Pectin Remodeling and Involvement of AtPME3 in the Parasitic Plant–Plant Interaction, Phelipanche ramosa–Arabidospis thaliana

Plants
Phelipanche ramosa is a root parasitic plant fully dependent on host plants for nutrition and development. Upon germination, the parasitic seedling develops inside the infected roots a specific organ, the haustorium, thanks to the cell wall-degrading ...

The effect of Orobanche crenata infection severity in faba bean, field pea, and grass pea productivity.

Frontiers in Plant Science, 2016
Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West ...

The Importance of the Larval Parasitoid Actia interrupta (Diptera: Tachinidae) in Low Density Eastern Spruce Budworm Populations

Entomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

Evaluation of fungal isolates as possible biocontrol agents against Striga hermonthica

Journal of Crop Protection, 2014
Striga hermonthica is a parasitic weed which largely constrains maize and sorghum production in Western Kenya. The weed mostly invades small scale farms and depending on severity, it may cause damage ranging from 10% to complete crop failure thereby ...

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

Entomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 2. Methods to Improve Overwintering, Adult Emergence and Longevity

Entomologia Experimentalis et Applicata, EarlyView.
Successful rearing of Istocheta aldrichi, a tachinid parasitoid of invasive Japanese beetle, depended on conditions before, during, and after overwintering. Longer cold exposure increased adult emergence and accelerated post‐diapause development. Early transfer of puparia to cool conditions improved survival, while spring temperature manipulation ...

Understanding the present distribution of the parasitic weed Striga hermonthica and predicting its potential future geographic distribution in the light of climate change

Julius-Kühn-Archiv, 2012
Parasitic weeds of the genus Striga (Orobanchaceae) are a major constraint to agricultural production in the semi-arid regions in Sub-Saharan Africa. Therefore, Striga hermonthica’s current and future distribution needs to be estimated urgently in order ...

Recent research progress in combatting root parasitic weeds

Biotechnology & Biotechnological Equipment, 2018
The obligate root parasitic Orobanchaceae plants Striga, Orobanche and Phelipanche spp. parasitize economically important crops, vegetables and oil plants. They are the most devastating agricultural weed pests worldwide.

Physiological Host Range of the Tachinid Istocheta aldrichi, a Potential Biological Control Agent for the Japanese Beetle in Europe

Entomologia Experimentalis et Applicata, EarlyView.
This study provides the first laboratory assessment of the physiological host range of Istocheta aldrichi, a candidate biological control agent for Popillia japonica in Europe. In sequential no‐choice tests with 14 European scarab beetles, the parasitoid oviposited on six species but successfully developed only in the two Rutelinae Anomala vitis and ...

Life‐History Traits and Overwintering of Actia interrupta (Diptera: Tachinidae), a Larval Parasitoid of Choristoneura fumiferana (Lepidoptera: Tortricidae)

Entomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.
