Rice was an important food crop that one of the cultivation was the jajar legowo planting system. However, the effect of the planting system on brown planthopper and predatory Lycosa has not been well studied, related to microclimate changes. This study aims to identify microclimate factors in the jajar legowo and their effects on brown leafhopper populations and Lycosa. This research was designed through field experiments in rice fields with the treatment of legowo planting system (2: 1) and conventional system as a check. The research variables consisted of temperature, humidity, light intensity, brown leafhopper population, and Lycosa population. The results of this study showed the highest humidity was at the end of the planting period. The temperature and light intensity recorded in jajar legowo planting systems tends higher. The population of Lycosa in the Jajar legowo planting system was highest in the 2 week after transplanting (WAT), while in the conventional planting, the system was found in the 1 WAT The highest brown plant hopper population was recorded at 3 WAT, while in jajar legowo at 2 WAT. The results of this study showed no significant effect of microclimate factors on the Lycosa population and brown leafhopper populations. The benefit of this research is knowing the effect of microclimate on lycosa and WBC populations in Jajar Legowo and Conventional rice planting systems.

“…Corn leaf aphid, Rhopalosiphum maidis is basically a serious insect pest of maize crop but it also attacks wheat crop, and is distributed throughout the world i.e. from tropics to temperate regions causing around 25 to 30% yield loss under severe infestation ( Chandrasekhar et al., 2018 ; Jasrotia et al., 2021 ). Aphids are polyphagous pests and cause damage not only to one crop but also attack weeds from the gramineae, cyperaceae, and typhaceae families.…”

Aphids are one of the most important insect pests of wheat crop in all wheat growing regions of the world. Amongst various aphid species, the corn leaf aphid (Rhopalosiphum maidis F.) is considered one of the most destructive insect pests of wheat in the North Western Plains region of India. Transcriptome profiling of highly susceptible wheat Triticum durum genotype, A-9-30-1 and tolerant wheat Triticum aestivum genotype, HD2967 was performed to investigate aphid-host interactions. The results obtained from differential gene expression analysis of R. maidis on the highly susceptible genotype, A-9-30-1 plants, when compared with the tolerant genotype, HD2967, showed that 212 genes were significantly upregulated and 1009 genes were significantly downregulated. Our findings demonstrated that the genes associated with defense were significantly higher in response to R. maidis on HD2967 as compared to A-9-30-1. Additionally, various genes with physiological attributes were expressed during aphid attack. Based on gene ontology classification, three classifications, such as, cellular components (CC), molecular function (MF), and biological processes (BP) of sequences were identified. KEGG enrichment analysis revealed that twenty-five pathway genes were differentially expressed during the infestation of wheat with R. maidis. Notable changes were observed in A-9-30-1 and HD2967 transcriptomic profiling after infestation. The results obtained in the present study will help to elucidate the mechanism governing host-pest interaction and may lead to the development of new methods for increasing the resistance level of wheat against R. maidis, including over-expression of defense-related genes.

“…Thus, we predicted that pollinators (mainly ground-nesting bees in our study region) and the kleptoparasites that depend on them would be harmed by tillage (as in Ullmann et al, 2016). Conversely the directly of tillage impacts on herbivores, parasitoids, and predators varies widely (e.g., Jasrotia et al, 2021; Rowen et al, 2020; Serée et al, 2021; Wichura et al, 2022).…”

Agricultural diversification often promotes biodiversity and ecosystem services by increasing habitat diversity. However, responses to agricultural diversification are context dependent, differentially impacting functional groups of service-providing organisms and crop yields. Conservation and no tillage are promoted as agricultural diversification practices that increase soil heterogeneity and habitat diversity. Here we investigated whether soil tillage practices in canola crop fields altered arthropod biodiversity or yield, and how effects of field-scale diversification compared to landscape-scale habitat context. We focused on effects of high, medium, or no tillage on five functional groups with unique diets and reproductive strategies: (i) herbivores, (ii) kleptoparasites, (iii) parasitoids, (iv) pollinators, and (v) predators. Effects of agricultural diversification on arthropod abundance and diversity varied across functional groups. Pollinators responded to on-farm soil diversification, benefiting from medium tillage. Predators and herbivores responded most strongly to landscape-scale habitat composition and were more abundant in landscapes with more semi-natural habitat. However, variation in arthropod communities had little effect on canola crop yield, which was lowest in fields with no tillage. Policy implications: Our results indicate that natural history differences among arthropod functional groups mediate how habitat availability affects biodiversity. Crop yields, however, showed no response to biodiversity of ecosystem service providers. Our research highlights the need to determine the contexts in which soil diversification practices meet a multi-faceted goal of simultaneously supporting natural biodiversity, ecosystem services, and crop yield.
