“…Several species of Lepidoptera use various cues related to plant quality to discriminate and select their host 32 . After landing, a short‐distance decision, chemoreceptors on antennae, mouthparts, and ovipositors are used to detect chemical cues 42 . The reduced oviposition of both pests, Bemisia tabaci and Tuta absoluta , might be a consequence of direct defense induction, related to the elevated level of the JA‐related gene observed in our study.…”

“…The reduced oviposition of both pests, Bemisia tabaci and Tuta absoluta , might be a consequence of direct defense induction, related to the elevated level of the JA‐related gene observed in our study. A high content of JA is linked to changes in arthropod feeding behavior, and the non‐volatile chemical compounds present on plant surfaces play a role in oviposition avoidance 33,42,43 …”

BACKGROUND Plant defenses activated by European zoophytophagous predators trigger behavioral responses in arthropods, benefiting pest management. However, repellence or attraction of pests and beneficial insects seems to be species‐specific. In the neotropical region, the mirid predator Macrolophus basicornis has proved to be a promising biological control agent of important tomato pests; nevertheless, the benefits of its phytophagous behavior have never been explored. Therefore, we investigated if M. basicornis phytophagy activates tomato plant defenses and the consequences for herbivores and natural enemies. RESULTS Regardless of the induction period of M. basicornis on tomato plants, Tuta absoluta females showed no preference for the odors emitted by induced or control plants. However, Tuta absoluta oviposited less on plants induced by M. basicornis for 72 h than on control plants. In contrast, induced plants repelled Bemisia tabaci females, and the number of eggs laid was reduced. Although females of Trichogramma pretiosum showed no preference between mirid‐induced or control plants, we observed high attraction of the parasitoid Encarsia inaron and conspecifics to plants induced by M. basicornis. While the mirid‐induced plants down‐regulated the expression of genes involving the salicylic acid (SA) pathway over time, the genes related to the jasmonic acid (JA) pathway were up‐regulated, increasing emissions of fatty‐acid derivatives and terpenes, which might have influenced the arthropods' host/prey choices. CONCLUSION Based on both the molecular and behavioral findings, our results indicated that in addition to predation, M. basicornis benefits tomato plant resistance indirectly through its phytophagy. This study is a starting point to pave the way for a novel and sustainable pest‐management strategy in the neotropical region. © 2022 Society of Chemical Industry.

“…Visual and chemical cue synergy has a behavior‐modifying effect in many insects (Raguso & Willis, ; Fukaya et al., ; Blackmer & Canas, ). For example, oviposition by the tomato fruit borer, Neoleucinodes elegantalis (Guenée), varies with the availability of visual (visibility of host) and chemical cues (hexane extract of tomato fruit) and the two cues have a synergistic effect on oviposition rates: tomato fruit borer laid more eggs when both visual and chemical cues were present together, compared to when either was presented separately or both were absent (Teles Pontes et al., ).…”

During oviposition, female insects utilize a wide variety of cues to find an optimal host for their offspring. These cues may be encountered simultaneously or sequentially, and females must rely on a hierarchical categorization to rank cues for optimal ovipositional choice. During alighting, cues are often encountered at different distances, which may influence hierarchical order. Cues that are observed at longer distances and are experienced first may be more influential on oviposition choice than those experienced at shorter distances. We tested the effects of two long‐distance cues, plant size and habitat structure, and two short‐distance cues, plant nitrogen level and predator presence, on Pieris rapae L. (Lepidoptera: Pieridae) oviposition choice through a series of two‐ and four‐choice tests in both greenhouse and field settings. We found that the long‐distance cues of plant size and habitat structure had the largest impact on P. rapae oviposition in laboratory and field settings, with females preferring large plants without habitat structure. Plant nitrogen level had a smaller impact on oviposition, and the presence of predators did not affect oviposition choice. However, plant size and plant nitrogen level had a synergistic relationship, with more eggs laid on large high‐nitrogen plants compared to large low‐nitrogen or small high‐nitrogen plants, suggesting that optimal cues throughout the entire searching process may be important for P. rapae in choosing a host plant.

“…Host plant acceptance by C. fraxinella probably integrates chemical cues from close‐range VOCs, contact chemoreception with mechanoreception, and visual signals, as occurs in other lepidopterans (Reed et al., ; Smallegange et al., ; Teles Pontes et al., ). Visual cues seem to be important for females to properly target leaflets.…”

Host plant preference and offspring performance of a leaf‐mining moth, Caloptilia fraxinella, on two Fraxinus species

The preference‐performance or ‘mother‐knows‐best’ hypothesis states that female insects choose to oviposit on a host plant that increases the performance of their offspring. This positive link between host plant choice and larval performance is especially important for leaf miners with non‐motile larvae that are entirely dependent upon the oviposition choice of the female for host plant location. Preference and performance of the ash leaf coneroller, Caloptilia fraxinella (Ely) (Lepidoptera: Gracillariidae), a specialist on ash trees, Fraxinus spp. (Oleaceae), were tested in a series of laboratory and field experiments. Female C. fraxinella were exposed to two closely related hosts, black ash, Fraxinus nigra Marshall, and green ash, Fraxinus pennsylvanica Marshall var. subintegerrima (Vahl), in oviposition choice and wind tunnel flight experiments to determine which host is most attractive for oviposition. Caloptilia fraxinella females were inconsistent in host choice, yet performance of larvae was greater on green than black ash. In preference studies, C. fraxinella preferred to oviposit on black ash when leaflets were removed from the tree, but preferred intact green ash over black ash seedlings for oviposition and host location in a wind tunnel. In the field, however, more C. fraxinella visited black ash var. ‘Fallgold’ at leaf flush than green ash at the same sites. Age of the ash leaflet also influences oviposition in this leaf miner and females preferred new over old leaflets for oviposition. Performance of C. fraxinella larvae was evaluated in field and laboratory experiments and was greater on green ash than on black ash in both experiments based on larval survival and development time parameters. The stronger oviposition and host location preference in the field for black ash were not linked to enhanced performance of offspring, as green ash was the superior host, supporting higher larval survival and faster development. A stronger host location preference in the wind tunnel for green ash over black ash, however, suggests that under certain circumstances with this moth species, ‘mother (may) know best’.
