Assesing Bemisia tabaci (Genn.) biotype B resistance in soybean genotypes: Antixenosis and antibiosis

Resistance to Dichelops melacanthus (Hemiptera: Pentatomidae) in soybean genotypes of different maturity groups

“…Multiple insect resistance in its genealogy (Silva et al 2013b); resistant to B. tabaci biotype B (Valle and Lourenção 2002) 'Coodetec 208' OC-4 × Williams 20 Commercial susceptible (Silva et al 2013b) Semiearly 'IAC 18' D72-9601 × 'IAC 8' Tolerant to stink bug complex (Lourenção et al 2000) 'IAC 24' IAC80-1177 × IAC 83-288 Antixenosis to B. tabaci biotype B (Silva et al 2012;Valle and Lourenção 2002) 'IAC 100' 'IAC-12' × IAC 78-2318 Antibiosis to P. guildinii (Silva et al 2013b) IAC 74-2832 'Hill' × PI 274454 Antibiosis to P. guildinii (Silva et al 2013b) IAC 78-2318 D72-96-1 × IAC 73-227 Resistant to stink bugs (Rossetto et al 1986;Lourenção et al 1987;Silva et al 2013b) PI 227687 Okinawa, Japan Resistant to stink bugs (Rossetto et al 1986;Silva et al 2013b) Late 'IAC 19' D72-9601-1 × 'IAC 8' Antixenosis to B. tabaci biotype B (Valle and Lourenção 2002); Antibiosis to P. guildinii (Silva et al 2013b) PI 274453 Okinawa, Japan Resistant to stink bugs (Rossetto et al 1986;Silva et al 2013b) PI 274454 Okinawa, Japan Resistant to stink bugs (Rossetto et al 1986;Silva et al 2013b) L 1-1-01 BR-6 × 'IAC 100' Antibiosis to P. guildinii (Silva et al 2013b) 'Conquista' Lo76-44842 × Numbaíra Commercial susceptible (Silva et al 2013b) (Fehr and Caviness 1977). We used second-stage insects because the nymphs of this species present high nymphal mortality in the first instar (Chocorosqui and Panizzi 2008).…”

Evaluation of a low-cost staining method for improved visualization of sweet potato whitefly (Bemisia tabaci) eggs on multiple crop plant species

“…In a different study screening 12 cucumber genotypes for resistance to B. tabaci , significant differences in oviposition were found from a seven-day no-choice assay and those results were strongly correlated to “degree of colonization”, but not as strongly to other measured development parameters [ 16 ]. In a group of ten soybean genotypes, differences in oviposition from a three-day no-choice assay were used to identify a single putative resistant genotype (‘IAC-17’), and other experiments tracking nymph life parameters also found slightly slowed B. tabaci development on that genotype – along with several other soybean genotypes included in the study [ 18 ]. A more recent study in soybean identified four genotypes as resistant, with two of those four selected due to low oviposition values from a three day no-choice assay [ 20 ].…”

The effects of different Charleston pepper cultivars on the demographic parameters and the antioxidant levels of Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae)

“…However, the extensive use of pesticides over the years has resulted in widespread and varied forms of resistance developing (Bass et al, 2014). Hence, there has been a growing emphasis on alternative methods to chemicals, specifically on the use of resistant varieties in recent years (Silva et al, 2012).…”

“…The use of resistant varieties or unsuitable host plants in agricultural production offers significant advantages such as compatibility with other control techniques like biological pesticides or biological agents, environmental friendliness, affordability, and reduction of harmful pest populations (Stansly & Natwick, 2009;Vieira et al, 2011;Silva et al, 2012). This approach can be particularly effective in integrated pest management (IPM) strategies, where multiple methods are used in combination to control pests while minimizing their impact on the environment and human health.…”
