Appraisal of resistant genotypes against brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis, Guenee

The main purpose of this study was to find out the best variety of brinjal having resistance to BSFB. A pot experiment was carried out at the germplasm centre, Agrotechnology Discipline, Khulna University, Khulna during February 2014 to August 2014. The experiment was laid out in CRD using thirteen varieties with five replications. The varieties were V1=BARI begun-1, V2=BARI begun-4, V3=BARI begun-5, V4=BARI begun-6, V5=BARI begun-7, V6=BARI begun-8, V7=BARI begun-9, V8=BARI begun-10, V9=Makra, V10=Muktokashi, V11=Lalita, V12=Hazra, V13=Chaga. Data were collected on total number of shoot, total number of infested shoot, percentage of shoot damage, percentage of shoot infestation reduction, numbers of larvae per infested shoot, total number of fruit, percentage of fruit damage, percentage of fruit infestation reduction, numbers of larvae per infested fruit. Results have shown that the minimum shoot infestation was found in BARI begun-6 (29.60%, 32.40%, 29.86% and 29.38%, respectively at four different stages of eggplant). Percent of fruit infestation was minimum in V4 (BARI begun-6) (25.16%, 27.42% and 25.40% at three stages respectively).J. Bangladesh Agril. Univ. 16(2): 227-231, August 2018

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.

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 study on biochemical basis of resistance against Leucinodes orbonalis infestation was conducted during the year 2011-2012. The results revealed that highest chlorophyll-‘a’- content of 0.497 mg/gfw was recorded in the susceptible genotype SHB-1.The lowest amount of 0.319 and 0.381 mg/gfw was observed in the resistant genotypes Brinjal-85 and Local long respectively, which were significantly different from other evaluated genotypes. The chlorophyll ‘a’content was positively correlated with the brinjal shoot and fruit borer infestation. Thehighest chlorophyll -‘b’- content of 0.442 mg/gfw was recorded at 70 DAT (days after transplanting). The amount of chlorophyll -‘b’- varied significantly among the genotypes at different ages and decreased with the age of crop. The average highest amount of chlorophyll -‘b’- was estimated in the genotype SBH-1 which was significantly at par with hybrid SBH-2. The lowest chlorophyll -‘b’- content was recorded at 40 DAT in the genotype Brinjal-85 followed by Local Long. The lowest amount of total chlorophyll was estimated in the resistant variety as compared to susceptible therefore exhibiting lowest level of infestation.

The field experiments were carried out in the farmer field at C. Mutlur near Chidambaram during rabi and kharif 2017. The results of experiments revealed that the per cent shoot damage and fruit damage by E. vittella on bhendi reached peak on 13th and 15th MSW in rabi season, whereas 43rd and 42nd MSW in kharif season. The per cent shoot damage and fruit damage by E. vittella were exerted significantly positively correlated with minimum (0.552 & 0.698) and maximum temperature (0.629 & 0.748), whereas rainfall positively correlated with per cent shoot and fruit damage but it was non significant (0.111 & 0.297), however relative humidity (-0.178 & -0.210) and sunshine hours were exerted negatively correlated with per cent shoot damage and fruit damage by E. vittella during rabi 2017. The kharif season 2017 indicated that per cent shoot damage and fruit damage of bhendi was positively non significant association with RH and rain fall, while negatively non significant correlation with minimum temperature (-0.43 & -0.309) and sunshine hours (-0.265 & -0.283) was recorded.

The Cost

ABSTRACT: The experiment was conducted in randomized block design with 7 treatments and 4 replications, to evaluate the performance of some botanical products against the pest complex of brinjal.The treatments included Triazophos 40E.C. 0.04%,Neem oil 1 %,Achook 5 %,NSKE 5%, Karanj oil 1%,Eucalyptus oil 1% and an untreated control. Four spraying of each treatment were conducted starting 30 days after transplanting, at an interval of 15 days. Observation on shoot and fruit damage by Leucinodes orbonalis were recorded. The results revealed that Triazophos 40E.C. 0.04%,was significantely superior over all the botanical treatments shoot damage in different treatments & ranged between 3.9 to 10.1%.Highest healthy fruits yield (24.76q/ha) was recorded in the treatment of Triazophos 40E.C. 0.04% followed by the treatment of neem oil 1% (20.54 q/ha healthy fruits), and both the treatments were statistically at par Yields in remaining treatments were at par and ranged between 19.57 and 15.23 q/ha. Lowest yield (10.50 q/ha in healthy fruits) was registered in untreated control.Highest cost benefit ratio of 1:6. 31 was treatment of Triazophos 40 EC 0.04%. Application of neem oil 1% registered the cost benefit ratio of 1:1.79 and was found most economical.
