Corals perform simultaneous mass spawning around the full moon. Most Acropora species release gamete bundles, which are a complex of eggs and sperm, into the seawater. Then, gamete bundles are separated into eggs and sperm. Eggs are fertilized when sperm and eggs come in contact with each other. However, it is still unclear how sperm meet the eggs of the same species in the presence of many egg...

INTRODUCTION Aedes aegypti eggs can be collected from the water surface. METHODS Aedes aegypti oviposition from 97 field ovitraps was studied. RESULTS Of the 16,016 eggs collected, 11,439 were obtained from paddles in ovitraps and 4,577 from water. Further, 89 (91.8%) traps contained eggs on water and 22 (22.7%) traps contained eggs only on water. CONCLUSIONS In field traps, Aedes aegypti...

The precise occurrence of Opisthochis viverrini infection in humans, who were positive for Opisthorchis-like eggs in a stool examination, was determined using the potassium permanganate staining method. In the 68 specimens examined, there were more individual O. viverrini eggs (38.24%) than singular Haplorchis taichui eggs (29.41%). One-fourth of the total specimens contained a mixed infection ...

Egg-laying behavior of free-living Willow Ptarmigan (Lagopus lagopus) was studied at Chilkat Pass, B.C. to learn if females were indeterminate egg-layers in natural conditions. Eggs were removed from clutches of experimental birds during laying, usually beginning with the third egg. All birds were determinate egg-layers and there was no difference in the number of eggs laid by control (K = 8.11...

The effect of multiple immersions on Haemagogus janthinomys , Haemagogus leucocelaenus , Aedes albopictus and Ochlerotatus terrens eggs was studied. Eggs were collected in April, June, October and December of 2011 in Minas Gerais, Brazil. Most of the Aedes and Ochlerotatus eggs hatched upon the first immersion, while Haemagogus eggs showed a varied instalment hatching response. The number of im...

The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...

I love eggs. Always have, and I expect I always will. Eggs are an easy, quick and inexpensive source of protein, and with my busy professional and personal life, I need protein to stay grounded. I remember when there was hype about eggs having too much cholesterol. People were cutting out eggs and resorting to some form of liquid egg in a carton. I didn’t buy into it, and continued eating my da...

Tires that were either crudely chopped or more finely processed into shreds contained viable eggs. Field-collected remnants of 2-3 chopped tires contained viable Aedes albopictus eggs. After shredding tires seeded with mosquito eggs, 34 (4.6%) of an estimated 746 Ae. albopictus eggs and 21 (2.7%) of an estimated 774 Aedes triseriatus eggs survived. Chopped and shredded tire remnants may serve a...

Shiny cowbirds, Molothrus bonariensisparasitized a high frequency (average 48%) of nests in five colonies of chestnut-capped blackbirds, Agelaius ruficapillusin Argentina. Two distinct egg morphs occurred, spotted and immaculate white eggs, as well as a few very lightly spotted intermediate eggs. The clear differences between morphs, combined with considerable variation in spotting pattern betw...

We have obtained gram quantities of clean, viable eggs of Meloidogyne incognita by a method which combined treatment with hypochlorite and differential centrifugation. Chili pepper plants (Capsicum frutescens L.) infected with M. incognita were dug at harvest from a naturally infested field. Egg sacs from roots of 50 plants were obtained by kneading the washed roots in water and recovering the ...
