Homozygous-viable pericentric inversions for genetic control of Lucilia Cuprina

Theoretical and Applied Genetics, 1991
The isolation of homozygous-viable pericentric inversions for inclusion in field-female killing (FK) systems in Lucilia cuprina is described. From 7,236 irradiated chromosomes screened, 16 pericentric inversions were isolated. Four of these were viable as homozygotes.

Meiotic Drive in Lucilia cuprina and Chromosomal Evolution

The American Naturalist, 1991
In females heterozygous for pericentric inversions that alter the relative lengths of the long and short arms of a chromosome, crossing-over within the inversion can lead to unequal segregation at anaphase II, favoring the homologue with the more centrally located centromere.

Selection for insecticide resistance in the Australian sheep blowfly,Lucilia cuprina

Experientia, 1982
Egg implant studies on sheep demonstrate that the relative fitness of resistance genotypes of the sheep blowfly, Lucilia cuprina, changes over time for the 2 insecticides dieldrin and diazinon. The results suggest that selection may occur following exposure of larvae to sub-lethal concentrations and help to explain the relative rates of the development

Melanin in an Insect, Lucilia cuprina (Wied.)

Nature, 1967
MELANINS, although somewhat ill defined, are dark pigments which occur in animals and plants and they are usually bound to protein. Thomson1 in a review has pointed out that there are no satisfactory histochemical tests for the identification of melanin.

Hypersensitivity responses and repeated infections with Lucilia cuprina, the sheep blowfly

International Journal for Parasitology, 1992
Sheep repeatedly infected with L. cuprina at 2- but not 4-week intervals developed partial resistance to infection after five infections, as measured by larval recovery. However, resistance did not persist for more than three infections. Skin weal responses were measured after injection of larval products simultaneously with each infection.

Insecticide resistance and malathion carboxylesterase in the sheep blowfly,Lucilia cuprina

Biochemical Genetics, 1994
Resistance to the organophosphorus insecticide malathion in genetically related strains of the Australian sheep blowfly Lucilia cuprina was examined. Separate lines of blowflies were established by homozygosis of the fourth chromosome of the parental RM strain.

Prothoracic gland hormone in the sheep blowfly, Lucilia cuprina

Journal of Insect Physiology, 1970
Abstract Variations in the amount of prothoracic gland hormone during the development of Lucilia cuprina from the third larval instar to adult ecdysis have been investigated. The level falls from moderately high values in the late third instar larva to a minimum 6 hr after the larval-pupal apolysis, before rising very sharply to a peak at 12 hr.

Germ‐line transformation of the Australian sheep blowfly Lucilia cuprina

Insect Molecular Biology, 2002
Abstract The Australian sheep blowfly, Lucilia cuprina , is the most important economic insect pest for the sheep industries in Australia and New Zealand. piggyBac ‐mediated germ‐line transformation of L. cuprina

Vaccination of sheep against larvae of the sheep blowfly (Lucilia cuprina)

Vaccine, 1996
Four first stage larval antigens from the sheep blowfly were identified using supernatants from cultures of antibody secreting cells. These partially purified larval antigens, when added to Montanide ISA-25 containing recombinant ovine IL-1 beta (rovIL-1 beta) were used to successfully vaccinate sheep against larvae of the sheep blowfly.

Antibody responses to Lucilia cuprina in sheep selected for resistance or susceptibility to L. cuprina

Parasite Immunology, 1997
Sheep bred for resistance (R) or susceptibility (S) to fleece rot and myiasis (blowfly strike) have been shown to differ in inflammatory response to intradermal administration of blowfly (Lucilia cuprina) antigens and artificial challenge. The current paper describes analysis of antibody responses to L. cuprina antigens in the R and S animals.
