“…For example, pea aphids (Acyrthosiphon pisum Harris; Hemiptera: Aphididae) when fed on a resistant legume variety had significantly higher number of potential drops compared to the pea aphids that were fed on a susceptible legume variety (Gao et al 2008). Similarly, soybean aphids feeding on soybean genotypes that exhibit antibiosis and antixenosis had significantly higher number of potential drops compared to the soybean aphid-tolerant and susceptible genotypes (Baldin et al 2018). Taken together, these studies suggest that the brief sampling of cells by aphid stylets eventually lead to host plant acceptance or rejection, and the higher number of potential drops has been correlated with enhanced resistance to aphids (Tjallingii 2006;Chandran et al 2013;Baldwin et al 2018).…”

The greenbug, Schizaphis graminum, is a serious pest of sorghum (Sorghum bicolor). For the past several decades, resistant sorghum hybrids have been used to control greenbug populations. However, the durability of plant resistance is frequently challenged by evolution of new greenbug biotypes, and there is a continuous need for screening of resistant germplasm for its effective management in the field. Natural variation in sorghum plants/populations provides distinct approaches to identify novel sources of resistance against greenbugs. In this study, we used the recently developed sorghum nested association mapping (NAM) population parental lines to understand sources of sorghum resistance to greenbugs. Using choice and no-choice assays, we have identified SC265 and Segaolane as the resistant and susceptible lines, respectively, to greenbugs compared to the wild-type plants. The Electrical Penetration Graph (EPG) analysis revealed that the greenbugs spent significantly lesser time in the xylem and sieve element phases while feeding on the resistant NAM parental line, SC265, compared to the susceptible (Segaolane) and wild-type (RTx430) sorghum lines. In addition, the EPG results indicated that there is no significant difference in the time to first probe, time to reach first sieve element, pathway phase, and non-probing phase among the three sorghum plants, which suggests that the resistance factors present in the vascular tissues of the resistant line (SC265) potentially contribute to the resistance mechanisms against greenbugs. Overall, SC265 NAM parental line showed a combination of antixenotic and antibiotic-mediated resistance mechanisms against greenbugs, whereas the susceptible line Segaolane displayed the least resistance to greenbugs.

“…The EPG method can be used to obtain detailed information on resistance factors (van Helden et al, 2000; Le Roux et al, 2008), enabling studies on sucking insect behavior during the stylet penetration of the plant tissues and, based on the characteristic waves generated, to establish correlations with physical and/or chemical resistance features of the plants (Tjallingii, 1988; Hardie & Powell, 2000; van Helden et al, 2000). Apart from the establishment of resistance factors, the EPG technique also allows the separation of antixenosis and antibiosis (Baldin et al, 2018).…”

“…Both electrodes were connected to a signal amplifier (Giga‐8 DC EPG), with a resistance of 109 Ω and an adjustable voltage unit (Diaz‐Montano et al, 2007; Baldin et al, 2018). To avoid interferences and better resolution in the records during the monitoring process, the insects, plants, and probes remained inside a Faraday cage (Tjallingii, 2006).…”

“…This method has been widely used to study the feeding behavior of aphids (Baldin et al, 2018; Gabrys & Tjallingii, 2002), whiteflies (Civolani et al, 2014), stink bugs (Lucini & Panizzi, 2017, 2018), and psyllids (George et al, 2017) in a variety of crop cultures. The morphological and chemical analysis of plant features associated with the use of EPG can help in the interpretation of sucking insects’ feeding behavior in genotypes with different levels of susceptibility.…”

The cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), is distributed throughout the tropical and subtropical areas of the world. The main crops attacked by B. brassicae are cabbage, collard greens, broccoli, Brussels sprouts, and cauliflower. To survive the attack of pest insects, plants have evolved various resistance mechanisms that may affect pest feeding behavior. The use of electronic monitoring through EPG (electrical penetration graph) can help characterize and distinguish the resistance mechanisms involved. This study evaluated the feeding behavior of B. brassicae in eight genotypes of collard greens, Brassica oleraceae L. var. acephala (Brassicaceae), exhibiting antixenosis and/or antibiosis resistance to this insect. Possible correlations were established between the glucosinolate levels, the hardness, and the epicuticular wax on the leaves vs. aphid feeding behavior. On the genotypes 22V, 5E, and 27VA, for which many 'potential drop' waves were performed, aphid development was slower, indicating antixenosis as resistance type. Aphids on the genotypes 22V and 24X required more time until accessing the phloem, also suggesting antixenosis as resistance category. Genotypes 22V and PE had hard leaves, which also points at antixenosis. Genotypes 20T and HS had higher total wax and wax mg À1 . Feeding parameters on ARI and 24X were similar to those observed on HS; antibiosis is likely to be the predominant resistance category of this germplasm. Because HS was considered as a susceptible standard genotype in this study, a higher gluconapin amount indicates that this compound does not influence cabbage aphid feeding behavior. The present study confirms that analysis of the physical and chemical aspects of collard greens genotypes by the EPG technique can provide a useful approach for the study of plant resistance to cabbage aphids.

The soybean aphid (SBA; Aphis glycines Matsumura) and the soybean cyst nematode (SCN; Heterodera glycines Ichninohe) are major pests of the soybean (Glycine max (L.) Merr.). Independent studies on these pests have made substantial progress in understanding the genetic basis of limiting these pests in both model and non-model plant systems. Classical linkage mapping and genome-wide association studies (GWAS) have identified some major and minor QTLs in soybean. The studies on interactions of aphid and nematode effectors with host proteins allow us to identify molecular cues in various signaling components, including plant disease resistance and phytohormone genes. Here we review various resistance components of both SBA and SCN in terms of their effectors, their role in eliciting or attenuating host defense and update on findings on key quantitative trait loci (QTLs)/genes in soybean that could help in mitigating these widespread shifted virulent soybean aphid and SCN populations. We also provide an update on recent interaction studies of soybean-soybean aphid-SCN as well as interaction studies involving different aphids/nematodes and their host systems. PHYTOALEXIN DEFICIENT4 (PAD4) in soybean could possibly play a major role in providing resistance against both soybean aphid and SCN.
