Ceratitis Cosyra

The mango fruit fly (Ceratitis cosyra Walker) is the major pest of economic importance and which restricts mango exports from infested production areas in the SADC region. The effect of three pruning techniques, box/rectangle, spherical/round and the central leader, on assessing spatial distribution of fruit fly populations in high density mango production were investigated at Chiredzi Research station (21°01’S, 31°33’E) from 2010 to 2013. Results showed a significant rise in the number of adult fly catches among pruning techniques as from July to December (p< 0.05). Traps baited with Malathion 25% WP with molasses as an attractant were used to trap the flies. Results from all treatments indicated a significant rise in mean adult fruit fly catches from the months of July to December. It can be concluded that spatial distribution of the mango fruit fly is influenced by the fruiting and ripening patterns of mango.

Ceratitis Cosyra

Ceratitis cosyra is commonly known as the mango fruit fly or marula fruit fly based on its common occurrence in these host plants. Marula is a native African fruit related to mango and sometimes known locally as wild plum. The fly is a serious pest in smallholder and commercial mango across sub-Saharan Africa and has been recorded in Ivory Coast, Kenya, South Africa, Tanzania, Uganda, Zambia and Zimbabwe, where it is more destructive than either Mediterranean fruit fly (Medfly; Ceratitis capitata (Wiedemann)) or the Natal fruit fly (Ceratitis rosa Karsch) (Malio 1979; Labuschagne et al. 1996; Javaid 1979; De Lima 1979; Rendell et al. 1995; Lux et al. 1998). This document is EENY-286, originally published as DPI Entomology Circular 394, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

AbstractA fundamental question in medical genetics is how the genetic background modifies the phenotypic outcome of mutations. We address this question by focusing on the seam cells, which display stem cell properties in the epidermis of Caenorhabditis elegans. We demonstrate that a putative null mutation in the GATA transcription factor egl-18, which is involved in seam cell fate maintenance, is more tolerated in the CB4856 isolate from Hawaii than the lab reference strain N2 from Bristol. We identify multiple quantitative trait loci (QTLs) underlying the difference in phenotype expressivity between the two isolates. These QTLs reveal cryptic genetic variation that reinforces seam cell fate through potentiating Wnt signalling. Within one QTL region, a single amino acid deletion in the heat shock protein HSP-110 in CB4856 is sufficient to modify Wnt signalling and seam cell development, highlighting that natural variation in conserved heat shock proteins can shape phenotype expressivity.

Abstract The Mediterranean fruit fly, Ceratitis capitata, is a devastating agricultural pest that threatens to become established in vulnerable areas such as California and Florida. Considerable controversy surrounds the status of Californian medfly infestations: Do they represent repeated introductions or the persistence of a resident population? Attempts to resolve this question using traditional population genetic markers and statistical methods are problematic because the most likely source populations in Latin America were themselves only recently colonized and are genetically very similar. Here, significant population structure among several New World medfly populations is demonstrated through the analysis of DNA sequence variation at four intron loci. Surprisingly, in these newly founded populations, estimates of population structure increase when measures of subdivision take into account the relatedness of alleles as well as their frequency. A nonequilibrium, likelihood-based statistical test that utilizes multilocus genotypes suggests that the sole medfly captured in California during 1996 was introduced from Latin America and was less likely to be a remnant of an ancestral Californian population. Many bioinvasions are hierarchical in nature, consisting of several sequential or overlapping invasion events, the totality of which can be termed a metainvasion. Phylogenetic data from multilocus DNA sequences will be vital to understanding the evolutionary and ecological processes that underlie metainvasions and to resolving their constituent levels.
