“…The low insect pest occurrence across treatments during late planting is consistent with the hypothesis of this study, which strongly suggests a shift from the current planting date as farm-level adaptation to climate variability in the study area. This is commensurate with predictions on the [35] ecology of insect pests under climate change scenarios that combine experimental data and modeling of population dynamics [46]. The positive results for interaction of planting dates and treatments support the second hypothesis of this study, and represent a viable farm-level integrated pest management adaptation to current climate dynamics in the study area.…”

“…Values within rows with different letters are significantly different (P < 0.05) a Data taken from Tanyi et al [35] planting date as viable alternative farm-level adaptation to climate variability. These represent cost-effective and environmentally friendly pest management strategy that can be adopted by farmers to control cabbage pests below economic injury threshold and improve yield.…”

“…The organic Piper emulsion botanical comprised West African black pepper (Piper guineense) that was harvested from a primary forest at Inokun-Eyumojock in South-western Cameroon and prepared according to Tanyi et al [35]. Briefly, 250 g crushed sun-dried Piper seed powder was dissolved in 1 L vegetable oil (KING'S ® , Lagos-Nigeria) and 10 g detergent (SABA ® , Douala-Cameroon) was added to produce a sticky emulsion.…”

“…Values within rows with different letters are significantly different (P < 0.05) a Data taken from Tanyi et al [35] demonstrated efficacy as control measures for cabbage pests against the control, irrespective of the planting dates [18]. Tomato intercropping could be considered as the most affordable and cost-effective pest management strategy in relation to the other treatments.…”

Background: Considering the potential impact of climate change on the ecology of insect pests, different planting dates and cropping patterns were investigated as farm-level adaption to control insect pests of cabbage and improve productivity. Methods: This is a 3 × 4 factorial experiment setup in randomized complete block design including three planting dates (early, normal and late) and four cropping patterns (control-sole cabbage or tomato, tomato intercrop, Piper emulsion and insecticide) with four replications each. Results: Cabbage infestation ranged from 1 to 29 and correlated negatively with planting dates or treatments, which differed (P < 0.001) significantly across planting dates, treatments and their interaction, with the highest during early planting. Diamondback moth larvae correlated negatively with planting dates or treatments, ranging from 0 to 13 that differed significantly (P < 0.001) across planting dates, treatments and their interaction. Looper larvae correlated negatively with treatments, ranging from 0 to 8 that differed significantly (P < 0.001) across planting dates, treatments and their interaction, with highest during normal planting and lowest during late planting. Webworm larvae correlated negatively with planting dates or treatments, ranging from 0 to 13 that differed significantly (P < 0.001) across planting dates, treatments and their interaction. The number of sprouted plants ranged from 0 to 6 and differed significantly (P < 0.001) across planting dates, treatments and their interaction, with the highest in early planting for control that differed significantly from late planting. Cabbage yield correlated positively with planting dates and ranged from 2.8 to 6.0 tons per hectare that differed significantly (P < 0.001) across planting dates, treatments and their interaction, with the highest during normal and late planting dates. Conclusion: The interaction of planting dates and Piper emulsion or intercropping treatments can be effectively used as control measure for insect pests of cabbage leading to greater yield, with late planting as viable farm-level adaptation to climate variability.

African farmers are currently grappling with potential control measures for the invasive fall armyworm (FAW) (Spodoptera frugiperda), which has recently emerged as an important economic pest that is ravaging maize fields across the continent. We evaluated the efficacy of the West African black pepper extract and beans intercropping systems as viable FAW control measures and the implication on maize yields. The experiment comprised five treatments (control-no input, dwarf beans intercrop, climbing beans intercrop, West African black pepper extract, and insecticide) with three replications each. FAW severity was assessed at three to seven weeks after planting (WAP), while maize infestation was assessed at seven WAP. FAW severity increased significantly (P<0.05) across WAP for the control and dwarf beans intercrop, with the highest at four and six WAP, respectively. FAW severity also differed (P<0.05) significantly across treatments at four to seven WAP, with the lowest recorded in the extract of West African black pepper (Piper guineense) and the highest in control treatments. Maize infestation ranged from 13 to 93%, with the lowest in the West African black pepper extract and synthetic insecticide, followed by both dwarf and climbing beans intercrops and then the control. The maize yield determined at physiological maturity ranged from 2.2 to 6.3 t ha−1 across treatments and differed significantly, with the highest in the West African black pepper extract and synthetic insecticide, followed by both the dwarf and climbing beans intercrops, as compared to the control. Overall, the West African black pepper extract and beans push cropping systems demonstrated efficacy as viable sustainable alternative control measures for the invasive fall armyworm in maize fields.
