“…However, only a few pests and diseases were identified in Guinea-Bissau (Table 1), with no reports on the impact on cashew productivity. Pests that were widely reported in other West African countries as causing significant losses in cashew production [21] could also be identified in Guinea-Bissau (e.g., Apate terebrans Pallas, Analeptes trifasciata Fabricius) [25]. For instance, the trunk and root borer-Plocaederus ferrugineus L.-which is considered a pest of increasing importance in Nigeria [26], was recorded for the first time in Guinea-Bissau in 2014.…”

Cashew as a High Agricultural Commodity in West Africa: Insights towards Sustainable Production in Guinea-Bissau

Abstract:In Sub-Saharan Africa, the West African region has highly diverse agro-climatic conditions, which grant the potential for a remarkable agricultural production of a great diversity of crops. Since the 1980s, the production volumes of most crops have grown vigorously for both domestic and export markets. Traditional food crops-such as rice, groundnuts and sorghum-have been replaced by cash crops, namely cashew. Among the main cashew production areas, West Africa is the most recent and dynamic in the world, accounting for 45% of the worldwide production of cashew nuts in 2015. In consequence, cashew cultivation has acquired an important position in West African smallholder farming, providing positive economic and social effects. In this paper, we provide an overview of the cashew production system in the West African region, using Guinea-Bissau as a case study. In particular, we present some viewpoints concerning the impact of cashew production and discuss how the strong dependence on a single cash crop can compromise the local livelihoods and food security. Finally, some insights are given towards the sustainable production of cashew in the face of the recent risks affecting the agricultural sector in West Africa.

“…In Guinea-Bissau, a study on new records of insect pest species associated with cashew, [61], reported Plocaederus ferrugineus, Apate terebrans and weaver ants as major pests of concern to cashew production. Their findings on the weaver ant as one of the major insect species affecting cashew production has been corroborated by this study.…”

Cashew (Anacardium occidentale L.), a recently recognized cash crop in Ghana, is an economically export oriented crop that plays a helping role in the Ghanaian economy in diverse ways. Owing to its importance, surveys were conducted in some major cashew producing communities in Dormaa and Berekum West District of the Bono region to assess the problems of insect pests and diseases associated with this economic tree across the study area. Diseased samples showing varying degrees of symptoms were taken for isolation and identification using morphological method. Insect pests were also assessed and identified. The results showed Colletotrichum gloeosporioides species complex to be associated with anthracnose, leaf lesions or spots, gummosis of twigs and stems and regressive die-back; Lasiodiplodia theobromae was found to cause stem and twig gummosis, blight, die-back of twigs and inflorescence; Pestalotia sp. was associated with Pestalotia leaf spot. Others, such as Penicillium sp., powdery mildew, Curvularia lunata, Cephaleuros sp. (red rust- algal leaf spot), mushroom and lichens were also found to be associated with the cashew orchards in the study area. Anthracnose, gummosis, algal leaf, and stem spots (red rust) and cashew kernel infection by Curvularia lunata constituted the major diseases of cashew in ascending order in the study area. The insect pests identified included Oecophylla smaragdina, Anoplocne miscurvipeson, Pseudotheraptus devastans, Pachnoda cordata, Pachnoda marginata, Helopeltis bug, Helopeltis schoutedeni, Planococcus sp., Lamida moncusalis, Odontotermes sp., Aphis sp., Analeptes trifasciata. Some unidentified pathogens, pests and other abnormalities were also observed.

“…This study would like to understand the relationship between cashew tree density and the damage caused by Apate terebrans (Coleoptera: Bostrichidae), one of the main insect pests of this crop in West Africa, particularly in Côte d'Ivoire (Aliko and Ouali N'Goran 2022;Topper et al 2001). The adult of this insect can cause the death of 30% of cashew trees, through the galleries it digs in the sapwood of the tree, in which it feeds and lives (Agboton et al 2017;Vasconcelos et al 2014). It is present in almost all cashew-producing regions in Côte d'Ivoire (Kouadio et al 2023), and control methods are mainly based on synthetic chemical products (Soro et al 2020b).…”

The stem borer Apate terebrans is a pest of tropical regions that considerably limits the production of cashew tree, an important crop for climate change adaptation. This study assessed the effects of cashew tree density on the damage of A. terebrans, for the effective and sustainable management of this insect pest. The density was characterised by the quadrat method in 10 orchards in the localities of Bondoukou and Bouna, in the north-east of Côte d'Ivoire. Based on systematic sampling, monthly counts of A. terebrans infestations were conducted on 1924 cashew trees from July 2018 to June 2020. Temperature and hygrometry were recorded over this period. In Bondoukou, an average density of 515 ± 235.5 cashew trees/ha was recorded, with a coefficient of variation (CV) of 58.64%. This density was significantly higher than that of Bouna (235 ± 39.6 cashew trees/ha), which showed low heterogeneity (CV = 29.44%). Temperature was higher in Bouna than in Bondoukou and vice versa for hygrometry. Linear regression showed a moderate and significant relationship between cashew tree density and damage, mainly in the locality with high spatial heterogeneity (i.e. Bondoukou). Thus, a high density reduces damage. The Morisita and Blackman indices indicated a distribution of damage that tended to be aggregated in Bondoukou and random in Bouna. By establishing the implication of cashew tree density in the control of A. terebrans damage, this work provides perspectives for the landscaping of cashew orchards, with a view to natural control of this pest.
