Observation Carpolobia spp. had a random distribution.
Observation Irvingia gabonensis had a random distribution.
Observation Gnetum spp. had a random distribution limited to central and southern areas.
Observation R. heudelotii had a clumped distribution across northern, central and southern park areas.
Association Footpaths affected NTFP distribution.
Association Farmland affected NTFP distribution.
Association Local timber exploitation affected NTFP distribution.
Mechanism Whole-plant harvest pressure was high for Carpolobia spp. and reduced regeneration capacity.
Mechanism Whole-plant harvest pressure was high for Garcina mannii and reduced regeneration capacity.
Recommendation Distribution, availability and recruitment information could aid conservation education and enforcement.

Title

Extracts of tropical African spices are active against Plutella xylostella

Nelson Neba Ntonifor; I. Mueller‐Harvey; R. H. Brown CentAUR (University of Reading) 2010

Other claims from this paper (14)

Intervention effect Water and ethanol extracts of Piper guineense were dose-dependent antifeedants at 300 ppm and 500 ppm respectively.
Intervention effect Methanol extracts of Piper guineense required at least 1,000 ppm to act as antifeedants.
Intervention effect Methanol and hexane extracts of Aframomum melegueta acted as antifeedants at 100 ppm.
Intervention effect Water extracts of Aframomum melegueta acted as antifeedants at 300 ppm.
Intervention effect Ethanol extracts of Aframomum melegueta were only slightly deterring feeding at 1,000 ppm.
Intervention effect Hexane and methanol extracts of Aframomum citratum inhibited feeding at 300 ppm.
Intervention effect Water extracts of Aframomum citratum inhibited feeding at 500 ppm.
Intervention effect No mortality of Plutella xylostella larvae was observed at any tested concentration after topical application of the extracts.
Association The effects of the extracts on larval development varied with extract concentration and larval age.
Intervention effect Ingestion of water and ethanol extracts of Piper guineense caused 100% mortality of second instars at 100 ppm two to three days after infestation.
Association Mortality of third instars was significantly lower than that of second instars.
Intervention effect Water or ethanol extracts of Piper guineense caused 100% mortality of third instars two to four days after infestation.
Intervention effect Larvae surviving to pupation had significantly longer larval periods than the control after application of Aframomum melegueta extracts.
Recommendation The authors recommend potent extracts of Aframomum melegueta, Aframomum citratum and especially Piper guineense as complementary measures against Plutella xylostella by subsistence farmers.
