“…A plant's allelochemicals may influence, directly and indirectly, a predator's performancedirectly, through the presence of physical structures such as trichomes exuding chemicals (Bottega et al, 2017) or through the uptake of nutrients and water from the plant (De Clercq & Degheele, 1992;Wiedenmann et al, 1996;De Clercq et al, 2000), or indirectly, through their prey, which may sequester these plant compounds and use them against natural enemies (Weiser & Stamp, 1998;Chaplin-Kramer et al, 2011;Reudler et al, 2015). Once ingested by herbivorous insects, a sequestered substance may be reabsorbed by the intestinal membrane, transported to the hemolymph, and deposited in various body parts, becoming toxic or unpalatable to its natural enemies (Nishida, 2002).…”

Many herbivorous insects can overcome chemical plant defenses, using the plant's defensive products for their own good, as a defense against predators. Eucalyptus spp. (Myrtaceae), recently introduced in Brazil, are rich in secondary compounds; however, there are reports that these plants have been suffering from population outbreaks of defoliating Lepidoptera in Brazil. The predator Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) has been used against herbivorous insects in eucalyptus plantations, but little is known about its establishment in the field. This study aims to investigate whether the effectiveness of this predator may be affected indirectly by compounds of eucalyptus plants, when compared to guava, Psidium guajava L., a Brazilian native species of Myrtaceae. Thus, we evaluated the performance of P. nigrispinus on larvae of Thyrinteina arnobia (Stoll) (Lepidoptera: Geometridae) reared on eucalyptus (exotic species) or guava plants (native species). Podisus nigrispinus performance (reproduction and survival) was better on larvae fed on guava than on larvae fed on eucalyptus. It is possible that the negative effect on the predator's development occurred because of the plants’ secondary compounds appropriated by caterpillars, due to the short coevolutionary history between eucalyptus and the predator. The data suggest that the chemical compounds that could help the plant's defenses against herbivores may also affect their natural enemies, especially when the interaction between plant and natural enemy involves an exotic plant recently introduced into the insect's habitat.

“…George and Lapointe 31 suggested that morphological and physiological barriers associated with access to the phloem sieve elements, poor nutritional quality, and deterrent chemical compounds may be involved in P. trifoliata resistance to D. citri . Trichome density is a morphological trait that may serve as a defense against insect herbivory 33–36 thereby interfering with insects landing, walking, and feeding on plant surfaces 37,38 . In Citrus and Poncirus , trichomes have little to no role in deterring oviposition by D. citri 39 .…”

BACKGROUND Host genetic resistance is a promising strategy for the management of Diaphorina citri Kuwayama (Hemiptera: Psyllidae), and consequently Huanglongbing (HLB). To date, no study has investigated the resistance to D. citri in the clonal and vegetatively propagated plants of the Microcitrus, Eremocitrus, and Atalantia genera. This study assesses Near and True Citrus genotype antixenosis and antibiosis against D. citri, with trichome density and volatile emission as possible mechanisms of resistance. RESULTS All genotypes were oviposited by D. citri, however, 8 of 14 genotypes were less oviposited than Citrus × sinensis ‘Valencia’ (susceptible control). Diaphorina citri nymphs had lower nymphal viability in E. glauca (31%) and M. warburgiana (58%) than that in Citrus × sinensis (77%). The behavioral assay showed that 30% of D. citri nymphs in the last instars evaded E. glauca shoots, whereas no nymphs evaded Citrus × sinensis shoots. A higher trichome density was observed in E. glauca shoots compared to the other genotypes. Chemical analysis revealed differences in the volatile profiles of E. glauca and Citrus × sinensis. CONCLUSION Eremocitrus glauca and M. warburgiana genotypes were more resistant to D. citri than Citrus × sinensis. Higher trichome density in the shoots may negatively influence the development of D. citri nymphs. Eremocitrus glauca volatiles may also be involved in their resistance to D. citri. © 2022 Society of Chemical Industry.
