A Rapid Screening Method for Resistance to Anthonomus eugenii (Coleoptera: Curculionidae) in Capsicum (Solanaceae) spp. Plants

“…Additionally, these results indicate that wild and landrace pepper populations differ in their level of A. eugenii resistance, and are more resistant than cultivated varieties of pepper under nochoice resistance tests. These results support previous studies indicating that cultivated species are less resistant to herbivores than wild and landrace populations (Garzón-Tiznado et al 2020;Millán-Chaidez et al 2020).…”

Population changes of Bemisia tabaci (Hemiptera: Aleyrodidae) on different colored poinsettia leaves with different trichome densities and chemical compositions

“…In this study, more eggs were found laid on green leaves than on red leaves of poinsettia, and leaf trichomes occurred at a far greater density on green leaves, nearly 10-fold that of red leaves. Previous studies found similar results, in that a high density of trichomes is favorable for whitefly reproduction in landrace, tomato, and cotton host plants (Acharya and Bhargava 2008, Firdaus et al 2012, Millan-Chaidez et al 2020, Pal et al 2021, Siddiqui et al 2021). That more eggs are laid where there are more trichomes could be due to the latter providing a favorable and safe microclimate for oviposition (Millan-Chaidez et al 2020).…”
