Swarming behaviour of the mammalophilic simuliids Wilhelmia equina, W. salopiensis and Boophthora erythrocephala is closely related to sex-finding. Long-range orientation occurs by optically directed swarming of the ♂♂ towards a dark marker above them contrasting with the bright sky. ♀♀ flying directly to the same marker or the bigger object carrying it, e.g. a tree, are visually recognized by the ♂♂ at a short distance (short-range orientation). 
ON THE SWARMING OF AUSTROSIMULIUM PESTILENS MACKERRAS AND MACKERRAS (DIPTERA:SIMULIIDAE)
TLDR
Austrosimulium pestilens was found to exhibit two distinct types of aggregation, one concerned with mating, the other with oviposition, both of which were observed throughout the daylight hours. Expand
Quantitative aspects of sperm transfer in Simulium decorum (Diptera: Simuliidae)
TLDR
The mean number of sperm ejaculated into the spermatophore by the male black fly, Simulium decorum Walker, was 4048, as determined from 43 counts, and transfer rate was interpreted as constant at about 73 sperm/min and was usually completed by about 55 min after copulation. Expand
Koevolution von Überträger und Parasit bei Simuliiden und Nematoden1
TLDR
A similar but local coincidence apparently exists in the skin of the body regions which are attacked by the vectors and entered by the microfilariae of the appropriate Onchocerca filariae. Expand

Oocyte maturation in the black fly, Simulium underhilli Stone and Snoddy, resulting from blood enemas.
TLDR
There was a direct relationship between the volume of blood administered and the number of oocytes matured in laboratory-reared females of Simulium underhilli Stone and Snoddy and the implications for rearing, infection, and age determinations. Expand
Mating Activity of the Mammalophilic Blacklies Simulium (Wilhelmia) Lineatum (Meigen, 1804) (Diptera: Simuliidae) Under Laboratory Conditions
The diurnal rhythm of mating activity of the blackflies Simulium (W.) lineatum was established: 88–94% of insects were ready to mate during the daytime (6:00 a.m. – 7:00 p.m.), and 29–53% atExpand
Tagesrhythmen lappländischer Simuliiden (Diptera)
TLDR
The larvae feed during all hours of the day and the number of moults and pupations reaches its maximum in the afternoon, and under artificial LL and DD the Simuliidae emerge two hours after a rise in temperature. Expand
SWARMING OF LONCHAEID FLIES AND OTHER INSECTS, WITH DESCRIPTIONS OF FOUR NEW SPECIES OF LONCHAEIDAE (DIPTERA)
TLDR
Evidence is presented to show that various swarming habits and associated morphological adaptations are primitive features of not only the Lonchaeidae, but of all Diptera. Expand
Behavioural analysis of feeding and reproduction in haematophagous insects
TLDR
Feeding and reproductive behaviours of haematophagous insects are analysed on certain hierarchy of events like: motivation; search and consummation. Expand
Über die Spermatophore von Boreus westwoodi Hagen (insecta, mecoptera)
  • G. Mickoleit

  • Zeitschrift für Morphologie der Tiere
  • 2004
TLDR
The author presumes that the redevelopment of a spermatophore in Boreus westwoodi is connected with the formation of a secondary ovipositor and the correlated caudal shift of the opening of the genital chamber in the female. Expand

A Study of Flight Range and Longevity of Blackflies (Diptera, Simuliidae) Infected with Onchocerca Volvulus
TLDR
This study aims to explain the restricted distribution of the disease in Guatemala by showing the effect of infection on the flight range and longevity of the flies, and to formulating effective anti- Similium measures for the control of human onchocerciasis. Expand
Use of P32 in the study of a population of Simulium rugglesi (Diptera: Simuliidae) in Algonquin Park, Ontario.

Longevity and further Flight Range Studies on the Blackflies (Díptera, Simuliidae), with the Use of Dye Markers.
TLDR
It must be determined whether or not infection with the immature stages of Onchocerca adversely affects the flight range and longevity of blackflies, and to what extent infiltration by the flies from non-treated to treated areas might be expected. Expand

A new character for the recognition of nulliparous females of Anopheles gambiae
TLDR
It is shown that the proportion of plug-positive and of unfertilized females in outside resting populations of A. gambiae was approximately doubled following the application of a residual insecticide to houses. Expand
The Reproductive System of Some Florida Mosquitoes. II. The Male Accessory Glands and Their Role
TLDR
The quantity of fluid in the male glands diminishes with successive matings, as does the number of spermatozoa in the seminal vesicles, and changes in the shape and appearance of the glands follow multiple matings. Expand
Observations on Mating, Feeding, and Oviposition of Some Utah Species of Black Flies (Diptera: Simuliidae)
TLDR
During recent studies on the blackfly fauna of Utah, observations were made on mating, feeding, and oviposition of several species of black flies for which such data are fragmentary or completely lacking. Expand

TLDR
Nineteen Ontario species were studied and five from outside Ontario examined, finding that male mating flights occurred in species of Prosimulium and Simulium but S. decorum and S. mutata fed infrequently on deer. Expand
