Genetics of Resistance to Striga and Alectra in Cowpea

Journal of Heredity, 1995
The parasitic weeds Striga gesnerioides (Willd.) Vatke and Alectra vogelli (Benth.) cause considerable demage to cowpea [ Vigna unguiculata (L.) Walp] in the semiarid regions of Africa. Systematic screening has revealed few cowpea varieties to be resistant.

Independent Inheritance of Striga and Alectra Resistance in Cowpea Genotype B301 [PDF]

Crop Science, 1993
Cowpea [Vigna unguiculata (L.) Walp] is a major food legume the semi‐arid region of Sub‐Saharan Africa. Recently, two parasitic weeds, Striga [Striga gesnerioides (Willd.) Vatke] and alectra [Alectra vogelii Benth.] have become a major threat to cowpea cultivation in this region.

Increasing the diversity of Sycorax Haliday, 1839 (Diptera: Psychodidae) in the Neotropical region: New species from the Brazilian Atlantic Forest

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract Four new species of Sycorax Haliday, 1839 are described: Sycorax alumna sp. nov., Sycorax catarina sp. nov., Sycorax paranaensis sp. nov., and Sycorax striga sp. nov., with the females of Sycorax striga sp. nov. bearing characteristics that suggest haematophagous behaviour.

Gains in Genetic Enhancement of Early Maturing Maize Hybrids Developed during Three Breeding Periods under Striga-Infested and Striga-Free Environments

Agronomy, 2020
Striga hermonthica is a major maize production constraint in West and Central Africa (WCA). Fifty-four early maturing maize hybrids of three breeding periods: 2008–2011, 2012–2013, 2014–2015, were evaluated under Striga-infested and non-infested ...

Inheritance of Resistance to Striga in Sorghum Genotype SRN39 [PDF]

Plant Breeding, 1992
Abstract Striga hermonthica (Del.) Benth., a parasitic weed of grasses, causes major yield reductions in the principal cereal crops of semi‐arid Africa. Cultivar resistance is the most economic control measure, since adapted, resistant cultivars can be grown without additional input from the subsistence farmer. Information on the genetics of resistance
