An experiment was carried out to evaluate the efficacy of integrated management practices over farmers’ practices against insect pest complex of green gram (Vigna radiata L. Wilczek) during kharif season in the ‘A-B’ Block Farm of Bidhan Chandra Krishi Viswavidyalaya in 2019. The results revealed that the incidence of all of the insect pests viz. whitefly, pulse aphid, jassid, flower thrips, gram pod borer, spotted pod borer, blue butterfly, plant bug and pod bug was recorded comparatively less in Integrated Pest Management (IPM) plot as compared to farmers’ practices. The seed yield of green gram was also recorded a higher (1382.22 kg ha-1) in plots treated with integrated approaches as compared to farmer’s practices (476.94 kg ha-1). IPM module recorded maximum cost benefit ratio along with higher gross return and net profit as against farmers’ practices.

Efficacy and profitability of different management packages comprising white sticky trap, biopesticide and synthetic insecticides were evaluated against flower thrips and pod borers of mungbean at Pulses Research Center, Ishurdi, Pabna, Bangladesh during two consecutive seasons of kharif-1, 2015 & 2016. All the treatments significantly reduced flower infestation by thrips and pod borer infestation. The highest percentage of flower infestation and thrips population reduction was observed in installing white sticky trap + spraying of chlorfenapyr (Intrepid 10 SC) + spraying with emamectin benzoate (Proclaim 5 SG) followed by farmers practice, i.e. spraying imidacloprid (Imitaf 20 SL). Again, the highest pod borer infestation reduction was found in installing white sticky trap + spraying azadirachtin (Bio-neem plus 1EC) + spraying with spinosad (Success 2.5 SC) treated plots followed by installing white sticky trap + spraying chlorfenapyr (Intrepid 10 SC) + spraying with emamectin benzoate (Proclaim 5 SG). The highest grain yield was obtained from installing white sticky trap + spraying chlorfenapyr (Intrepid 10 SC) + spraying with emamectin benzoate (Proclaim 5 SG), but the highest return came from farmers practice (spraying Imidacloprid). This might be due to the higher cost of Intrepid 10 SC and Proclaim 5 SG reduced the return as well as benefit. Therefore, considering the efficacy and benefit, it is seen that the evaluated IPM package could not be profitable against low level infestation of flower thrips and pod borer infestation. It could be profitable that areas where serious out break of flower thrips and pod borer occurs.Jahangirnagar University J. Biol. Sci. 7(1): 55-64, 2018 (June)

Efficacy and profitability of insecticidal management practices using different insecticides were tested against insect pests of mungbean at Pulses Research Center, Ishurdi, Pabna, Bangladesh during two consecutive seasons of kharif-1 2013 and 2014. Insect infestations were reduced significantly by the application of synthetic insecticides. Spraying of Imidachloprid (Imitaf 20 SL) @ 0.5 ml/l of water showed the best efficacy in reducing flower infestation and thrips population followed by Fipronil (Regent 50 SC). Spraying of Thiamethoxam + Chlorantraneliprol (Voliam flexi 300 SC) @ 0.5 ml/l of water showed the best efficacy in reducing pod borer and flea beetle infestations. Spraying of Fipronil (Regent 50 SC) performed highest efficacy against stemfly infestation. The yield and the highest net return were obtained from Voliam flexi 300 SC, the highest benefit was obtained from Regent 50 SC treated plots. This might be due to the higher cost of Voliam flexi that reduced the profit margin and showed the lower marginal benefit cost ratio (MBCR) compared to Regent. Therefore, considering the efficacy and benefit, spraying of Fipronil (Regent 50 SC) @ 0.5 ml/l is the most profitable insecticidal management approach against insect pests of mungbean followed by Imidachloprid (Imitaf 20 SL) at the same dose.Bangladesh J.

Surveys were carried out in five local government areas of Ogbomoso Agricultural Zone Nigeria during planting season in 2010 to investigate rural farmers perceptions and management practices of insect pests of fruit vegetables. The survey involved 150 randomly selected farmers who were interviewed using structured questionnaire. Fruit vegetables planted by the farmers were okra, tomatoes, pepper and garden egg. Reasons given by farmers for cultivating fruit vegetables were significantly favored by age category, educational qualification, and secondary occupation of farmers (x2 = 4.757, P = 0.029). Field insect pests were perceived as the major production constraint to fruit vegetables in this zone. Majority of the farmer estimated 78.4 % rated insect pest as the most serious pest infesting fruit vegetables, the insect pests were grasshopper (Orthoptera), beetles (Coleoptera) and caterpillar (Lepidoptera). Integrated pest management module consisted basically of chemical and cultural control strategies, with weeding, shifting cultivation and crop rotation as main cultural control methods. More than 76.7 % of the farmers make use of cultural control because of unavailability and cost of chemical insecticides. Only 23.3 % had access to chemical insecticides in controlling insect pest of fruit vegetables.

