“…Tomato production is affected negatively by numerous pests which result in poor yield, low quality, and financial loss. Ahmed et al (2022) reported about 200 species of insect pests attacking tomatoes in Egypt. The major pests include aphids (Aphis gossypii), white flies (Bemisia tabaci), thrips (Thrips tabaci), leaf miners (Lyriomyza spp and Tuta absoluta), and the fruit worms (Helicoverpa armigera) (Kollie et al, 2014;Brévault et al, 2014).…”

Helicoverpa armigera is among the major insect pests that pose a threat to tomato production in Nigeria with an insufficient understanding of its population parameters, and available environmentally friendly control materials which are essential for the development of reliable and sustainable management strategies that can minimize the frequent use of synthetic pesticides; which are hazardous to the environment, non-target organism, and humans. The present study was conducted with the objectives of establishing population abundance and dispersion of H. armigera. Surveys were conducted in the savannah agroecological zone of Nigeria through fortnightly field visits to tomato farms from July to September 2019 (rainy season), and month of December 2019 to March 2020 (dry season), making a total of seven (7) and Nine (9) visits respectively. Ten plants were randomly selected and tagged from each farm, for observation of the presence of H. armigera larvae on the upper and lower parts early in the morning (6:00-7:30 am) on all sampling. Numbers found on each plant were counted and recorded with dates. Data obtained were subjected to analysis of variance and the least significant difference (LSD) at 0.05% level of probability was used to separate significant means. Data were further used in calculating the various dispersion indices. The result indicates that H. armigera was higher at 8 weeks after planting and aggregated on the upper part of the plant with a higher population in the dry season. Abundance and dispersion indices of H. armigera on tomato plants reported in this study will provide for appropriate decision-making in designing eco-friendly management of the pest.

“…In contrast, the estimated loss due to Fusarium stalk rot has been reported as 38% in total yield ( Bellini et al., 2023 ). The animal manure is rich in organic matter content, total biological activity and actinomycetes populations, fluorescent pseudomonads and fungi demonstrated by ( Abd El-Mageed et al, 2022 ; Abd El-Aty et al, 2022a ; Abdou et al, 2022 ; Abo Sen et al, 2022 ; Ahmed et al, 2022a ; Ahmed et al, 2022b ).…”

Fusarium verticillioides, an important maize pathogen, produce fumonisins, causes stalk rot and consequentially reduce crop growth and yield. Therefore, herein we aimed to evaluate the potential use of two farmyard soil organic manures, i.e., fresh (5-6 days old) and stored (5-6 months old) organic manure, to manage F. verticillioides infections as well as borer incidence and lodging in maize plants. After 30, 60, and 90 days of sowing, samples of soil, roots, and stems were collected to isolate F. verticillioides. Moreover, we estimated ear and kernel rot induced by F. verticillioides at the final harvest. Fresh organic manure treatment increased infection rates of F. verticillioides in soil, roots, stem and kernels compared to the control treatment. In contrast, stored organic manure plots treatments decrease F. verticillioides frequency. At 90 days after sowing, stored organic manure suppressed the survival of F. verticillioides, which reduced the F. verticillioides incidence percent. These results were similar to the effect of herbicides-and insecticide-treated plots demonstrated, which show a significant decrease in F. verticillioides incidence rates. Mycological analysis on symptomless kernels revealed a higher % of pathogen infection in opened husks variety (Balady) than closed husks variety (SC10). Compared with stored organic manure, the stem borer incidence and lodging percentage were the highest in fresh organic manure plots. Finally, these results demonstrated that storing organic manure within five to six months as farmyard manure led to high-temperature centigrade within organic manure, thereby destroying spores of F. verticillioides, whereas fresh organic manure did not.

“…Plant chemicals either directly kill insect pests (Ayvaz et al 2010) or have repellent (Isman 2006, Lee 2018, antifeedant (Koul 2008), and fumigation effects (Trivedi et al 2017, Mwamburi 2022. Essential oil derived from different parts of plant species have been utilized to tests against various arthropods Tak 2016, Awad et al 2022) including insect pests (Innocent and Hassanali 2014, Lengai et al 2019, Ahmed et al 2022. Among different insect pests, Coleopterans were most studied against essential oils of plant followed by Lepidoptera (Campolo et al 2018).…”

This study aimed to evaluate the efficacy, toxicity, and effectiveness of clove bud oils against Sitophilus zeamais in the stored maize variety Manakamana-4. The toxicity evaluation of the oil on maize weevils were conducted in completely randomized design (CRD) with eight treatments including seven different oil concentrations (10%, 5%, 2.5%, 1.25%, 0.625%, 0.3125% and 0.15625%) and control replicated four times at laboratory conditions in National Entomology Research Center, Khumaltar, Lalitpur, Nepal during 2020/2021. The results exhibited higher toxicity of clove oil to weevils after 72 h of oil exposure. Higher concentrations and longer exposure periods resulted in an increased mortality rate. Lower concentrations required a longer time for 50% of the weevil population to kill, whereas higher concentrations required a shorter time. Moreover, the essential oil was effective in causing the mortality of the weevil population at all three time intervals of 6, 10, and 16 days with varying mortality rate as lower concentrations required extended exposure time. In the same way, repellency assays of clove oil by applying four different concentrations (10%, 5%, 2.5% and 1.25%) on Whatman filter paper showed significant pest repellant activity. Repellent action was also highly dependent upon oil concentration and exposure time showing highest repellent activity (98.75%) at 10% concentration at 24 h interval. Additionally, it indicated higher the concentrations of clove oil higher the seed germination and fewer the weevil progeny emergence, and vice-versa. Since clove oil is considered to have low mammalian toxicity and a minimum risk pesticide, it can be incorporated into integrated pest management system in storage against maize weevils.
