Striga Management through Herbicide Resistance: A Public-Private Partnership in Action [PDF]

Striga is an indigenous parasitic weed that attacks cereals and other crops in Africa. In maize croplands alone, Striga infests over 2.3 million ha resulting in 1.6 million tons of grain loss worth US $383 million annually.

Studies on exploiting semiochemicals for pest management in organic farming systems OF0188 [PDF]

, 2000
This study addresses the extent to which pest management systems can exploit semiochemicals (defined below) in ways acceptable to organic farming, and determines where the science base needs to be expanded to accommodate specific problems arising in an ...

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 579-588, June 2026.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Influence of Alectra vogelii inoculation and phosphorus fertilizer application on phenology, yield components and grain yield of bambara groundnut genotypes

Heliyon
In sub-Saharan Africa, the parasitic Alectra vogelii is seriously threatening Bambara groundnuts, farmers to suffer yield losses of up to 100 %. The objective of this study was to determine the effects of phosphorus (P) application and Alectra vogelii ...

The significance of mycorrhizal fungi for crop productivity and ecosystem sustainability in organic farming systems [PDF]

, 2008
Mycorrhizal fungi are widespread in agricultural systems and are especially relevant for organic agriculture because they can act as natural fertilisers, enhancing plant yield.

Parasitic behavior of Amobia distorta (Diptera: Miltogramminae) and defensive behavior of its hosts, Anterhynchium spp. (Hymenoptera: Vespidae: Eumeninae)

Entomological Science, Volume 29, Issue 2, June 2026.
The parasitic behaviour of Amobia distorta and the defensive behaviour of its hosts, Anterhynchium flavomarginatum (native species) and A. gibbifrons (probably non‐native), were observed. Abstract Two Anterhynchium species, A. flavomarginatum and A. gibbifrons, are solitary tube‐renting eumenine wasps that occur sympatrically in Japan.

Induced defence by a root hemiparasite increases host plant resistance against future infection

Plant Biology, Volume 28, Issue 4, Page 1279-1288, June 2026.
Infection by root hemiparasites can increase mortality of parasites during future infection, indicating induced host defence mechanisms. Abstract European grassland plants are frequently attacked by root hemiparasites. However, little is known about host defence responses to parasitism.
