Global attractivity in Nicholson’s blowflies
Applied Mathematics, 1996The author studies the delay differential equation \[ N'(t)=-\delta N(t)+pN(t-\tau)\exp(-aN(t-\tau)),\quad t\geq0, \] used in describing the dynamics of Nicholson's blowflies. When \(p>\delta\), he establishes sufficient conditions for the global attractivity of the nontrivial equilibrium.

The Climatology of Blowfly Myiasis
Bulletin of Entomological Research, 1947The relationship of oviposition to weather, with a standard stimulus (4 per cent. ammonium carbonate), has been tested by a series of 134 exposures of a group of three sheep for one hour. 190 egg clusters were obtained, of which 169 were identified. With the exception of one cluster of L. caesar all were L. sericata.There was a fairly close correlation

Engagement of the phallosome in blowflies
Journal of Entomology Series A, General Entomology, 1975SYNOPSIS The engagement of male and female parts during copulation is described in detail for Lucilia sericata Meigen. The occurrence on the phallosome of lateral ducts and apertures for accessory gland secretion is reported for a number of species of Calliphorinae.

The evolution of myiasis in blowflies (Calliphoridae)
International Journal for Parasitology, 2003Blowflies (Calliphoridae) are characterised by the ability of their larvae to develop in animal flesh. Where the host is a living vertebrate, such parasitism by dipterous larvae is known as myiasis. However, the evolutionary origins of the myiasis habit in the Calliphoridae, a family which includes the blowflies and screwworm flies, remain unclear ...

The halteres of the blowfly Calliphora
Journal of Comparative Physiology A, 1993We quantitatively analysed compensatory head reactions of flies to imposed body rotations in yaw, pitch and roll and characterized the haltere as a sense organ for maintaining equilibrium. During constant velocity rotation, the head first moves to compensate retinal slip and then attains a plateau excursion (Fig. 3). Below 500°/s, initial head velocity

The American Journal of Surgery, 1934
Abstract The separation and sterilization of blowfly eggs are significant factors in the culture of sterile maggots for use in the treatment of suppurative infections. Experiments were conducted on the separation of eggs and a method was devised by which they can be separated rapidly and without loss or injury.
