“…In Africa, invasive alien species (IAS) have grown exponentially, througout the years threatening food security and market loss (Sileshi et al, 2019). The introduction of these IAS in Africa has increased as a result of ineffective border biosecurity control measures, capacity constraints and climate change that in uences further spread (Saccagi et al, 2016;Mulema et al, 2021;Kenis et al, 2022;Olago et al, 2023.). Due to its size, agricultural land, and the sharing of land borders with other neigbouring countries (Hurley et al, 2017).…”

Invasive alien pests have caused a considerable negative impact on socio-economic growth and development in the South African agricultural sector. An effective strategy called horizon scanning has recently gained momentum in assessing the preparedness level for prospective changes or threats by invasive alien pests. The study was conducted to identify and prioritize pests already occurring elsewhere in Africa that are likely to be introduced in the Republic of South Africa as well as to develop pest risk analysis reports, pest risk management measures, surveillance procedures, regulatory framework and pest response strategies. The current study revealed that out of 97 known alien invasive arthropods, only 22 invasive pests are considered to have the highest potential risk of being introduced to South Africa. Among these, 8 were Hemiptera, 6 Coleoptera, 5 Diptera, 2 Lepidoptera, one Thysanoptera. Most arthropods (80%) were likely to arrive as contaminants on plant commodities. The pests with the highest scores were Maconellicoccus hirsutus, and Thrips palmi. Both M. hirsutus, and T. palmi have higher potential for entering and establishing in the country as they are important pests of plants. Zygodacus cucurbitae, Bactrocera latifrons, B. zonata, Paracocus marginatus, and Pectinophora gossypiella were the second most economic pests in terms of likelihood of entry and establishment in the country. Complete pest risk assessments and surveillance for the presence or introduction of pests in the country were the most frequently recommended phytosanitary measures against highly prioritised pests with the highest scores. Plants and plant products are the primary pathways for these prioritised pests.

Wheat development in tropical regions faces various obstacles, one of which is biotic stress from pests and diseases. This research aims to determine how these limiting factors inhibit production improvement. The study was conducted in high altitude areas characterized by high rainfall and various organisms that symbiotically adapt to wheat plants. An analysis was performed to assess the impact of biotic stress on the observed response variables. The research arranged in randomized complete block design (RCBD) with 3 replications, using 26 advanced-generation wheat lines derived from convergent breeding and four check national varieties. Results showed that some organisms impacted lodged plants, empty spikelets, and yellow spots on flag leaves. The percentage of empty florets was the most significant factor affecting seed yield. The resistance level to the yellow leaf spot of all wheat lines and varieties was thought to be good because the inoculum of the yellow leaf spot pathogen was still limited. Yield character performance of almost all wheat lines were better compare to the national varieties which were used as control. Lodging frequency and empty florets correlated negatively to seed weight. Empty florets had the strongest direct negative effect on yield compared to other characters.
