“…As a result, an increase in the production of these crops in the global traditional agricultural system has been recorded (Ogazi, 1996 andNwosu andLawal, 2010) and therefore any short fall in their availability will adversely affect the health of man and impinge on his economy. PANS (1977), Kerrmarrec et al, (1993) and Mclntye et al, (2001) recorded that numerous insect pests attack banana and plantain crops while Gowen (1995) and Gold and Messiaen (2000) stressed that among the concerned insect pests, Cosmopolites sordidus (the banana weevil) is the principal pest of banana and plantain crops, affecting seriously the pseudo stem and rhizome.…”

“…Therefore, this study sought to document the prevalence of C. sordidus (an important pest of banana and plantain) in a banana and plantain doing -well environment with a view to projecting their actual level of economic importance in the area and providing new insight on the biology of this species. In addition, the relationship between site of crop plot and banana/plantain pests with regards to either receiving or not receiving treatment from living homes (Nwosu and Lawal, 2010) deserves further investigation.…”

“…Banana and plantain (Musa spp) are important food and cash crops (FAO, 1995;Nkendah and Akyeampong, 2003;Nwosu and Lawal, 2010) with outstanding and proven medical and industrial relevance (Rahman, 1964;Paul and Southgate, 1978;Ogazi, 1996;Faturobi et al, 2007). As a result, an increase in the production of these crops in the global traditional agricultural system has been recorded (Ogazi, 1996 andNwosu andLawal, 2010) and therefore any short fall in their availability will adversely affect the health of man and impinge on his economy.…”

In a study of the assessment of the banana weevil, Cosmopolites sordidus in an environment that sustains high production of banana and plantain in Ondo State, Nigeria, low levels of C. sordidus population and infestation were discovered. Population surveys of the weevil were conducted in randomly selected crop plots near living homes (< 500m) and far from living homes (> 500m). Investigation was done by the use of trapping systems, dissections of cut decaying pseudo stems and culturing of immature stages of insects to adulthood. A total number of 23 C. sordidus (Coleoptera: Curculionidae) were collected from 50 sampled plots that showed 10% infestation. Number of nearliving home infested plots 2 (4%) did not significantly differ (P>0.05) from number of far-from living home 3 (6%) infested plots. The result of this study also showed that the number of the pest found in banana and plantain crops in plots near living homes 11 (47.83%) did not significantly differ (P> 0.05) from those in plots far from living homes 12 (52.17%). This suggests that site of crop plot has no obvious impact on the prevalence of C. sordidus in banana and plantain communities. In this study, the relationship between backyard / kitchen waste and the population of C. sordidus needs further investigation while the low population and infestation levels recorded strongly indicate cultural practice effect.

This study investigated the influence of type of electric bright light (produced by fluorescent light tube and incandescent light bulb) on the attraction of the African giant water bug, Lethocerus indicus (Hemiptera: Belostomatidae). Four fluorescent light tubes of 15 watts each, producing white-coloured light and four incandescent light bulbs of 60 watts each, producing yellow-coloured light, but both producing the same amount of light, were varied and used for the experiments. Collections of bugs at experimental house were done at night between the hours of 8.30 pm and 12 mid-night on daily basis for a period of four months per experiment in the years 2008 and 2009. Lethocerus indicus whose presence in any environment has certain implications was the predominant belostomatid bug in the area. Use of incandescent light bulbs in 2009 significantly attracted more Lethocerus indicus 103 (74.6%) than use of fluorescent light tubes 35 (25.41%) in 2008 [P < 0.05; P (Z > 4.92) = 0.0001]. However, bug's attraction to light source was not found sex dependent [P > 0.05; P (Z > 0.18) = 0.4286 and Z > 0.28 = 0.3897]. Therefore, this study recommends the use of fluorescent light by households, campgrounds, and other recreational centres that are potentially exposed to the nuisance of the giant water bugs. Otherwise, incandescent light bulbs should be used when it is desired to attract the presence of these aquatic bugs either for food or scientific studies.

Ants are one of the most ubiquitous, widespread and abundant groups of animals on Earth. They are eusocial and are well noted for their important ecosystem services such as nutrient recycling, seed dispersal, engaging in mutualistic associations with other organisms, as well as serving as predators and scavengers. Although Africa has been recognised as a global hotspot for ant diversity, African ant genera are not as well-known when compared with other regions. The last checklist of Nigerian ants was compiled and published in the 1970s. To contribute to new knowledge on West African ant genera and Nigeria in particular, we conducted a review of the ant species of Nigeria using 132 scientific publications mostly compiled in the database www.antmaps.org, along with a survey of ant species of Lagos and Oyo States in Nigeria which was conducted between 2018 and 2020. The study aimed to ascertain the diversity of Nigerian ant genera, as well as to confirm the presence of previously recorded species and add new species to the current checklist of Nigerian ants, based on the 1970 survey. As many as 106 species were recorded from the survey in the current study, of which 28 are new to Nigeria and additional 28 are identified to the morphospecies level. In total, 317 species from 10 subfamilies and 64 genera are now recorded from Nigeria, including 11 invasive ants, of which six are new to Nigeria. The following eleven species that were included in the 1970 checklist were excluded from the current list, mostly due to previous misidentifications: Aenictus rotundatus Mayr, 1901; Anochetus jonesi Arnold, 1926; Camponotus barbarossa micipsa Wheeler, 1992; Camponotus foraminosus dorsalis Santschi, 1926; Camponotus rufoglaucus (Jerdon, 1851); Cardiocondyla zoserka Bolton, 1982; Messor barbarus (Linnaeus, 1767); Odontomachus haematodus (Linnaeus, 1758); Technomyrmex albipes (Smith, 1861); Tetramorium decem Forel, 1913 and Tetraponera penzigi (Mayr, 1907).
