Abstract

Bamboo (Dendrocalamus asper Backer) is commonly used as structural material in the tobacco curing barns of PT Perkebunan Nusantara X, where it is installed in the ground as supporting pillars. However, subterranean termites (Coptotermes curvignathus Holmgren) pose a significant threat to bamboo, causing brittleness and structural damage. This study aimed to identify the most effective wood vinegar treatment to protect bamboo against termite attacks. This research conducted at February 2022 to July 2023 in Jember, East Java, Indonesia. This study used explanatory research methods. Tobacco stalk-derived wood vinegar was applied to bamboo using seven different treatments (labeled A to G), each replicated three times, and compared with untreated control bamboo. Wood vinegar made from tobacco stems is effective in suppressing subterranean termite attacks on bamboo. After 18 months of observation, treatment E—where bamboo was soaked in wood vinegar for one day, followed by the application of one liter of wood vinegar to the surrounding soil—proved to be the most effective. This treatment reduced termite damage by 29% compared to the control and minimized brittleness to only 12%, outperforming the other treatments. Consequently, treatment E is recommended for bamboo used in curing barns to enhance resistance against subterranean termite attacks.

Abstract

The silkworm is an insect with high economic value due to its ability to produce cocoons, which are processed into silk fibers. Samia cynthia ricini is a type of silkworm relatively new to Indonesia. This insect can utilize various plants as feed, with castor leaves as the primary host and cassava leaves as the secondary host. However, information regarding the impact of diet type and population density on biological parameters, such as survival rate, development time, cocoon weight, and fecundity, remains limited. This study aims to evaluate the effects of diet type (castor and cassava leaves) and population density (20, 30, 40, and 50 individuals per container) on the biology of S. c. ricini. The research used a factorial randomized complete block design (RCBD) with two factors. Results indicated that diet type and population density significantly influenced the biological parameters of S. c. ricini. Silkworms fed castor leaves exhibited higher survival rates and heavier cocoon weights than those fed cassava leaves. Increased population density reduced survival rates, cocoon weights, and fecundity. The optimal population density for rearing was 30 individuals per container. These findings provide valuable insights for improving S. c. ricini rearing practices. Using castor leaves as the primary diet and maintaining an optimal population density of 30 individuals per container can enhance survival and cocoon quality. This information is particularly useful for small-scale and laboratory rearing efforts, contributing to the sustainable development of S. c. ricini cultivation and silk production.

Abstract

For demographic studies of organisms, life tables are one of the most appropriate tools that help in presenting the patterns of birth, death, survival of progeny and also the life expectancy. Life tables can be constructed based on the sexes in relation to the ecological drivers that include both biotic and abiotic factors. Helicoverpa armigerais a highly destructive pest affecting the major food crops such as pulses, fruit crops, oilseeds etc. all over the world. In India it is cosmopolitan. The estimated yield loss in India is about nearly 38%. An attempt has been made here to review the information generated in some recent works regarding the population studies of this polyphagous pest and its management in India.

Abstract

Tomato (Lycopersicon esculentum) is one of the most widely grown vegetables globally. Integrated pest management, which combines multiple control methods, is commonly used to tackle fruit fly infestation. The experiment conducted at Abdul Wali Khan University Mardan, Pakistan in 2022, evaluated the efficacy of Alphacypermethrin, Basil Extract, and a Control treatment against Atherigona orientalis in tomato cultivation. Using a Randomized Complete Block Design (RCBD) with five replicates, the study assessed the effects of these treatments on pest populations and tomato yield. Alphacypermethrin proved to be the most effective in reducing larval, pupal, and adult infestations, leading to a significant increase in healthy fruit yield. Basil Extract showed moderate effectiveness, while the Control treatment exhibited higher infestation rates and lower yield. These findings suggest Alphacypermethrin as a reliable pest control agent, with Basil Extract as a sustainable alternative or supplementary option within Integrated Pest Management (IPM) strategies. Future work should explore the integration of both treatments and evaluate their long-term environmental impacts.

