Summary: The study identified multiple known biotypes of soybean aphids within single fields in Minnesota, with up to three different biotypes found in one field. Two biotypes were found in five fields, while only one field had a single biotype. Additionally, three isolates showed reactions different from known biotypes, highlighting the importance of characterizing soybean aphid biotypes in small geographical areas.

Summary: This study characterized host-plant resistance in soybean to determine its antibiosis and antixenosis categories of resistance to different biotypes of A. glycines. The tested plant introductions showed variation in the strength of antibiosis towards different biotypes, and all manifested antixenosis in addition to antibiosis. These findings contribute to developing strategies for future deployment of resistant cultivars developed from these plant introductions.

Summary: Spectral remote sensing can enhance the scouting and management of soybean aphids by utilizing linear support vector machines (SVMs) to accurately classify hyperspectral samples. The findings show that a combination of wavelengths at 780 nm and 1,010 nm yields the best performance for identifying the presence of aphids.

Summary: Crop wild relatives (CWRs) have high genetic diversity compared to domesticated descendants. Soybean has over 20 species of CWRs, with Glycine soja being the only wild relative in the primary gene pool with traits transferrable to soybean, including resistance to insect pests such as the soybean aphid. Challenges in accessing high-quality soja germplasm for soybean improvement and strategies for exploiting aphid-resistant soja accessions for pest management are discussed in this review.

Summary: The study evaluated different 2-leaf sampling units and found that two randomly selected leaves from the middle stratum were more accurate in estimating sugarcane aphid density. Some sampling units showed high variability in estimating aphid density across different growth stages, while the (L1+U1) sampling unit demonstrated good accuracy in assessing variation in aphid density.

Summary: This study used electropenetography to examine the effects of two plant viruses on soybean aphid feeding behavior. The results showed little impact of soybean mosaic virus, but significant differences were observed in aphids feeding on bean pod mottle virus-infected plants. These findings contribute to further research on virus transmission and the impact on soybean aphid populations.

Summary: A diagnostic kit based on the glass vial bioassay has been developed for the rapid detection of resistance to various insecticides in Aphis gossypii. This diagnostic tool can quickly and accurately determine effective insecticides, making it significant for pest control and insecticide resistance management.

Summary: The woolly apple aphid is a major pest of apple trees and the generation of its chromosome-level genome assembly provides a valuable resource for research in various areas such as insect-plant interactions and pest resistance management. The phylogenomic analysis reveals the evolutionary relationships of woolly apple aphid with other aphid species, highlighting its importance in the aphid subfamily Eriosomatinae.

Summary: Globally, 27 aphid species have developed resistance to nearly 100 insecticide active ingredients. This study focused on the cowpea aphid (Aphis craccivora Koch) in Australia, which has shown resistance to multiple insecticides. The researchers conducted toxicity tests on different populations of A. craccivora against four insecticides and found alpha-cypermethrin to be the most effective. They also suggested proactive management and increased reliance on non-chemical pest control methods for A. craccivora.

Summary: The study found that the genetic structure of the black citrus aphid population in China is relatively stable, with some genetic differences among populations but no apparent lineages. There is a high positive correlation between geographic distance and genetic distance, indicating recent population expansion events may have occurred in A. aurantii.

Summary: The study identified differences in QTL for main stem node number at different plant densities, with some QTL showing repeated responses to density. Thirty QTL were consistently detected across different methods, densities, and environments, and several loci were predicted to be associated with main stem node number.

Summary: A molecular diagnostic technique has been developed to accurately differentiate 11 aphid species in citrus cultivation. This technique allows for accurate and simple identification of aphids at any life stage, and can be a useful tool for monitoring economically important aphid populations.
