Summary: Common beans are staple food in Brazil. Virus diseases transmitted by whiteflies cause significant crop losses. This study developed genetically modified common bean lines with resistance to whiteflies, which resulted in high mortality rates for the insects. The transgenic plants did not affect non-target organisms. This research provides a foundation for the development of whitefly-tolerant common bean cultivars.

Summary: The study conducted in Benin revealed that rice farmers perceived birds, specifically weavers, as the most important rice pests. Different regions of Benin faced varying main pests, with rodent attacks being the most significant rice storage constraint. Farmers predominantly utilized synthetic chemical pesticides for pest control, despite recommendations against their use by the Beninese National Pesticide Management Committee.

Summary: The study aims to identify post-harvest diversity of bean bruchids in two bean-producing regions in Congo, revealing the main pest species Acanthoscelides obtectus and Callosobruchus maculatus. Understanding the bruchid diversity will lead to proposing effective control methods with minimal impact on environment and human health.

Summary: The country bean crop in Bangladesh is severely affected by insect pests and diseases, leading to significant yield losses. The farmers' perceptions of pests and diseases, as well as their management practices, are crucial in establishing effective pest management methods. A survey of country bean farmers revealed that they have been facing pest problems for over a decade, with aphids and pod borers being common pests in all surveyed areas. The farmers heavily rely on chemical pesticides for crop production, and the pests and diseases combined result in considerable yield losses.

Summary: Through transcriptomic analysis and WGCNA, 139 key genes related to resistance of common bean to Xanthomonas axonopodis pv. phaseoli were identified, including genes encoding resistance proteins, transcription factors, oxidoreductase proteins, and plant hormone signal transduction-related genes. These genes play important roles in the resistance to pathogen infection.

Summary: In this study, the response of a Portuguese collection of common bean accessions to powdery mildew infection was evaluated, revealing the presence of different resistance mechanisms. A genome-wide association study identified disease severity-associated genetic variants and proposed candidate genes. This research provides valuable genetic resources for the development of molecular tools and precision breeding for powdery mildew resistance in common bean.

Summary: Research indicates that different biotypes of the pea aphid have varying levels of protection from facultative endosymbionts, with interactions between endosymbionts and parasitoid communities. While parasitoid pressure varies seasonally, its influence on endosymbiont dynamics at a seasonal scale is limited.

Summary: Genetic diversity and structure of common bean germplasm from Serbia was assessed using 27 SSR markers. Results showed higher variability in landraces compared to cultivars. Bayesian clustering model revealed clear separation into Mesoamerican and Andean gene pools, with a small admixed genetic structure group. Subdivision according to seed forms and genetic distance analysis further characterized the bean accessions. This study provides valuable information for conservation and breeding strategies of common bean germplasm in Western Balkans and beyond.

Summary: The family Rhabdoviridae includes various viruses, some of which are human pathogens such as rabies virus, with bats being important reservoirs. In a study in the Republic of the Congo, four new rhabdovirus sequences were discovered in bats, indicating the need for further research and surveillance on rhabdoviruses and bats.

Summary: This paper reviews the diversity of edible insect species and their associated host plants in the Democratic Republic of the Congo (DRC). It explores the consumption patterns and motivations of entomophagy practices in the country, highlighting research gaps and major challenges for the sustainable development of the edible insect market. The study identifies 148 insect species consumed in the DRC, with dominant orders including Lepidoptera, Orthoptera, Coleoptera, and Hymenoptera. The inventory of host plants for major edible lepidopterans reveals 122 species dominated by four plant families. Conservation strategies and mass-rearing methods are needed to protect endangered plant species and support sustainable insect consumption.

Summary: In this study, 17 insect-resistant and 4 insect-susceptible yardlong bean varieties were identified. It was found that the leaves of yardlong beans were the most vulnerable to common cutworms. These insect-resistant varieties can be used to reduce pesticide applications.

Summary: The study assessed the on-farm diversity and cropping system of common bean in the east Hararghe Zone of eastern Ethiopia. Seven farmers' varieties of common bean were identified, with higher diversity in tepid, moist mid highlands. Male adults were primarily responsible for common bean activities, while insect pests were a prominent constraint. Farmers' varieties were used for food, feed, and soil fertility management, underscoring the need for on-farm and ex situ conservation to promote their cultivation.

Summary: Seed traits are important for crop yield, and studying genomic regions can aid in the breeding of common bean varieties. This study on Turkish common bean germplasm found a significant positive correlation between seed width and seed yield/plant and hundred seed weight. Different provinces showed variations in seed traits. Genotyping by sequencing identified several markers associated with seed traits, particularly on chromosome Pv08. These findings provide valuable information for marker-assisted breeding of yield-related traits in common bean.