Abstract

This study evaluated the efficacy and economic viability of four concentrations of Movento® SC insecticide-Movento® 30 SC, Movento® 60 SC, Movento® 120 SC, and Movento® 240 SC-against mustard aphids infesting Brassica napus at the Agriculture Research Institute Tarnab farm during the 2021-2022 growing season. The study was conducted during the growing season of 2021-2022, with different concentrations of Movento® SC applied to control mustard aphids on Brassica napus. The research used a factorial randomized complete block design (RCBD) with two factors. Results indicated that diet type and population density significantly influenced the biological parameters of S. c. ricini. Silkworms fed castor leaves exhibited higher survival rates and heavier cocoon weights than those fed cassava leaves. Results revealed that Movento® 60 SC was the most effective in managing mustard aphids, resulting in the lowest aphid infestation level and the highest crop yield of 8526.7 kg/ha. This treatment also provided the highest net benefit of Rs.161,315.10/ha, with a cost-benefit ratio (CBR) of 18.50. While Movento® 120 SC and Movento® 240 SC were also effective in controlling aphids, they were less cost-effective than Movento® 60 SC. Movento® 30 SC showed the highest aphid infestation and the lowest economic returns. Movento® 60 SC provided the best combination of efficacy and economic benefit in managing mustard aphids in Brassica crops. It resulted in the maximum yield and net benefit, making it the most economically viable option. Although Movento® 120 SC and Movento® 240 SC were effective, they proved to be less cost-effective when compared to Movento® 60 SC. This suggests reassessing pest management strategies to balance optimal pest control with greater economic returns in mustard cultivation.

Abstract

Barley Shoot Fly (BSF) Delia Arambourgi Seguy causes tremendous yield loss in barley. Five foliar and two seed dressing insecticides were evaluated on variety HB-1307 against shoot fly at Debre Birhan Agricultural Research Center DBARC and Ankober station in 2021, the primary cropping season. The experiment aimed to select an effective and economical insecticide for barley shoot fly. Randomized Complete Block Design with three replications was used for the study, and data were analyzed using R software with a generalized linear mixed-effect model. Treatment means were separated using Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Seed dressing insecticides were applied on barley seed immediately before planting, and insecticides were used according to factory recommendations. Combined result showed that from foliar insecticides lambda cyhalothrin 5% EC, from seed dressing insecticides Thiamethoxam 25% WG were effective in decreasing the number of larvae and dead heart shoots, and gave maximum marginal rate of return and higher net benefit than the rest of the treatments. Therefore, we recommend proper use of Lambda cyhalothrin 5% EC at a rate of 0.25 lt/ha using 200 L water/ha and 4 g Thiamethoxam 25%WG 1/kg seed dissolved in 600 ml water for effective management of barley shoot fly.  Based on this finding, examining sowing date and seed dressing insecticides in future research may provide yield increments in barley.

Abstract

Coffee is an exported commodity that is important in earning foreign exchange. The coffee berry borer (Hypothenemus hampei) is the most crucial pest that has a detrimental effect on coffee growers in Indonesia. Research on the incidence of fruit borer on Arabica and Robusta coffee was carried out on smallholder plantations in the Tanah Datar district. The study aimed to determine the extent to which fruit borers infest Arabica and Robusta coffee, and to determine the populations of these pests so that they could be compared. Observation variables included planting conditions and cultivation methods, percentage of coffee plants infested, percentage of coffee cherries, insect identification in the laboratory, and coffee berry borer populations. The results showed that the average incidence of Hypothenemus hampei infestation on Arabica coffee plants in Tanah Datar district was 30.00% and 36.66% on Robusta coffee plants. The percentage of the egg stage in Arabica coffee is 37% and 27% in Robusta coffee. The percentage of the larval stage in Arabica coffee is 33%, and in Robusta coffee, it is 28%. Stadia Pupa on 20% Arabica coffee, 11% Robusta coffee. Stadia imago on Arabica coffee 54%, Robusta coffee 49%. This study provides important insights for integrated pest management strategies in Tanah Datar, particularly in optimizing pest control for Arabica and Robusta coffee.

Abstract

Insect diversity in plantations is crucial for understanding the ecological roles of each species and managing pest-related issues. This study aimed to assess the diversity of insects in Siam citrus (Citrus nobilis Lour.) plantations in Sungkai, Padang City, Indonesia, focusing on the implications for pest management. A survey was conducted in the Siam citrus plantation, categorizing sampling sites into three groups based on the distance from the forest (20, 40, and 60 m from the forest). Insect samples were collected by spraying the plants with insecticides, hand-picking, and trapping insects on a white cloth. The results showed that the number of insect species found at the sites was 19, 18, and 12 at 20, 40, and 60 m from the forest, respectively. The species identified included Bractocera spp., Toxoptera sp., Aphis gossypii, Bothrogonia sp., Planococcus citri, Sanurus sp., Rhynchocoris humeralis, Conocephalus sp., and Valanga nigricornis as pests, and Blattella sp., Hemithyrsocera sp., Coccinella transversalis, Nylanderia sp., Polyrhachis sp., Dolichoderus sp., Anoplolepis gracilipes, Hierodula sp., and Hierodula sp1 as predators, with Lasioglossum sp. identified as a pollinator. The species diversity at each site was categorized as medium, with diversity index values of 2.10, 2.07, and 1.95, respectively. Species evenness was categorized as high, with index values of 0.71, 0.72, and 0.78, respectively. This study provides valuable data on the pest and predator populations in citrus plantations, which can inform sustainable pest management strategies to improve crop health and productivity.
