Aims: This study aimed to assess (i) the perception of Kwa Vonza farmers regarding the presence of termites in their land, (ii) the perceived importance of termites, and (iii) how they control termites in their properties. Study Design: This study is based on responses to a questionnaire sent to farmers. Place and Duration of Study: The study took place in Kwa Vonza Location, Yatta Sub County, Kitui County, Kenya, between April and November 2017. Methodology: 60 questionnaires, each comprising 20 multiple-choice questions, were sent out to farmers. Out of these, 54 responses were received. Where the response did not require a Yes or No answer, it elicited a response from a standardized five-point scale to demonstrate agreement with the provided proposition. Data analysis was done using descriptive statistics, in which percentages were tabulated, and frequency tables were generated using Microsoft Excel. Results: 73% of farmers perceived their land as infertile, with the causes ranging from soil erosion, drought, and mono-cropping. 87% of farmers acknowledged termite infestation in their farms but perceived them as destructive. Termite infestation was attributed to deforestation, drought, and flooding. Chemical control was the method of choice to manage termites. Conclusion: Kwa Vonza farmers do not perceive termites as of any agronomic significance but view them as destructive agents. Further research to address the complex issue of soil management at the farm-scale level that involves farmers is necessary to fill gaps in scientific knowledge and produce advice for practical use.

Purpose High population growth and the expansion of industry from time to time produce a large amount of waste/pollution, which harms global environmental health. To overcome the above problems, soil feeding (mound/nest) builders of termite gut bacteria execute thriving since they can be obtained easily, available, and at low costs. The purpose of this review is to provide evidence of bacteria in the soil feeding termite gut and its potential role in various applications including reduction of methane gas emission, bio bocks/production of bricks, biomedicine, biocontrol (promising tool for sustainable agriculture), and bio-fertilizer (improve the fertility of the soil) and plant growth promote effectiveness all year. Methods This review was progressive in that it assessed and produced peer-reviewed papers related to bacteria in the soil feeding termite gut and its potential role in different applications for an environmentally sound. Based on the findings of reputable educational journals, articles were divided into four categories: methods used to distributions of soil-feeding termites, termite caste system, bacterial diversity, and strain improvement of bacteria in the termite guts for enhanced multipurpose and techniques. Results The bacterial diversity from termite guts of soil feeding termite caste systems/differentiations is vital for snowballing day to day due to their low cost and no side effect on the public health and environment becoming known improvement of the microbial bacteria rather than other microbes. So termites function as “soil engineers” in tropical agroforestry ecosystems that are of great benefit for economic importance to greener approach. Conclusion The present findings indicate that recovery was chosen as an appreciable bring out the bacteria in the soil feeding termite gut and its potential application of termite mounds/nests biotechnological applications. Because of the large amount of nutrients that have built up in termite embankment soil feeding, this type of termite is now known as a “gold-leaf excavation” for bacterial concentrations. This provides the assertion that termite insects are important from an ecological standpoint since they aid in nutrient flows in the ecosystem as a useful tool for various species.

The expansion of plantations may be compromised by climate change, altering the frequency and intensity of precipitation. This study aimed to evaluate the influence of potassium and sodium fertilization and water deficit on the apparent density property and anatomical characteristics of Eucalyptus grandis wood. Six treatments varying in fertilization and rainfall incidence were evaluated. Apparent density testing was conducted via X-ray, while the anatomical features of fibers and vessels were examined through image analysis using a polarized light microscope. Cartography was also performed to map the density variation along the trunk in longitudinal and radial directions. Trees without fertilization exhibited higher apparent density, whereas those with partial rain exclusion displayed less homogeneous wood. Overall, treatments involving potassium and sodium showed no significant difference between them and resulted in a thinner secondary wall. The results indicate that water deficit and fertilization methods significantly impact wood properties.
