A field experiment was conducted in the farmer’s field at Salaipur, Mithapukur, On Farm Research Division, Rangpur during 2015-2016to control cucurbit fruit fly effectively through the use of sex pheromone trap. The trial was conducted among six farmers. Three treatments viz., T1 (Sex pheromone + Poison bait + Sanitation (9 spot)), T2 (Sex pheromone + Poison bait + Sanitation (16 spot)) and T3 (Farmers practice) were compared.  The total land area was 7200m2. The higher fruit yield (63.99t/ha) was obtained from T2 (Sex pheromone + Poison bait + Sanitation (16 spot). The lower fruit yield (27.99 t/ha) was obtained from T3. The gross margin (Tk. 294706/ha) and gross return was also higher with the use of T2 (Sex pheromone + Poison bait + Sanitation (16 spot).The highest gross margin and gross return was found in T2 (Sex pheromone + Poison bait + Sanitation (16 spot) treatment. Use of insect lures can improve safe vegetable production as well as yield. Innovative agricultural technologies have the potential to increase yield and income of smallholder vegetable farmers in the northern region of Bangladesh.

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

Field and laboratory studies were carried out to find out the extent of fruit fly infestation at different fruiting stages of bitter gourd as well as to determine the efficacy of some pesticidal and other control approaches applied either separately or in combination. The pesticidal efficacy of three commonly used insecticides such as secufon, malathion, karate and karanja oil as botanicals with the concentrations of 0.25%, 0.50%, 0.75% and 1.00% respectively was determined against the larvae of cucurbit fruit fly, Bactrocera cucurbitae in the laboratory based on mortality at different time intervals. All the pesticides caused maximum mortality at 72 h with 1.00% concentration. The level of fruit fly infestation at different fruiting stages of bitter gourd ranged from 8.91% to 88.19%, 9.24% to 94.89% and 5.01% to 89.27% at early, mid and late fruiting stage, respectively. Soil treatment with furadan @ 10kgha-1 + bagging of fruits showed significantly lowest infestation (9.46%) which was ten times lower than that of untreated control (91.43%). The other control approaches viz., sex pheromone, bait trap with secufon + cucurbit chop, bait trap consisted of secufon + banana chop reduced fruit fly infestation to a significant level. The highest number (83.67) of flies trapped at mid fruiting stage of bitter gourd was recorded in sex pheromone trap while the ratio of male and female flies ranged from 1.13 to 1.24 in the trapped individuals.Bangladesh J.

AbstractThe synthetic sex pheromone (dicastalure) of the red bollworm of cotton, Diparopsis castanea Hmps., in Central and Southern Africa, and an inhibitor of male sexual attraction (trans-9-dodecenyl acetate,=IIA), were used in an enclosed 0·2 ha cotton field-cage to reduce successful female matings. Over one month dicastalure at 21·0 and 42·3 g/ha produced average reductions in mating of 47·9% and 72·5% respectively and 37·9 g IIA/ha produced an overall reduction in mating of 71·5%, or 79·5% in released moth populations, over the same period. The proportion of virgin females present in disruption situations was significantly greater than in untreated populations and was density-independent for moth populations of up to 2 200/ha. The proportion of fertile eggs in disruption situations was correspondingly reduced to 30·2% from an average of 67·9% in control cycles. Reduction in sex pheromone trap catches is an unsatisfactory indicator of the extent to which males are prevented from inseminating females and considerably over-estimates the true degree of disruption. This is the first time that a naturally occurring inhibitor has been used successfully to disrupt mating in a field population of insects and it indicates the potential of the method for the control of high density pest populations in cotton. However, use of polyethylene dispensing mechanisms similar to those used in the field-cage disruption experiments would be unsuitable as a practical method of dispensing behaviour modifying chemicals and it is suggested that, for suitably controlled release of such chemicals, currently available microencapsulation technology offers the best prospects.

Government determination to eradicate extreme poverty and food insecurity among Batswana through small scale vegetable production program appears not to transform their economic stance. Rural households that are part of Poverty Eradication Programme were investigated to determine if backyard gardens were profitable enough to improve incomes, reduce extreme poverty, and increase food security. The study aimed at analysing profitability and identifying factors that affect profitability of backyard gardening. Multi-stage sampling technique was used to collect data from 100 rural households who are part of the backyard garden scheme. Data was analysed using descriptive statistics, gross margin analysis and regression analysis. Results indicated that backyard gardening was a viable activity though profitability was affected by amount of fertilizer applied, market availability and area planted. Beneficiaries indicated that the production and marketing constraints they faced included pests and diseases, lack of water, lack of market and poor prices. Program leaders must recognize the production and marketing constraints themselves as well as plan for the possibility that continual financial support for investment in the initial years of operation.

Raised bed production trials were conducted to evaluate the effectiveness of effluent from a biofloc-style recirculating aquaculture system producing nile tilapia (Oreochromis niloticus) as nutrient-rich irrigation water for fall ‘Celebrity’ tomato (Solanum lycopersicum) production. The objective of this study was to provide baseline vegetable production data and justification for using aquaculture effluent as a water and nutrient resource. The experiment was a split-plot, randomized block design with three treatments: aquaculture effluent, granular fertilizer, and fertigation. Tomato seeds were sown in June, transplanted in August, and grown until Oct. 2019 in nine replicated raised beds. Conventional field tomato production practices were followed throughout the trial, and data were collected for tomato fruit yield, market quality, size, leaf greenness (SPAD), and foliar nutrient analysis. Fruit yield was similar between fertigated and aquaculture effluent treatments, with granular fertilizer resulting in yield that was significantly lower (P ≤ 0.033). SPAD measurements were similar among treatments. All nutrients met or exceeded sufficiency ranges. Foliar nutrient analysis revealed no significant difference for nitrogen, phosphorus, potassium, magnesium, calcium, boron, zinc, manganese, and iron among treatments. Sulfur and copper levels were significantly lower (P < 0.05) with aquaculture effluent treatment as compared with the granular and fertigated treatments. Overall, tomato production using aquaculture effluent as a water and nutrient supplement produced similar yields to commercial practices, making it potentially viable for producers.
