Morphological and behavioural evidence of relationships of the Cuckoo Finch Anomalospiza imberbis
Viduids are African finches that are obligate brood parasites, using other species to incubate their eggs and care for their young (Payne 1996, 1997a, b, 1998). Of 20 viduid species, 19 are indigobirds and whydahs in the genus Vidua, and one is the Cuckoo Finch Anomalospiza imberbis. Recent analysis of mtDNA sequence data supports the idea that Anomalospiza and Vidua are each others’ closest re...
متن کاملA cuckoo-like parasitic moth leads African weaver ant colonies to their ruin.
In myrmecophilous Lepidoptera, mostly lycaenids and riodinids, caterpillars trick ants into transporting them to the ant nest where they feed on the brood or, in the more derived "cuckoo strategy", trigger regurgitations (trophallaxis) from the ants and obtain trophic eggs. We show for the first time that the caterpillars of a moth (Eublemma albifascia; Noctuidae; Acontiinae) also use this stra...
متن کاملDoes coevolution with a shared parasite drive hosts to partition their defences among species?
When mimicry imposes costs on models, selection may drive the model's phenotype to evolve away from its mimic. For example, brood parasitism often drives hosts to diversify in egg appearance among females within a species, making mimetic parasitic eggs easier to detect. However, when a single parasite species exploits multiple host species, parasitism could also drive host egg evolution away fr...
متن کاملEffects of an African weaver ant, Oecophylla longinoda, in controlling mango fruit flies (Diptera: Tephritidae) in Benin.
Six mango, Mangifera indica L., plantations around Parakou, northern Benin, were sampled at 2-wk intervals for fruit fly damage from early April to late May in 2005. Mean damage ranged from 1 to 24% with a weaver ant, Oecophylla longinoda (Latreille), being either abundant or absent. The fruit fly complex is made up of Ceratitis spp. and Bactrocera invadens Drew et al., a new invasive species i...
متن کاملSeasonal Variation of Intestinal Parasitic Infections Among HIV-Positive Patients in Benin City, Nigeria
BACKGROUND There are a number of conflicting studies on the prevalence of intestinal parasitic infections in HIV infection with regards to different seasons. This study was conducted to determine seasonal influence on the prevalence of intestinal parasitic infections in HIV-positive persons in Benin City, Nigeria. METHODS Stool specimens from 2000 HIV-positive patients and 500 controls (HIV-n...
