This paper emphasizes the need for a crop breeding approach to increase the market availability of crop varieties/species needed for crop diversification rather than focusing on breeding for dominant crops.

Incorporating a trifluoromethyl pyridine ring into research programs has successfully identified useful agrochemicals. We describe approaches used, with selected examples to illustrate the impact on physico-chemical properties and biological activity.

Easy and cheap production, efficient delivery, bioinformatics for biosafety and selectivity in design of dsRNA. Control of pest insects, mites, ticks, plant pathogenic fungi, root-knot nematodes, weeds and viruses.

In modern agriculture, the digitalization of the production processes increases. The usage of new technologies makes the production of field crops more precise, efficient, sustainable and faster in reaction. This article presents trial results of using camera sensors to apply Fungicides site-specific over the field.

Differences in response to oversupply of pheromone were observed in four insect orders, with only moths showing evidence of habituation, with implications for behavioural control for non-moth pests.

CYP6FU1 is capable of metabolizing deltamethrin. This finding confirms its function in deltamethrin resistance and provides a better understanding of the resistance mechanism in L. striatellus. CYP6FU1 preferentially metabolizes p-nitroanisole with high activity, and might be a potential diagnostic probe for deltamethrin metabolic resistance detection and monitoring.

Pesticides may provide stimuli for species dispersal, which may also occur for passive dispersal, a possibility that is frequently neglected. Here, we report pesticide-induced passive dispersal in the predatory mite Neoseiulus baraki.

Resistance to diflufenican in oriental mustard is confirmed as being attributable to the Leu-526-Val mutation in phytoene desaturase. The inheritance of resistance is conferred by a highly dominant single gene.

The feeding activity of the zoophytophagous mirid predators N. tenuis and M. pygmaeus has been shown to induce defensive responses in sweet pepper plants for the first time.

This first report of R81T from North Africa reflects a continuing expansion of its range around the Mediterranean Basin. Loss of efficacy of neonicotinoids presents a serious threat to the sustainability of aphid control.

We evaluated community-based integrated pest management (IPM) programs for reducing bed bug infestations. IPM programs were more effective in reducing bed bug infestations than traditional pest control services.

The acute toxicity of spinosad in adult workers affected walking behavior and caused disorganization of the midgut and Malpighian tubule epithelia.

The study reports the first evidence of resistance to pyrethroids in Italian Ae. albopictus populations, stressing the need to monitor insecticide resistance spread in order to maintain the effectiveness of insecticides.

This article demonstrates the extraordinary resistance of Berkshire rats to difenacoum and the presence of a metabolic component underlying this hyper-resistance in addition to the mutation of Vkorc1 gene.

Short- and long-term conditioning improved thermal plasticity in C. partellus and C. flavipes, with the host showing a higher level of plasticity than the parasitoid. The results have implications for synchronization of host–parasitoid phenology and the efficacy of biocontrol under conditions of global change.

Untilled fields hosted more voles but no-tillage management is more profitable for a positive environmental effect.

This article presents results demonstrating significant effects of azadirachtins on both larval and adult life stages of Asian long-horned beetle, an invasive insect pest of deciduous forests in North America.

There is a continuous search for novel natural compounds with insecticidal activity. This article describes the purification of a protease inhibitor and its potential to control Aedes aegypti larvae.

Catering to the growing demand for less toxic and more environmentally friendly insecticides, this study investigates the insecticidal effect of inert materials on the pharaoh ant, a notorious domestic pest.

Knockdown of CYP6BG1 reduced the total P450 activity and increased the chlorantraniliprole toxicity to P. xylostella; overexpression of CYP6BG1 in D. melanogaster decreased the insecticide toxicity to the flies.

Over one hundred steroid-like compounds were screened for possible 20E antagonists. Cucurbitacin B acts a potential insect growth regulator by antagonizing 20E activity and thus blocking 20E-induced molting and metamorphosis.

This article reveals that recently-derived weedy rice, an agricultural weed worldwide, can have wild traits but retain important cultivar features with lower genetic diversity than long-established weedy rice populations.

C. suppressalis has presented resistance issues to chlorantraniliprole. This article gives a comprehensive analysis on the biochemical and target levels to interpret the chlorantraniliprole resistance mechanism in both laboratory and field strains.

Changes in plasma butyrylcholinesterase activity in humanized-liver chimeric mice clearly reflected the exposure levels to organophosphate and carbamate pesticides. This article assesses the usefulness of chimeric mice for pesticide science.

This is the first report of a kdr mutation in Ae. albopictus in India and highlights the need for intensive research on unexplored target site mutations contributing to pyrethroid resistance.

The autosomal incompletely recessive resistance and fitness costs of S. frugiperda to spinosad can be exploited in insect resistance management strategies to preserve the lifetime of spinosad to control S. frugiperda.

A soybean seed coat chitinase was identified by mass spectrometry analysis and at 0.1% in artificial cotyledons reduced larval survival by 77%. FITC-labeled chitinase was detected in the gut and feces of larvae and when added to artificial seed coats caused larval mortality of 90%.

Rhopalosiphum padi is a destructive insect pest of wheat crops worldwide. This article presents the mechanisms of resistance of the pest to imidacloprid at biochemical and molecular levels.

The presence of Drosophila melanogaster results in a reduction of egg laying and emergence of Drosophila suzukii. We disuss this mechanism and the possibiliy of future pest control.

This article presents a important amino acid of FgCYP51B, Tyrosine 137. It could lead to resistance to tebuconazole when mutated to histidine and forms part of the TEC binding pocket.

The tolerance for household insects drive a person's control behaviour. This article presents relevant factors that drive tolerance levels, information-seeking behaviour and behavioural intent regarding household pest management.

Application of semiochemicals to increase the efficacy of weed biological control has not been reported. This article demonstrates semiochemicals can enhance weed biological control.

Control of plant commodities at points of entry is a first-line defense against pest invasions. We present an identification system for insect pests enabling rapid genetic on-site testing within 1 h.

The results of our study may prove useful for assessing environmental factors linked to the distributions of Trichogramma ostriniae and its lepidopteran hosts and identifying areas suitable for inundative releases.

A high level of resistance to 2,4-D was identified in two oriental mustard populations (P2 and P13). This article confirms that a reduction of 2,4-D translocation is likely the main cause of 2,4-D resistance and the inheritance of resistance is managed by a single gene with a high level of dominance in oriental mustard.
