Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Influence of urbanisation and plants on the diversity and abundance of aphids and their ladybird and hoverfly predators in domestic gardens

European Journal of Entomology, 2018
Urban gardens can harbour a high diversity of insects, which are critically important components of urban ecosystems. In this work, we investigate the richness and diversity of a major taxon of economic and ecological importance, the aphids (Hemiptera ...

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

Entomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Emerging experimental and bioinformatic approaches in RNA interference‐based pest control research

Insect Molecular Biology, EarlyView.
Double‐stranded RNA (dsRNA) visualization, RNA‐induced silencing complex (RISC)‐bound sRNA‐seq and RNA degradomics allow investigating dsRNA uptake and processing, guide small interfering RNA selection and RISC‐mediated target mRNA cleavages. Transcriptomic and proteomic profiles of genome‐wide responses to dsRNA, including off‐target and compensatory ...

Three Decades of China's Bt Cotton: Achievements and Insights

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.

The evolution of chemical defenses along invasion routes: Harmonia axyridis Pallas (Coccinellidae: Coleoptera) as a case study

Ecology and Evolution, 2018
The evolution of increased competitive ability (EICA) hypothesis (Blossey & Nötzold, ) postulates that escaping from coevolved enemies increases invaders fitness by energy reallocation from defenses and immunity to growth and reproduction.

Unconditioned and conditioned responses to colour in the predatory coccinellid, Harmonia axyridis (Coleoptera: Coccinellidae)

European Journal of Entomology, 2000
We determined if mature ladybirds use colour to initially find suitable host plants. We also determined whether ladybird beetles are capable of associating characteristics such as colour with the presence of prey.

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Effect of presence and semiochemicals of conspecific stages on oviposition by ladybirds (Coleoptera: Coccinellidae)

, 2012
Reduced oviposition by ladybirds in the presence of tracks of fourth instar larvae owing to the presence of oviposition deterring pheromones is well established across many genera.

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

Plant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.
