Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Host plant‐specific volatiles of Beauveria bassiana‐colonized plants initiate trophic plant–aphid–predator cascades

Pest Management Science, EarlyView.
Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Assessing the potential for insecticide cross‐resistance to a novel insecticide in the Colorado potato beetle (Leptinotarsa decemlineata) using phenotypic and transcript expression analysis

Pest Management Science, EarlyView.
Phenotypic and transcriptional responses to imidacloprid and isocycloseram were examined across U.S. populations of the Colorado potato beetle, showing evidence of phenotypic cross‐resistance alongside population‐level variation in detoxification gene expression.

Aphid Alarm Pheromone as a Cue for Ants to Locate Aphid Partners

PLoS ONE, 2012
The mutualistic relationships that occur between myrmecophilous aphids and ants are based on the rich food supply that honeydew represents for ants and on the protection they provide against aphid natural enemies. While aphid predators and parasitoids actively forage for oviposition sites by using aphid semiochemicals, scouts of aphid-tending ant ...

Soybean induced resistance to Spodoptera eridania herbivory

Pest Management Science, EarlyView.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Cannibalism in Buchananiella whitei (Hemiptera: Anthocoridae) and its intraguild interactions with seven predatory mites (Acari: Phytoseiidae & Laelapidae)

Pest Management Science, EarlyView.
Extraguild prey reduces cannibalism and intraguild predation in Buchananiella whitei, while first‐instar nymphs dominate most predatory mites, with outcomes affected by body size and behavioral traits. Abstract BACKGROUND Cannibalism and intraguild predation (IGP) are common interactions among predators that can influence the effectiveness of ...

Conifer-feeding aphids (Insecta: Hemiptera: Aphididae) of India, Bhutan and Nepal with descriptions of three new species of the genus Cinara

The European Zoological Journal, 2020
Here, we present a review of the conifer-feeding aphids of India, Bhutan and Nepal, which includes 30 species. Three new species, viz., Cinara (Cinara) bhutanica sp.

Endophytic fungi from two isolated Bethencourtia palmensis populations: metabolomic and bioactivity fingerprinting

Pest Management Science, EarlyView.
We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.
