“…In general, insects attempting to colonize plants with antibiosis resistance, that is, plants with the capacity to affect their biology, present reductions in size and weight, diverse deformities, and prolongations in the lifecycle phases and, consequently, high mortality rates (Painter 1951). In the present study, the incubation period of the whitefly eggs in some of the evaluated genotypes was observed; in similar studies, the incubation period of the eggs of B. tabaci biotype B in bean genotypes ranged from 8.00 to 11.00 days (Torres et al 2012;Peixoto and Boiça Júnior 2014). In the present study, the Tybatã and Pérola genotypes had the shortest incubation periods (8.40 and 8.66 days, respectively), consistent with the study by Peixoto and Boiça Júnior (2014), who observed that the incubation periods for these two genotypes ranged from 8.03 to 8.59 days.…”

“…This may be due to a lower nutritional adequacy or the presence of antibiotic factors in this genotype, which are aspects that must be better investigated in future studies. Based on the available literature, the duration of the egg to adult period varies between bean genotypes, and there are reports of periods between 16.20 and 41.00 days (Oriani and Lara 2000;Torres et al 2012). Some references reported a large variation in the development period of the whitefly on cowpea genotypes (Cruz et al 2014), cabbage (Villas Bôas et al 1997), cotton (Prado et al 2015), soybean (Cruz and Baldin 2016), tomato (Baldin et al 2005), squash varieties (Baldin and Benduzzi 2010), melon (Baldin et al 2012) and, more recently, peppers, where a duration of 30.25 days was observed (Pantoja et al 2018), similar to the present study.…”

Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis

The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM) program. The biological development of B. tabaci confined to 17 bean genotypes was evaluated in greenhouse trials to verify the occurrence of antibiosis. Whitefly adults were released on plants of these genotypes to oviposit, afterward the incubation period of eggs, nymphal period, complete development period (egg-adult), and viability of the silverleaf whitefly nymphs were recorded. As main results, genotype CHIP 300 prolonged the developmental period from egg to adult (~10 days) and BRS Estilo, Arcelina 4, IPR Garça, Tybatã, CHIP 300, IPR Eldorado, H96A102-1-1-1-52, SCS-202-Guará and CHIB 06 caused nymphal mortality, suggesting high levels of antibiosis and/or antixenosis. These genotypes may be helpful in common bean breeding programs aimed at developing commercial cultivars resistant to B. tabaci biotype B.

O feijoeiro comum, Phaseolus vulgaris L., constitui importante fonte de proteína e renda para muitos países, entre eles, o Brasil. Diferentes fatores contribuem para a redução da produção, como os insetos pragas, destacando-se Bemisia tabaci (Genn.) biótipo B. O presente trabalho teve por objetivo identificar genótipos de feijoeiro comum resistentes à B. tabaci biótipo B e os tipos de resistência envolvidos. Para isso, foram realizados dois experimentos desenvolvidos em laboratório e em casa-de-vegetação, avaliando-se 11 genótipos de feijoeiro comum. Para o teste com chance de escolha, o delineamento utilizado foi o de blocos casualizados, e para os testes sem chance de escolha e antibiose, a escolha foi pelo inteiramente casualizado, totalizando seis repetições para cada teste. As variáveis avaliadas foram: período de incubação dos ovos; período ninfal; período de ovo a adulto; viabilidade de ovo a adulto e longevidade de adultos. O genótipo IAC-Harmonia prolongou os períodos ninfal e de ovo a adulto de B. tabaci biótipo B. Os genótipos testados foram igualmente ovipositados pela mosca-branca, em testes com e sem chance de escolha.

BACKGROUND: The cashew whitefly (CW), Aleurodicus cocois, is an important pest of cashew in Brazil. The use of resistant plants may be an effective strategy for the control of this pest. In a preliminary assay, we found that dwarf-cashew clones show different levels of resistance to CW. Here, we hypothesized that such resistance is associated with morphological characteristics of cashew leaves and their content of phenolic compounds. RESULTS: We determined (i) the attractiveness and suitability for oviposition of five dwarf-cashew clones towards CW, (ii) the leaf morphology and chemistry of those clones, and (iii) the relationship between leaf characteristics and resistance to CW.In greenhouse multiple-choice assays, PRO143/7 and CCP76 showed, respectively, the lowest and highest counts of both CW adults and eggs. Scanning electron microscopy (SEM) analysis revealed that PRO143/7 and EMBRAPA51 have, respectively, the highest and lowest numbers of leaf glandular trichomes. We found a negative correlation between number of trichomes in the abaxial surface of cashew leaves and CW oviposition. In addition, confocal microscopy analysis and histochemical tests with ferrous sulfate indicated a higher accumulation of phenolic compounds in the resistant clone PRO143/7 relative to the other clones. Dwarf-cashew clones did not significantly differ based on the number of leaf epicuticular striations, and the thickness of both leaf lamina and the epidermal layer. CONCLUSION: The resistance of dwarf-cashew plants to CW is associated with an elevated number of trichomes and accumulation of high levels of phenolics in leaves. Additionally, the contribution of epicuticular striation density and thickness of leaf lamina/epidermal layer are insignificant.
