The pest also attacks sweet potato plants during the dry season (Indiati & Saleh, 2010), and this pest is harmful when in the field, even as a storage pest (Kalshoven, 1950). The weevil attacks cause a decrease in the quantity and quality of sweet potatoes. The most significant reduction in the rate of sweet potatoes occurs in larval and imago pest stages (Anitha, K., Anitha, G., Hirur, Suresh, Nayak, 2021). Symptoms of the damage caused are the formation of terpenoid compounds, which are compounds that cause a bitter taste so that the tubers cannot be consumed (Jansson &

Smith has the potential to reduce corn production, so its existence needs to be controlled. The aim of this research is to obtain control techniques that could reduce the intensity of S. frugiperda pest’s attack. The research was conducted from June to October 2020. The experiment was designed in a randomized block design (RBD) with 9 replications and 3 treatments consisting of non-control (NP), PHT-biointensive (BI), and synthetic pesticides. In BI treatment, neem leaf extract (25 mL/plot) and Beauveria bassiana (6,25 g/plot) were used. Meanwhile, the PS treatment used deltametrin active ingredient (3,125 mL/plot). The volume of spray used was 1,25 L. The results showed that PS control techniques gave the best results in suppressing the intensity of fall armyworm S. frugiperda attacks (0,57%-7,04%) followed by BI treatment (0%-6,89%) and NP (0,97%-8,29%).

The use biological agents such as entomopathogen may become an alternative in supporting integrated pest management. One of entomopathogenic fungus that has been used in controlling pests is Beauveria bassiana. However, a good alternative media for the growth of B. bassiana is required to produce more optimal conidia density and germination. This study was aimed to determine the effect of several media on the growth of B. bassiana and its conidial density. The method used in this study was compeletely randomized design with 5 replications. The experimental treatment consisted of PDA, maize, rice, and mungbean. The result showed that there was no significant differences among maize, mungbean, and PDA media in supporting the growth of B. bassiana, with the means of colonies diameter at 8.91 cm, 8.89 cm, and 9.00 cm, respectively. Moreover, the growth rate, conidia density, and v...

One of the common cultivation practices carried out by farmers was the control of pests by using pesticides. This study aimed to find out which pest management strategies that are effective in maintaining environmental health and understanding how natural enemies were affected by the application of synthetic pesticides. The first treatment was paddy field with integrated pest management (IPM), the second treatment was conventional rice field with a technique of chemical pest management (C-T), while the third treatment was mixed pest management (M-T). Insect sampling was conducted using sweep net, pitfall trap, and direct observation for 10 weeks after planting. Overall, it was found 100 morphospecies, 9 Orders, 56 families, with a total abundance of 6242 individuals per planting season. Based on functional roles it was found 39% as herbivores, 30% as predators, and 14% as parasitoids, 1% pollinators, and 13% decomposers. High insect diversity and abundance were found in the plots using low synthetic pesticides. The C-T control plot had a lower relative abundance of herbivorous insects, parasitoid insects, predators, and decomposers than the other control plots. H' and D index in the Integrated Pest Management (IPM) and Mixed Pest Management (M-T) plots did not show significant differences but differed significantly from the Chemical Control plot (C-T). Therefore, controlling the herbivore insects could apply the pest management based on IPM strategies.

Green bean media gave the best spore density results of 2.08×107. Whereas the germination capacity of the media ranged from 63.94% to 94.23%. Germination showed no signi...

Smith has the potential to reduce corn production, so its existence needs to be controlled. The aim of this research is to obtain control techniques that could reduce the intensity of S. frugiperda pest’s attack. The research was conducted from June to October 2020. The experiment was designed in a randomized block design (RBD) with 9 replications and 3 treatments consisting of non-control (NP), PHT-biointensive (BI), and synthetic pesticides. In BI treatment, neem leaf extract (25 mL/plot) and Beauveria bassiana (6,25 g/plot) were used. Meanwhile, the PS treatment used deltametrin active ingredient (3,125 mL/plot). The volume of spray used was 1,25 L. The results showed that PS control techniques gave the best results in suppressing the intensity of fall armyworm S. frugiperda attacks (0,57%-7,04%) followed by BI treatment (0%-6,89%) and NP (0,97%-8,29%). The highest pest populations overall were found in NP treatment and the lowe...

The use biological agents such as entomopathogen may become an alternative in supporting integrated pest management. One of entomopathogenic fungus that has been used in controlling pests is Beauveria bassiana. However, a good alternative media for the growth of B. bassiana is required to produce more optimal conidia density and germination. This study was aimed to determine the effect of several media on the growth of B. bassiana and its conidial density. The method used in this study was compeletely randomized design with 5 replications. The experimental treatment consisted of PDA, maize, rice, and mungbean. The result showed that there was no significant differences among maize, mungbean, and PDA media in supporting the growth of B. bassiana, with the means of colonies diameter at 8.91 cm, 8.89 cm, and 9.00 cm, respectively. Moreover, the growth rate, conidia density, and v...

One of the common cultivation practices carried out by farmers was the control of pests by using pesticides. This study aimed to find out which pest management strategies that are effective in maintaining environmental health and understanding how natural enemies were affected by the application of synthetic pesticides. The first treatment was paddy field with integrated pest management (IPM), the second treatment was conventional rice field with a technique of chemical pest management (C-T), while the third treatment was mixed pest management (M-T). Insect sampling was conducted using sweep net, pitfall trap, and direct observation for 10 weeks after planting. Overall, it was found 100 morphospecies, 9 Orders, 56 families, with a total abundance of 6242 individuals per planting season. Based on functional roles it was found 39% as herbivores, 30% as predators, and 14% as parasitoids, 1% pollinators, and 13% decomposers. High insect diversity and abundance were found in the plots using low synthetic pesticides. The C-T control plot had a lower relative abundance of herbivorous insects, parasitoid insects, predators, and decomposers than the other control plots. H' and D index in the Integrated Pest Management (IPM) and Mixed Pest Management (M-T) plots did not show significant differences but differed significantly from the Chemical Control plot (C-T). Therefore, controlling the herbivore insects could apply the pest management based on IPM strategies.
