Endophytic colonization by Beauveria bassiana increases the resistance of tomatoes against Bemisia tabaci Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-03-04 Qiu-Yang Wei; Ya-Ying Li; Chen Xu; Yi-Xia Wu; Ya-Ru Zhang; Huai Liu
Beauveria bassiana, an entomopathogenic fungus, can exist asymptomatically as an endophyte in many plants. This study aimed to determine the efficiency of B. bassiana colonization of tomato plants using different inoculation methods, and how colonization of the host plant affects the key pest of tomato, the whitefly Bemisia tabaci. To confirm fungal colonization efficiency, nested PCR technique was

Arbuscular mycorrhizal fungi (AMF) influences growth and insect community dynamics in Sorghum-sudangrass ( Sorghum x drummondii ) Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-02-27 Jasleen Kaur; Jesus Chavana; Pushpa Soti; Alexis Racelis; Rupesh Kariyat
Beneficial plant–microbe interactions in the rhizosphere have been found to enhance plant growth and development. Arbuscular mycorrhizal fungi (AMF), a major group among these microbes, have been found to improve plant fitness through mycorrhizal symbiosis. Despite being well documented in various natural and domesticated study systems, few studies have examined whether AMF also has cascading effects

How high are the costs inflicted by an herbivorous pollinator? Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-27 Andrew C. McCall; Goggy Davidowitz; Judith L. Bronstein
Many adult Lepidoptera nectar at flowers of plant species on which they also deposit their eggs. As a consequence, the same partner may act as both a pollinator and herbivore. How high are the costs associated with such herbivorous pollinators, relative to the potential benefits they confer? We addressed this question in the association between Datura wrightii (Solanaceae) and Manduca sexta (Sphingidae)

Evaluation of preference of brown marmorated stink bug, Halyomorpha halys (Stål) for different colour bell peppers and the role of plant protein Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-25 Melvin Mensah-Bonsu; Beatrice N. Dingha; Louis E. N. Jackai; Sarah Adjei-Fremah; Mulumebet Worku
The brown marmorated stink bug (BMSB), Halyomorpha halys, (Stål) (Hemiptera: Pentatomidae) a highly polyphagous invasive pest from Asia, has become a major agricultural pest in the United States. Laboratory experiments were conducted to determine nymph and adult BMSB preference for bell peppers of different colours (red, yellow, green, and orange). Peppers were presented to BMSB using a Dual Choice

How bottom-up effects of different tomato cultivars affect population responses of Tuta absoluta (Lep.: Gelechiidae): a case study on host plant resistance Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-24 Nasrin Heidari; Amin Sedaratian-Jahromi; Mojtaba Ghane-Jahromi; Myron P. Zalucki
The Gellechiid moth, Tuta absoluta (Meyrick), causes severe problems in many tomato-growing regions worldwide. The present study investigated bottom-up effects under laboratory conditions (25 ± 1 °C, 65 ± 5% R.H., and 16 h L.P.) of six commercial tomato cultivars (‘Rio grand’, ‘Atrak’, ‘Super strain B’, ‘Unigen’, ‘King ston’, and ‘Estern’) on biological traits of this pest. The results obtained evaluated

Neuroactive nectar: compounds in nectar that interact with neurons Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-14 Julie A. Mustard
As well as sugars to entice pollinators, nectar contains many other chemicals including amino acids and plant secondary compounds such as phenolics, alkaloids, and glycosides. Rather than simply the byproducts of plant metabolism or contamination by compounds meant to deter herbivory, it is clear that these chemicals may have important roles in nectar. Proposed functions of non-sugar components of

Changes in pollinator community of Scadoxus cinnabarinus (Amaryllidaceae) along its elevational range on Mount Cameroon Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-13 Jan E. J. Mertens; Štěpán Janeček; Fairo F. Dzekashu; Eliška Chmelová; Eric B. Fokam; Robert Tropek
The pollination syndrome hypothesis has been under debate over the past decades. It is criticized as an oversimplification of complex interactions: its validity varies across plant families and depends on spatio-temporal variability of plant–pollinator interactions, yet exact patterns are unclear. We tested the pollination syndrome predictability in a case study of a psychophilous Afrotropical herb

Leaf herbivory modulates fruit trait correlations within individual plants Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-13 Mariana Valoy; Juan Carlos López-Acosta; Silvia Lomáscolo; Facundo Bernacki; Omar Varela; Mariano Ordano
Plant performance is based on the relationship between resource acquisition and allocation to complete essential functions. Herbivory causes compromises in resource allocation that impact at the plant and within-plant (sub-individual) levels. This impacts fruit display traits which in turn affect reproductive success and seed dispersal. Because leaf damage affects resource allocation, herbivory should

Floral temperature patterns can function as floral guides Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-13 Michael J. M. Harrap; Natalie Hempel de Ibarra; Heather M. Whitney; Sean A. Rands
Floral guides are signal patterns that lead pollinators to floral rewards after they have located the flower, and increase foraging efficiency and pollen transfer. Patterns of several floral signalling modalities, particularly colour patterns, have been identified as being able to function as floral guides. Floral temperature frequently shows patterns that can be used by bumblebees for locating and

The cotton bollworm endoparasitoid Campoletis chlorideae is attracted by cis -jasmone or cis -3-hexenyl acetate but not by their mixtures Arthropod Plant Interact. (IF 1.466) Pub Date : 2020-01-02 Ya-Lan Sun; Jun-Feng Dong; Ling-Qiao Huang; Chen-Zhu Wang
Campoletis chlorideae Uchida (Hymenoptera: Ichneumonidae) is an important larval endoparasitoid of the cotton bollworm Helicoverpa armigera (Hübner). A better understanding of herbivore-induced plant volatiles (HIPVs) employed by C. chlorideae to locate hosts will contribute towards the biological control of this notorious crop pest. In this study, we first investigated the electrophysiological and
