to 23 % mean fruit damage). The highest mean fruit damage was recorded in CVK variety (65.83% on number basis and 59.55% on weight basis) followed by Ranjitha hybrid and Arka Kusumakar variety (58 to 59% and 53 to 57% on number and weight basis respectively) at 100 days after transplanting. In remaining lines also, above 35 per cent fruit damage was recorded. Plant height, number of branches, leaves and leaf area did not show any impact on the damage by L. orbonalis. Density of trichomes was found to have negative impact on L. orbonalis. The highest number of trichomes (201 per cm2 leaf area) was recorded on Shyamala. The lowest were in Arka Kusumakar which was highly susceptible one. However, in many of the tested lines, above 150 trichomes/cm2 leaf area were noted.

A field experiment was conducted to study the bioefficacy of some insecticides against Leucinodes orbonalis during kharif season of 2014 on brinjal var. BR-112 at Entomology Research Area of CCS Haryana Agricultural University, Hisar. Five foliar sprays of insecticides viz., cypermethrin 25EC @ 43.75 g a.i/ ha, fenvalerate 20EC @40 g a.i/ ha, deltamethrin 2.8EC @ 14 g a.i/ ha, chlorpyriphos 20EC @ 200 g a.i/ ha, Prempt 20EC @ 150 g a.i/ ha, malathion 50EC @ 250 g a.i/ ha and Nimbecidine 0.03% @ 3 ml/l were evaluated and it was found that all the insecticides proved significantly superior (at 5% level) to control (untreated) in reducing the damage of shoot and fruit borer in brinjal. Among all, deltamethrin proved most effective in reducing shoot damage (60.40%) and fruit damage, on number basis (88.87%) and weight basis (88.89%) over control. Deltamethrin recorded the highest marketable fruit yield of 132.27q/ha and lowest was found in case of Nimbecidine (33.53 q/ha). Highest (1:8.7) cost to benefit ratio was recorded in deltamethrin followed by fenvalerate (1:8.5), cypermethrin (1:6.5), chlorpyriphos (1:4.5), Prempt (1:1.9), malathion (1:0.6) and Nimbecidine (1: -0.3). From these findings, it was revealed that synthetic pyretheroids being the most effective and economic over other insecticides, may be incorporated in IPM practices followed against brinjal shoot and fruit borer.