Survey were undertaken in five zones of Oromiya and Amhara regional states, Ethiopia from February to March 2018 to investigate farmers’ status, knowledge, major chickpea production constraints and insect pest management practices of chickpea. The survey involved 293 randomly taken farmers, who are interviewed using a semi-structured questionnaire. Chickpea insect pests were considered as the main, among production constraints of chickpea by most of the interviewed farmers in Ethiopia. The majority of the farmers’ responded that Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is the most prevalent insect pests of chickpea under field condition and Callosobruchus chinensis (L.) (Coleoptera: Bruchidae) in storage. Development Agents (DAs) were the top pest advisory service providers in the current study. A conventional insecticide (namely; Lambda-cyhalotrin and Dimethoate) for the control of H. armigera was the most commonly used pest management methods. Moreover, Two times insecticide applications per cropping season were the most frequent, deployed by most of the interviewed farmers followed by cultural pest management practices. Use of biological control and resistant chickpea varieties against major insect pests were low to negligible in the current survey study in the area. The majority of the farmers began control decision when H. armigera larval stages were smaller and they did not consider larval number per chickpea plant for the decision. These results will be used to formulate future effective and sustainable integrated pest management (IPM) in chickpea for Ethiopian farmers emphasizing ecologically and economically-based approaches.

The experiments were conducted to develop insecticide (Imidachlorpid, Imitaf 20SL at 0.5 ml/l) application schedule for the effective management of thrips and pod borer attacking mungbean during kharif-I season of 2010 and 2011. In both the years, suppression of thrips population and pod borer infestation were higher in double sprayed treatment than single spraying. Single spraying at 35 DAS (100% flowering) and 42 DAS (100% podding stage) suppressed flower infestation by thrips upto 86 and 93%, respectively, during 2010 and 100 & 96%, respectively, during 2011. Double spraying at 42 DAS (100% podding) and 49 DAS (seed developing stage) reduced more pod borer infestation as much as 81-83%. In kharif-I 2010, significantly the highest yield (1798 kg/ha) and MBCR (4.67) were obtained from the plots sprayed twice with Imidachlorpid at 42 DAS (100% podding) and 49 DAS (seed developing stage) but in kharif-I 2011, significantly the highest yield (1457 kg/ha) and MBCR (5.75) were obtained from the plots sprayed twice with Imidachlorpid at 35 DAS (100% flowering) and 42 DAS (100% podding stage). The double spray schedule appeared to be more effective than single spraying against pod borer. But single spray at 42 DAS (100% podding stage) appeared as more effective against flower thrips.

Tomato is a highly cultivated vegetable in Tanzania. The intensive tomato cultivation and production in Tanzania has resulted in high pests and diseases build-up. A survey to identify and quantify entomofauna diversity in different seasons and pest management practices in Meru District was conducted. In addition, a laboratory experiment was done to assess the effectiveness of commonly used pesticides SnowBecco (Thiamethoxam)and Belt (Flubendiamide) against two dominating insect pests, white flies (Bemisia tabaci (Gennadius, 1889)) and leaf miner (Tuta absoluta (Meyrick, 1917)), respectively. The results obtained revealed that, tomato fields in Meru District had significantly higher entomofauna build up during dry season than the rainy season (U0.05 (df, 24)= 45, p = 0.0441). More than 70% of all collected entomofauna were dominated by the whiteflies (Bemisia tabaci) and tomato leaf miners (Tuta absoluta) belonging to orders Hemiptera and Lepidoptera, respectively. It was also observed that, the common pesticides management practices were the use of pesticidal cocktail, broad spectrum insecticides, use of botanical pesticides, frequent application of pesticide and insecticides over dosage. Moreover, yield reduction due to whiteflies and tomato leaf miners infestation were observed in terms of reduced fruits number per plant (38 and 18.4%), fruit size (22.4 and 14.2%), and fruits weight per plant by 43.6 and 26.2%, for Bemisia tabaci and Tuta absoluta, respectively. The study showed that the recommended doses in both tested insecticides caused significant pest mortality (F0.05 (df, 19) = 4.367, p = 0.0199) and (F0.05(df, 19) = 4.761, p = 0.0147) for B. tabaci and T. absoluta, respectively, within a specified period of time. The results suggest that high insect pest infestations could be caused by factors other than development of insecticidal tolerance including inappropriate identification of insect pests due to lack of training, and inappropriate selection and application of insecticides. Consequently, frequent application of broad spectra insecticides not only increases production expenses but also disrupts agroecosystem by killing beneficial entomofauna and disrupting soil organisms that are susceptible to insecticide toxicity.

Direct damage due to insect pests is one of the major causes limiting the yield potential of blackgram (Vigna mungo L. Hepper) in Nepal. A total of 17 blackgram genotypes were screened for resistance to major insect pests, including aphid (Aphis craccivora Koch.), whitefly (Bemisia tabaci Genn.), hairy caterpillar (Spilosoma obliqua Walker) and pod borer (Helicoverpa armigera Hubner) in National Maize Research Program, Rampur, Chitwan during summer season of 2018 and 2019. The design of the experiment was randomized complete block having three replications. Genotypes were sown on first week of August in a unit plot size of 4 rows of 2 m long with 40 cm row to row spacing and continue plant to plant spacing was maintained and net harvested plot was 3.2 square meters. The recommended dose of fertilizer was 20:40:20 N:P2O5:K2O kg/ha and seed rate 25 kg/ha. The package of agronomic practices was followed as per national recommendation. Data on insects were collected by counting the number of insects per plant. The yield and yield components were recorded at harvest. All screened genotypes differed significantly (p<0.05) for insect population, yield and yield components. From two years field data, three genotypes BLG0069-1, BLG0036-1 and BLG0079-1 had lower number of above mentioned insect populations, exhibited more resistant in both years and produced higher grain yield (~1.5 t/ha) than other genotypes. These genotypes might be useful for the development of major insect pest tolerant high yielding blackgram variety in subtropical region of Nepal.
