Summary: This study investigates the interaction between cowpea plants and aphids and identifies the genes underlying cowpea resistance to aphids. The results show that the feeding behavior of aphids remodels the transcriptome of cowpea and that this remodeling depends on both the duration of feeding and host-plant resistance. The study also identifies candidate genes involved in aphid resistance, including both conventional resistance genes and novel genes.

Summary: This study evaluated the resistance response of cowpea to the cowpea aphid and found that the aphid has phytotoxic effects on cowpea. However, resistance traits can effectively counteract aphid damage and limit their reproductive potential.

Summary: This study demonstrates that the resistance against soybean aphids conferred by Rag5 is likely derived from stems, as evidenced by experiments showing reduced aphid populations in Rag5/rag5 chimera and poor aphid performance in detached stem plus leaf assays. Gene expression analysis also revealed upregulation of the isoflavone kaempferol biosynthesis in resistant Rag5 plants, with supplementation of kaempferol restoring resistance in detached stems of plants carrying Rag5.

Summary: This study screened G. arboreum and G. hirsutum genotypes for resistance against cotton-melon aphid. Ten G. arboreum genotypes and two G. arboreum genotypes showed significant antibiosis effects, while G. arboreum also exhibited tolerance to aphids. These findings can contribute to the development of commercially cultivated cotton with aphid resistance.

Summary: By evaluating the preference and ecological parameters of Lipaphis erysimi on Brassica fruticulosa and its introgression lines, we found that these introgression lines possess resistance mechanisms, possibly achieved through a synergistic combination of antixenosis and antibiosis mechanisms.

Summary: The study investigated the susceptibility of fourteen eggplant cultivars to green peach aphid (M. persicae), identifying 'Long-Green', 'Ravaya', and 'Red-Round' as relatively resistant and 'White-Casper' and 'Pearl-Round' as susceptible cultivars. 'White-Casper' exhibited the highest hosting preference in antixenosis tests, while 'Long-Green' showed the least susceptibility among the tested cultivars.(Parameter r(m)) was the highest on 'White-Casper' and the lowest on 'Long-Green'. The research highlights the importance of selecting resistant cultivars in the integrated pest management of green peach aphid.

Summary: This study identified pea lines and putative genes with resistance to pea aphids (PA) through experiments on 301 pea varieties collected from around the world. A total of 48 lines were classified as Cluster 2 with the lowest aphid fecundity, and the 'Lifter' variety showed the best resistance. By using genome-wide association mapping, SNPs and candidate genes associated with resistance to adult, nymph, and total number of PA were identified. These findings can be applied in targeted breeding programs to develop resistant pea varieties.

Summary: Host plant resistance is a promising alternative to aphidicides for controlling bird cherry-oat aphid infestation in wheat. Various experiments were conducted to determine the resistance mechanism in diploid Aegilops tauschii accessions, revealing a combination of antixenosis and antibiosis as the main factors contributing to resistance against Rhopalosiphum padi.

Summary: This study found that fertilizers and abscisic acid (ABA) have negative effects on the growth and reproduction of the cabbage aphid. The ABA-treated fertilized plants showed increased secondary metabolite content, which inhibited the aphid's avoidance and adaptation abilities.

Summary: Soybean seeds are a significant source of protein and oil, and the levels of these compounds are regulated by quantitative trait loci (QTL). This study identified QTL related to protein and oil content in soybean seeds and identified specific genes associated with these traits through genetic analysis.

Summary: This study examined the oviposition preference and larval performance of Helicoverpa armigera on three cultivars of short-duration pigeonpea. The results showed that H. armigera laid similar numbers of eggs on all three cultivars, but moths laid slightly more eggs on ICPL 88039 under choice conditions. Larval growth and development were affected by cultivar, with larvae growing to the largest size and developing fastest on ICPL 86012.
