Stems of trees, aged 3-4 years, were cut into 4 cm long pieces, dried naturally on the laboratory workbench, and placed in ventilated glass jars infested with 50 adult LGB which were 1-10 days old. Fifty grammes of maize (Zea mays L.) grains similarly infested with 50 adult LGB served as check. All the treatments were replicated four times and arranged in completely randomized design on the laboratory workbench. At 90 days postinfestation, the numbers of eggs, larvae, pupae, adult LGB (dead and living), holes on wood and maize grains; the weight of wood and maize dust; as well as % loss in weight of maize grains and wood were recorded. The highest mean numbers of eggs (91.0) and living LGB adults (152.0), and the highest % weight loss (79.6) were on maize and the values differed significantly (P<0.05) from those of the wood species. The stem cuttings of Macaranga barteri Muell. Arg. and Anogeisus leiocarpa Guill & Perrowere not damaged by the LGB but those of the remaining 13 species were damaged to varied extents.

Concerted efforts at controlling LGB should be evolved to prevent destruction of economic trees by the insect.","PeriodicalId":183712,"journal":{"name":"Nigerian Journal of Entomology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116989307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

F., by the pallid emperor moth, Cirinaforda Westwood, was studied from 2004-2006 in Aye Gber and Akaa Pila in Benue State, Nigeria. Observations were made on adult emergence from soil, copulation behaviour, oviposition, incubation period, larval density, feeding within tree canopy, damage, and natural enemies. Ten leaves were randomly selected from the lower, middle, and upper strata of the crown and the numbers of larvae on them were counted and transformed to (x + 0.5)1/2 for analysis. Defoliation was rated on a scale from 0-2 and transformed to Log 10 before analysis. Moths of C. forda emerged from the soil around the base of V. paradoxa from the last week of May in each year. Larval densities were high in the first two weeks of sampling, declining significantly thereafter. Larval density was significantly higher (P<0.05) in the lower stratum of the crown compared to the middle or upper stratum. Locational differences in larval density were not significant (tu>0.05) although numerically higher density was observed at Aye Gber than at Akaa Pila in 2004 -2006. The trees were partially defoliated in 2004 and 2005 but were completely defoliated in 2006 at both locations.

Two hundred and thirty four household heads comprising 128 (54.7%) males, 106 (45.3%) females, 80 (34.2%) civil servants, 67 (28.6%) business men and women, 57 (24.4%) farmers, and 30 (12.8%) students participated.

Eighty-two (35.0%) respondents considered cockroach infestation to be a potential health risk, 92 (39.3%) did not associate cockroach infestation with any health problem, and 60 (25.6%) were not sure that cockroaches transmit diseases.

While 75.2%) of the respondents reported that they felt embarrassed when visitors saw cockroaches in their homes, 58 (24.8%) said they were not embarrassed.
