Context: Female pheromone attracts the male eggplant shoot and fruit borer. The pheromone lure could be used in catching male adults to control this pest population in eggplant fields.Objectives: To study the efficacy of sex pheromone (lure) on the male moth catch of eggplant shoot and fruit borer (ESFB) Leucinodes orbonalis Guenée, shoot and fruit destruction and fruit yield in the control, IPM operated fields and farmer’s fields.   Materials and Methods: For pheromone trap operation the experiments were done in four sites of the Rajshahi City. For IPM strategy two sites were selected in Paba upozilla. Pheromone traps were operated with the lure combination of 100:1 of E11-16: Ac and E11-16: OH. The trap consisted of a 3-liter capacity, 22-cm tall rectangular or round clear plastic container. A triangular hole is cut in any two opposite sides starting 3 to 4 cm from the bottom. The traps were randomly assigned in the study plots and installed with the help of bamboo stick. Sex pheromone trap height from ground level in the field was standardization for best trapping efficiency. For this traps were placed at 0.5 m and 1 m high above the ground in the field. In both cases control fields (without insecticide) of the same size were used in the experiments.   Results: The number of ESFB males in ten trap catches were 1.7 to 4.5 with a mean number of 3.26 ± 0.32, 8.49 ± 0.36, 5.20 ± 0.24 and 14.95 ± 0.34 catch/trap in the Fields 1,2,3 and 4 respectively. The average moth catch per trap was 1.76 ± 0.56 and 4.54 ± 0.94 in the 0.5 and 1 m lure respectively. The damaged shoot was 19.34 ± 2.31% at 0.5 m lure height, whereas at 1m height no damaged shoot was recorded. A damaged fruit was recorded as 29.74 ±1.87% and 14.47 ± 2.29% with the fruit yield in q/ha was 176.58 ± 6.38% and 232.56 ± 6.63% at the 0.5 and 1m lure height plots respectively. When no trap was operated in the eggplant fields the shoot damage, fruit damage and fruit yield were 3.48%, 31.15% and 13.70 kg/100m2 respectively in the non-IPM blocks. On the otherhand they were 1.56%, 10.66% and 27.54 kg/100m2 in the IPM blocks respectively.   Conclusion: The sex pheromones which have been extensively studied and already are in management programmes should be fine tuned to improve their efficacy in totality in an Integrated Pest Management Programme on the basis of feedback from the extension workers, and farmers.   Key words: pheromone; Eggplant; Leucinodes orbonalis; IPM DOI: http://dx.doi.org/10.3329/jbs.v18i0.8768 JBS 2010; 18(0): 10-15

Fruit Borer

Brinjal Shoot and Fruit Borer, Leucinodes orbonalis , is a major constraint in brinjal production. Investigation was taken up to understand the mating status of L. orbonalis male adults caught in sex pheromone trap. The genetalia of the male moths were examined for the presence of sperm cells and sperm bundles. The results indicated that 55.38 per cent of males caught in the trap were unmated whereas 26.15 per cent of them are partially mated and 18.40 per cent males are spent ones. The study indicated presence of L orbonalis male moths of different mating status in the pheromone catches.

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
