New Host Plant Records for Species Of
Life: The Excitement of Biology 4(4) 272 Geometric Morphometrics Sexual Dimorphism in Three Forensically- Important Species of Blow Fly (Diptera: Calliphoridae)1 José Antonio Nuñez-Rodríguez2 and Jonathan Liria3 Abstract: Forensic entomologists use adult and immature (larvae) insect specimens for estimating the minimum postmortem interval. Traditionally, this insect identification uses external morphology and/or molecular techniques. Additional tools like Geometric Morphometrics (GM) based on wing shape, could be used as a complement for traditional taxonomic species recognition. Recently, evolutionary studies have been focused on the phenotypic quantification for Sexual Shape Dimorphism (SShD). However, in forensically important species of blow flies, sexual variation studies are scarce. For this reason, GM was used to describe wing sexual dimorphism (size and shape) in three Calliphoridae species. Significant differences in wing size between females and males were found; the wing females were larger than those of males. The SShD variation occurs at the intersection between the radius R1 and wing margin, the intersection between the radius R2+3 and wing margin, the intersection between anal vein and CuA1, the intersection between media and radial-medial, and the intersection between the radius R4+5 and transversal radio-medial. Our study represents a contribution for SShD description in three blowfly species of forensic importance, and the morphometrics results corroborate the relevance for taxonomic purposes. We also suggest future investigations that correlated shape and size in sexual dimorphism with environmental factors such as substrate type, and laboratory/sylvatic populations, among others. Key Words: Geometric morphometric sexual dimorphism, wing, shape, size, Diptera, Calliphoridae, Chrysomyinae, Lucilinae Introduction In determinig the minimum postmortem interval (PMI), forensic entomologists use blowflies (Diptera: Calliphoridae) and other insects associated with body corposes (Bonacci et al.

Abstract Lucilia cuprina is one of the forensically important Calliphoridae fly. L. cuprina is a helpful resource at the crime scenes as well as a nuisance to sheep. It is known to be one of the first flies to occupy a corpse upon its death. Due to this, it has great importance in forensic field to find out post-mortem interval. In this study, the development of L. cuprina is studied in an incubator at different constant temperatures.

Toleration of Lucilia Cuprina (Diptera: Calliphoridae) Eggs to Agitation Within Insect Saline
Toleration of Lucilia cuprina (Diptera: Calliphoridae) Eggs to Agitation Within Insect Saline Christina Kaye Alvarez and Dr. Adrienne Brundage Editor: Colton Cooper Abstract: Microorganisms have an ability to attach themselves to surfaces, where they then multiply and form a protective biofilm, which protects the microorganisms from outside influences, including chemicals for sanitation. This makes the cleaning of fly eggs for maggot therapy difficult. The purpose of this study was to test the toleration of Lucilia cuprina (Wiedemann) (Diptera: Calliphoridae) eggs for agitation, which is used to degrade biofilms. Lucilia cuprina eggs were washed with insect saline and treated by undergoing five minutes of agitation. It was found that there was a significant difference between the control group, which did not undergo any agitation, and the treatment group, which did. This knowledge is useful for further testing of the extent to which agitation impacts survivability of the eggs and the debridement of the biofilm.

ZooKeys 420: 69–85. doi: 10.3897/zookeys.420.7645 Abstract Hybrids of Lucilia sericata and Lucilia cuprina have been shown to exist in previous studies using molecu- lar methods, but no study has shown explicitly that these hybrids can be identified morphologically. Pub- lished morphological characters used to identify L. sericata and L. cuprina were reviewed, and then scored and tested using specimens of both species and known hybrids. Ordination by multi-dimensional scaling indicated that the species were separable, and that hybrids resembled L. cuprina, whatever their origin. Discriminant function analysis of the characters successfully separated the specimens into three unam- biguous groups – L. sericata, L. cuprina and hybrids. The hybrids were morphologically similar irrespective of whether they were from an ancient introgressed lineage or more modern.

Email: *[email protected] Received February 8th, 2012; revised March 17th, 2012; accepted April 2nd, 2012 ABSTRACT Preservation of viable tissue is important in wound management. It is achieved by small, incremental removal of de- vitalised, necrotic and infected tissues. Maggot debridement therapy (MDT) is used in septic necrotic wounds that fail to respond to conventional modalities. MDT has relied on Lucilia sericata, which consumes only necrotic tissues, as opposed to Lucilia cuprina, which devours both flesh and necrotic tissues. Recent findings have shown that L. cuprina consumes mainly necrotic and very small amounts of viable tissues and may be used in MDT where L. sericata is very rare or absent. Here we describe wound healing in a patient from rural South Africa with cutaneous myiasis. Our find- ings agree with workers who indicated that L. cuprina could be used in MDT.

Sheep Blowfly Biology
Sheep blowfly biology The Australian sheep blowfly, Lucilia cuprina, is responsible for initiating over 90% of sheep flystrikes in Australia. It preferentially, but not exclusively, breeds on sheep. Several other blowfly species are sometimes involved in flystrike but each of these breeds mainly in carrion. The L. cuprina life-cycle (figure 1) is intimately linked with sheep. Variation in strike incidence relates mainly to the occurrence of susceptible sheep, not the density of sheep blowflies in the area. Trap catches of as few as 1-2 flies / hour, or estimated densities of 7-10 blowflies / hectare are enough to cause extensive strike if susceptible sheep are present. Sheep blowflies cannot lay eggs until they have consumed a protein meal. They then mate and the female flies develop eggs. Depending on the size of the female, batches of up to 200 eggs can be laid per ovarian cycle. Sheep blowflies can live for over a month in the field. During this time three batches of eggs may be laid. L. cuprina eggs are not laid indiscriminately. Female flies seek out susceptible sheep. Putrefactive odours and odours associated with fleece rot bacteria or dermatophilosis are particularly attractive. Initially females are attracted by smell. Later visual cues are used. When a susceptible sheep is found, the preferred oviposition site is located using taste receptors on the tarses (feet), mouthparts and finally the ovipositor (genitalia). The eggs are susceptible to desiccation, but there is safety in numbers. Ovipositing females produce a contact pheromone to entice other females to lay at the same site. Susceptible sheep may have very large egg masses laid on them by dozens of flies.

GPO Box 1700, Canberra ACT 2601, Australia Field-femalekilling (FK) systems based on deleterious mutations arid Y-autosome translocations are being evaluated for genetic control of the Australian sheep blowfly, Lad/ia cuprina. Experience during field trials has shown that mass-reared colonies of FK strains are subject to genetic deterioration, caused mainly by genetic recombination in males. A previous study found higher male recombination frequencies in two Y-linked translocation strains than in chromosomally normal males. However, the results of the present study indicate that breakage of the Y chromosome is neither sufficient nor necessary for increased levels of male recombination. The fre- quency of male recombination appears to be unrelated to the presence of specific chromosome rearrangements. Keywords:genetic control,genetic sexing, Lad/ia cuprina, male recombination.
