To address this need, the present study deciphered variation in phenological traits and photosynthetic pigment levels in maize lines and their effect on the biological attributes of <i>S. frugiperda</i>. The study revealed significant differences among the test maize lines for phenological traits, constitutive and insect-induced photosynthetic pigments, and biological attributes of <i>S. frugiperda</i>.

The larval preference and leaf damage by <i>S. frugiperda</i> was significantly lower in A-lines AI 546, AI 544, and PDIM 639, and R-lines AI 125, AI 542, AI 155, AI 1100, and CML 442. Further, the <i>S. frugiperda</i> developmental durations and life span were longer, while larval survival, adult emergence and fecundity lower on the A-lines CML 565, AI 544, AI 196, and PDIM 639, and R-lines AI 125, AI 155, AI 1100, AI 542, and CML 442 in comparison to other test lines, except in a few cases.

In this field study, we investigated how drought stress alters plant and flower traits of faba beans and the resulting pollinator behavior in faba bean sole crops and in faba bean–wheat intercrops. Plant height was reduced by drought stress and in intercrops (vs. sole crops). The number of open flowers per plant was unaffected by drought stress but reduced in intercrops. Drought stress increased the nectar sugar concentration but did not alter nectar volume and pollen production. Faba beans grown in intercrops produced higher nectar, sugar, and pollen grain amounts compared to sole crops. Drought stress effects on plant and flower traits were not affected by intercropping. Drought stress reduced the plant and flower visitation frequency by bumblebees. Although intercropping plots were visited less frequently, the individual flowers were visited more frequently than flowers in sole crops. The bumblebees’ nectar robbing activity increased with plant height and flower sugar amount. Our study shows that drought stress reduces crop plant growth and reduces pollinator visitation to crop flowers. Faba bean flowers in intercrops seem to be more attractive to bumblebees than flowers in sole crops, potentially enhancing pollination.

This study examined the hypothesis that herbivory of <i>E. annulipes</i> on various species of cultivated <i>Brassica</i> has a positive effect on its biological traits and is influenced by the availability of essential food sources. The provisioned plant material (pieces of leaf) consisted of the following <i>Brassica</i> species: pak choi cabbage, Portuguese cabbage, cabbage, and radish did not improve the biological performance of the earwig when compared to a diet without plant material. Nevertheless, 66.0% of the second instar nymphs developed successfully when fed only pak choi cabbage, and 43.3% did so when fed solely on Portuguese cabbage. Herbivory by <i>E. annulipes</i> on brassicas occurred in the presence and absence of a diet, although it was significantly more pronounced when no other food sources were available. Among the four <i>Brassica</i> species studied, pak choi cabbage exhibited the highest feeding frequency and consumption rate. Additionally, pak choi cabbage grown under controlled conditions and exposed to routine releases of earwigs showed no reduction in productivity. These findings indicate that <i>E. annulipes</i> can consume brassica leaves, demonstrating species-specific variations in this consumption. However, conditions of food scarcity lead to increased consumption of plant material, while repeated releases of earwigs do not affect the growth and yield of pak choi cabbage plants.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"19 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the effect of agricultural practices on the development of trichomes and their importance in the defense of tomato plants against insect herbivores, specifically the pest <i>Zonocerus variegatus</i>. A survey was conducted in two major tomato production areas in Southern Benin, presenting different agricultural practices that could influence the development of trichomes. Samples from 200 tomato plants were collected from various tomato fields and trichomes on leaf and stem samples were counted using an optical microscope. Additionally, to understand the responses of specific tomato varieties to attacks by insect herbivores, experiments were conducted on the varieties Akikon, Tounvi, and Thorgal cultivated in pots and then subjected to biotic stress by <i>Z. variegatus,</i> with both control and experimental batches. Three weeks later, leaf and stem samples were taken and the trichomes were observed and also counted. Subsequently, phytochemical screenings and quantification of secondary metabolites were performed on the experimental and control plants. Structural Equation Models analysis revealed a significant positive effect of cropping systems and fertilization methods on trichome density, but a significant negative effect of soil type and biopesticide use. The experiment results showed an increase in trichome density in response to pest attacks. Phytochemical screenings revealed considerable production of polyphenols and flavonoids in all three varieties. The rate of insect damage was highest in the Tounvi tomato variety, followed by the Akikon variety and finally the Thorgal variety which released more flavonoids and polyphenols. These findings underscore the vital function of trichomes in protecting tomato plants against herbivore insects. This study provides a theoretical and practical basis for advancing and integrating the roles of trichomes in controlling insect herbivores and improve tomato production.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"19 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ants can benefit plants by preying on pests, but when they interact with honeydew-producing pests and start to defend these pests (e.g., attacking natural enemies), ants may become detrimental.
