Foreword

Foliar behaviour of biogenic semi-volatiles: potential applications in sustainable pest management

Plants emit an extremely diverse bouquet of volatile organic compounds (VOCs) from their above-ground and below-ground parts. Emissions are constitutive or induced, e.g. by herbivores. VOCs can be classified as highly volatile, volatile and semi-volatile compounds. Sesquiterpenes (SQTs) are typical semi-volatile organic compounds (sVOCs) released by plants. Similarly, herbivore...

The effects of rainfall on plant–pollinator interactions

As global surface temperatures rise, global precipitation rates are predicted to increase. These localised increases in rainfall patterns may significantly affect plant–pollinator interactions in multiple ways. Detrimental effects to plant–pollinator interactions could have significant ecological and economic consequences, and so it is important to understand the effects that...

Responses of ground-dwelling spider assemblages to changes in vegetation from wet oligotrophic habitats of Western France

While many arthropod species are known to depend, directly or indirectly, on certain plant species or communities, it remains unclear to what extent vegetation shapes spider assemblages. In this study, we tested whether the activity-density, composition, and diversity of ground-dwelling spiders were driven by changes in vegetation structure. Field sampling was conducted using...

Arthropod infestation sites and induced defence can be traced by emission from single spruce needles

Emissions of defence chemicals from Norway spruce seedlings can be induced by feeding arthropods or by exogenous hormonal application. Some defence chemicals may attract or repel associated arthropods. The aim of this study was to show that it is possible to detect and collect stress-induced volatiles from micro sites, such as at the scale of a single needle, in vivo by using...

Developing ecostacking techniques for pollen beetle management in oilseed rape

In this review, we examine how the principles of ecostacking could be used to manage the pollen beetle Brassicogethes aeneus in oilseed crucifer crops. We further describe hindrances preventing progress of keeping the pest under full biological control across Europe, and for other similar pest management situations. Ecological processes at different levels need to be considered...

The effect of plant development on thrips resistance in Capsicum

Western flower thrips [Frankliniella occidentalis (Pergande)] is a worldwide pest insect that causes damage in pepper cultivation, so growers would benefit from host plant resistance. The objectives of this study were (1) to evaluate the effect of plant age on thrips resistance using nine Capsicum accessions with different levels of thrips resistance at three different plant ages...

Genetic variation in phytochemicals in leaves of pepper (Capsicum) in relation to thrips resistance

Phytochemicals not only determine the taste and smell of plants and their products, they also play a crucial role in resistance against pests and pathogens. In previous work, we identified a form of resistance to thrips (Frankliniella occidentalis) expressed in leaves of pepper (Capsicum annuum). In the current study, we characterized leaves of an interspecific C. annuum × C...

The phytopathogen powdery mildew affects food-searching behavior and survival of Coccinella septempunctata

The diet of entomophagous coccinellids is mainly based on aphids and other food sources such as pollen, nectar, or fungal spores. Knowledge of their foraging behavior on plants infected by powdery mildew and their survival on fungal spores is currently limited. In this study, we investigated the olfactory response of Coccinella septempunctata to odor emission of barley plants...

Gene expression of serine and cysteine proteinase inhibitors during cereal leaf beetle larvae feeding on wheat: the role of insect-associated microorganisms

Plants and insects have been coexisting for more than 350 million years. During this time, both have evolved many strategies to successfully exploit or respond to reciprocal adaptation and defense reactions. Plants tend to minimize the damage caused by pest feeding, while pests tend to manipulate plant response by suppressing plant defense mechanisms or developing strategies to...

Prospects for improved off-crop habitat management for pollen beetle control in oilseed rape

There is an urgent need to develop sustainable and environmentally benign integrated pest management (IPM) strategies for arable crops. The enhancement and manipulation of naturally occurring populations of the natural enemies of crop pests through habitat management for ‘conservation biological control’, as well as habitat management to manipulate populations of the pests...

The potential of crop management practices to reduce pollen beetle damage in oilseed rape

A major problem associated with agricultural intensification over recent decades has been the development of insecticide resistance in crop pest populations. This has been a particular issue for control of the pollen beetle (Brassicogethes aeneus syn. Meligethes aeneus), a major pest of oilseed rape throughout Europe. Sustained and often prophylactic use of pyrethroid...

Semiochemical-based alternatives to synthetic toxicant insecticides for pollen beetle management

There is an urgent need to develop sustainable pest management systems to protect arable crops in order to replace the current over-reliance on synthetic insecticides. Semiochemicals are insect- or plant-derived chemicals that are used by organisms as information signals. Integrated pest management tools are currently in development that utilise semiochemicals to manipulate the...

Struggle to survive: aphid—plant relationships under low-light stress. A case of Acyrthosiphon pisum (Harris) and Pisum sativum L.

Light is primary source of energy and also plays signaling and regulatory roles in developmental processes and defense responses of plants. The aim of the study was to determine the performance, settling preferences, probing, and feeding behavior of Acyrthosiphon pisum on Pisum sativum grown in complete darkness (NL), with light at minimum level required for photoperiodic...

The effect of co-infestation by conspecific and heterospecific aphids on the feeding behaviour of Nasonovia ribisnigri on resistant and susceptible lettuce cultivars

Aphid saliva can suppress the blocking of sieve elements, a reaction that plants employ to inhibit aphid feeding, but aphid saliva can also elicit plant defence responses. Such plant responses might affect interactions between different aphid species and intraspecifically, e.g. among different biotypes. The objectives of our study were to investigate if feeding behaviour and...

Insights from measuring pollen deposition: quantifying the pre-eminence of bees as flower visitors and effective pollinators

Using our accumulated datasets from Kenyan savanna, Mediterranean garigue, UK gardens and heathland, involving 76 plants from 30 families, we present detailed data to quantify the superiority of bees as pollinators of most flowering plants when compared with other flower visitors. Bees provided the majority of visits to study species at all sites, and 33 of the 76 plants received...

A dual function for 4-methoxybenzaldehyde in Petasites fragrans? Pollinator-attractant and ant-repellent

Ant-repellent floral volatiles offer one method through which plants can mediate the detrimental effects of ants on flowers. Although the repellence itself is well documented, the volatiles involved are less well explored. Here, we investigated the floral bouquet of ant-repellent male flowers of Petasites fragrans, identifying 4-methoxybenzaldehyde as the main component. 4...

Pollen and stamen mimicry: the alpine flora as a case study

Many melittophilous flowers display yellow and UV-absorbing floral guides that resemble the most common colour of pollen and anthers. The yellow coloured anthers and pollen and the similarly coloured flower guides are described as key features of a pollen and stamen mimicry system. In this study, we investigated the entire angiosperm flora of the Alps with regard to visually...

Accumulation of amino acids and phenolic compounds in biochemical plant responses to feeding of two different herbivorous arthropod pests

The study aimed at comparing the changes in the content of free amino acids, phenolic compounds and the activity of PAL and TAL caused by two piercing-sucking arthropods: the grape mealybug (Pseudococcus maritimus Ehrh.) and the two-spotted spider mite (Tetranychus urticae Koch) in the leaves of orchid and strawberry, respectively. The obtained results show that the amino acid...

Interpopulation variation in pollinators and floral scent of the lady’s-slipper orchid Cypripedium calceolus L.

Floral scent is a key mediator in many plant–pollinator interactions. It is known to vary not only among plant species, but also within species among populations. However, there is a big gap in our knowledge of whether such variability is the result of divergent selective pressures exerted by a variable pollinator climate or alternative scenarios (e.g., genetic drift...
