Striga seed-germination activity of root exudates and compounds present in stems of Striga host and nonhost (trap crop) plants is reduced due to root colonization by arbuscular mycorrhizal fungi. [PDF]

open access: yes, 2009
Root colonization by arbuscular mycorrhizal (AM) fungi reduces stimulation of seed germination of the plant parasite Striga (Orobanchaceae). This reduction can affect not only host plants for Striga, resulting in a lower parasite incidence, but also ...

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

open access: yesPest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Preliminary study for testing the significance of butyl–iso–butyl phthalate in ‎controlling faba bean broomrape [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2019
Due to deleterious impacts of broomrapes against the host plants, its combating is ‎essential for sustaining crop productivity. Thus, two–year field trail was conducted at ‎El Nubaria experimental farm, National Research Centre, Egypt, on two faba bean ...

CRISPR/Cas9-mediated mutagenesis of CAROTENOID CLEAVAGE DIOXYGENASE 8 in tomato provides resistance against the parasitic weed Phelipanche aegyptiaca. [PDF]

open access: yes, 2019
Broomrapes (Phelipanche aegyptiaca and Orobanche spp.) are obligate plant parasites that cause extreme damage to crop plants. The parasite seeds have strict requirements for germination, involving preconditioning and exposure to specific chemicals ...

Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

open access: yesPest Management Science, EarlyView.
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...

Populations of the Parasitic Plant Phelipanche ramosa Influence Their Seed Microbiota

open access: yesFrontiers in Plant Science, 2020
Seeds of the parasitic weed Phelipanche ramosa are well adapted to their hosts because they germinate and form haustorial structures to connect to roots in response to diverse host-derived molecular signals. P.

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

open access: yesPest 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.

Commercial permethrin elicits chemoreceptive responses on different Anopheles gambiae sensory appendages

open access: yesPest Management Science, EarlyView.
Anopheles gambiae mosquitoes exhibit takeoff responses when presented to commercial permethrin headspace. This product elicits electrophysiological activity in the antennae and tarsi. However, only the chemical information acquired from the tarsi plays a major role in the observed behavioral response.

Characterization resistance mechanisms in faba bean (Vicia faba) against broomrape species (Orobanche and Phelipanche spp.)

open access: yesFrontiers in Plant Science, 2016
Faba bean (Vicia faba) production in Mediterranean and Near East agriculture is severely constrained by broomrape infection. The most widely distributed broomrape species affecting faba bean is Orobanche crenata, although O.
