“…In the Free-choice test, the low preference of Anti-Ota was traced to its high cyanide content as reported by Dufour (1987). Similarly, Daramola (1981) reported that the least preferred oviposition medium by the kola nut weevil, Balangastris kolae contained high caffeine content. Therefore, the low egg output on Anti-Ota is indicative of the presence of some oviposition deterrents in this cassava cultivar.…”

Effect of cassava varieties on oviposition and development of larger grain borer-Prostephanus truncatus horn (Coleoptera: Bostrichidae)

The influence of cassava varieties on the developmental biology of Prostephanus truncatus (Horn) was investigated. This beetle was reared on flour varieties of cassava, namely: Danwari, Nwugo, Aburu-Asua and Ant-Ota. More eggs were la d in Danwari (132.0 i i + 6.1 egg) than in other cassava variety. The least number of eggs laid was in Nwugo (118.3 +-4.5) in No-choice experiment. In Freechoice test, the highest number of eggs was recorded in Aburu-Asua (64.0 + 1 7 eggs) and the lowest (41.6. + 3 1 eggs) on Anti-Ota. The average total developmental period in, Aburu-Asua, Nwugo, Danwari and Ant-Ota were 32.5. i + 0.4, 30.6 + 0.2, 28.5 + 0.1 and 34.7 + 0.1 days respectively. The low oviposition preference for Nwugo was attributed to the presence of oviposition deterrents in this variety, which might have protected it against the beetle attack.

“…The major pest of kolanuts informed by farmers was kolanut weevil. Kolanut weevils are major pest of kolanuts both prior to the harvest and during storage [3,4,13,[19][20][21]. Kolanut weevil was also discovered by Asogwa et al [22] as the most destructive insect pest of kolanut in kolanut growing belt of Nigeria.…”

“…About 40 Cola species have been described in West Africa; however, the Cola species of economic importance in Nigeria are C. acuminata and C. nitida [1][2][3][4]. Both species are important economic crops in the forest areas of West and Central Africa, Carribean Islands, Mauritius, Sri Lanka, and Malaysia [5].…”

Potentials and Challenges of Kolanut Production in Niger State, Nigeria

et al. 2012

View full text Add to dashboard Cite

Niger State has unique history of kolanut production in northern part of Nigeria. Unfortunately, the potentials of kolanut production in the state are not duly recognized. Lavun and Mokwa Local Government Areas, where kolanut is widely produced were selected for the study. Kolanut farmers were randomly selected for administration of structured questionnaire. Cola nitida was the dominant species planted by the farmers. More than two third of the kolanut plantations were 60 years and above. Kolanut farms were mainly owned through inheritance. Farmers at Lavun adopted more cultural practices than the farmers at Mokwa; such practices included application of organic manure and mulching to the kolanut trees, felling of unproductive kolanut trees to coppice, and adoption of multiple land practice. Due to this, the farmers at Lavun got more harvest from their kolanut plantations than those at Mokwa. Stored nuts were mainly attacked by weevils and rot disease. Challenges of kolanut production are low yield, lack of information on improved technology, pest and disease infestation, lack of intervention from the government, and transportation. Farmers in the study areas still hold kolanut production in high esteem, and there is vast area of land which could be used for kolanut production.

“…are important economic crops in West and Central Africa, Carribean Islands, Mauritus, Sri Lanka and Malaysia Oladokun [1]. Though Cola verticillata is less important due to the nuts' foamy nature when chewed Daramola [2]. However, Cola acuminata and Cola nitida (Schott and Endl) are the only edible species of kola nuts grown in commercial scale in Nigeria Jacob [3].…”

Checklists of Field and Storage Insect Pests of Kola Nuts, (Cola Nitida; Cola Acuminata)i - A Review

Several insect pests attack kola nuts (Cola nitida; Cola acuminata) both in the field and storage but only twenty common species of economic importance are discussed within the purview of this work. The fecundity, developmental (i.e. Biology/life cycle) stages and damage characteristics including control measures (i.e. chemical, mechanical/physical, and cultural methods, use of natural enemies and botanicals etc) were examined. Insect pests were classified as either minor or major based on the degree of damage caused to kola nuts. Kola nuts do not require further processing before consumption thus any minute chemical residue is deemed unacceptable. Chemical for storage pests are used sparingly hence uses of bio-rational or botanical insecticide are also explored. Moreover, the studies of population dynamics in Kola producing farms have enhanced proper taxonomy and enable formulation of standard integrated packages for insect pest management.
