“…The area of attack by these pests in the 2013 planting season reached 0.1% of the soybean planted area [9]. Pests damage soybean leaves and pods and cause yield reductions of up to 25% [10]. According to Rustam [11], every year, pest attacks cause a 15 to 20% loss in soybean production, both directly and indirectly.…”

Many pests attack soybean plants and can cause high-yield losses. To reduce crop damage, using chemicals in the field can potentially cause harmful effects on the environment. Using traps-crops, and biopesticides will be tested as an effective and safe control method. The research was done in the dry season of the tidal land of Tumih Village South of Kalimantan. The design used was RCBD which consisted of six treatments and was repeated four times. The treatment tested were 1). Check, 2). Biopesticides 6 times, 3). Biopesticide 4 times, 4). Biopesticides 6 times + mung bean as trap crop 6%, 5). Biopesticides 4 times + mung bean as trap crop 6%, 6. Insecticides 6 times. The results indicated that armyworms Spodoptera litura and Lamprosema indicata were important pests. Armyworm attacks in the vegetative phase reached 82%. However, the yields obtained were around 2,069 to 2,463 t/ha. Soybean yields in treatment plots with 6% trap crop were 1,664 to 1,969 t/ha. Anjasmoro varietal is not recommended In endemic areas of the armyworm.

“…The percentage of crop loss due to S. litura attack on plants can vary depending on the type of plant attacked, the intensity of the attack, and the plant's growth phase during the attack. Some studies have shown that S. litura attacks can cause a yield reduction of up to 20-30% on some plants, such as tobacco and soybeans (Gaur & Mogalapu, 2018). However, on other plants such as cotton, the percentage of yield loss due to S. litura attack can be higher, reaching 50% or even more (Gaur & Mogalapu, 2018).…”

Significant yield losses can also occur if S. litura attacks during the early growth phase of the plant or during the flowering and fertilization period.…”

This research aimed to evaluate the effectiveness of turmeric extract as a botanical insecticide on the feeding activity and mortality of Spodoptera litura larvae. The method used in this study was a toxicity test using the leaf dip method. The experiment employed a completely randomized design with combinations of turmeric extract concentrations (0, 4, 8, 12, and 16 grams per liter of water) and instar types (1 and 2). The results showed that the application of turmeric extract on cabbage leaves reduced the feeding activity of instar 2 and 3 larvae. Meanwhile, the turmeric extract had an effect on the mortality of instar 2 and 3 larvae only at a concentration of 16%. The symptoms observed in the dead larvae were changes in color and body texture. The conclusion of this research is that 16% is the minimum effective concentration of turmeric extract on instar 2 and 3 S. litura larvae. This study should be continued on other instar types at the field scale.

“…Globally, the cropland system has been facing a series of environmental (Wang C. et al, 2021), socio-economic (Ullah and Uddin, 2021), and institutional (Niedertscheider et al, 2014) disturbances and shocks. For example, plant diseases (Gokulnath and Devi, 2021), insect pests (Gaur and Mogalapu, 2018), changes in market access (e.g., trade war and policy barriers) (He et al, 2019), land-use policies, and management measures (Mittenzwei and Øygarden, 2019) constantly affect agricultural production of the cropland system. Especially, extreme weather (such as drought, flood, and frost) caused by climate change has the most extensive and severe impacts on the cropland system (Kotzee and Reyers, 2016;Rey et al, 2017;Bombi, 2018;Yu and Wu, 2018).…”

Evaluation of Cropland System Resilience to Climate Change at Municipal Scale Through Robustness, Adaptability, and Transformability: A Case Study of Hubei Province, China

et al. 2022

A cropland system is one of the most sensitive socio-ecological systems to climate change, such as drought and flood. Facing frequent extreme weather events worldwide, how to improve cropland system resilience to climate change (CSRCC) and thus ensure food production has been concerned. Although a small number of studies have attempted to evaluate CSRCC through single or multiple indicators, few studies have considered the perspective of the three basic capacities of resilience (i.e., robustness, adaptability, and transformability), which could ignore the dynamic characteristics of cropland system resilience against shocks within a certain period. Therefore, this study first constructs an evaluation index system from the three capacities of system resilience. Then, taking Hubei province, China, as a case and comprehensively using the methods of Delphi, AHP, and TOPSIS to assess the spatio-temporal characteristics of CSRCC at the municipal scale from 2011 to 2018. On this basis, the regional disparities of CSRCC are analyzed by using the Theil coefficient. The results show that the CSRCC of Hubei province fluctuates on a downward trend, with the lowest in 2017 and the highest in 2013. Most municipalities have witnessed a pattern of fluctuated decline, except for a few ones in the plains, such as Wuhan and Jingmen. Generally, municipalities in the plains have greater scores, while some municipalities in the southern and eastern hilly regions show higher adaptability and transformability. In addition, adaptability contributes the least to the CSRCC at the municipal scale. At last, indicator selection against different research objects, influencing mechanism of CSRCC, and policy implications are discussed. This study is expected to provide a reference for the practice in sustainable management and utilization of cropland systems.
