Susceptibility of Nezara Viridula (L.) (Hemiptera: Pentatomidae) egg masses of different sizes to parasitism by Trissolcus Basalis (Woll.) (Hymenoptera: Platygastridae) in the field
(Sociedade Entomológica Do Brasil, 2013-11)
Egg masses of Nezara viridula (L.) are commonly parasitized by Trissolcus basalis (Woll.), and we investigated the role of size of egg masses on parasitization by T. basalis. Sentinel egg masses were exposed to parasitism ...
Variation in the size of eggs of Kelp Gulls (Larus dominicanus) at two colonies in Patagonia, Argentina
(Waterbird Soc, 2015)
Although several studies have reported basic information about the size of Kelp Gull (Larus dominicarius) eggs, no attention has been paid to the comparison of patterns of intra-clutch variation at different breeding sites. ...
Yolk mass variation in White-rumped Swallows (Tachycineta leucorrhoa)
(Wilson Ornithological Society, 2014-03)
Egg mass production is costly, but hatching from heavier eggs could be beneficial for the nestling's phenotype and fitness. Egg mass could be influenced by proximate causes, like food abundance, female condition, environmental ...
Effects of Ascorbic Acid Injection in Incubated Eggs Submitted to Heat Stress on Incubation Parameters and Chick Quality
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2015-04-01)
Dose-dependent positive effects on hatchability and hatchling weight have been attributed to ascorbic acid (AA) when eggs were submitted or not to intermittent heat stress during incubation. Fertile breeder (Cobb (R)) eggs ...
On the egg masses, eggs and embryos of Notocochlis isabelleana (D'orbigny, 1840) (Gastropoda: Naticidae) from Northern Patagonia
(Institute of Malacology, 2009-08)
Naticids are common predators in sandy bottoms of shallow waters around the world. Probably due to their infaunal habitat, they are hard to find alive, particularly in the Patagonian waters of Argentina. Nevertheless, their ...
Effect of organic selenium and zinc on the performance and egg quality of Japanese quails
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-06-01)
The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. ...
Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) Oviposition Behavior in Previous Oviposition Situation
(2016-10-01)
Blowflies use their sense of smell to locate oviposition substrates and their vision to direct and assist in landing decision. Blowflies’ ovipositions are usually aggregated. Chrysomya megacephala (Fabricius) females, for ...
Digestible threonine-to-lysine ratio in diets for brown egg-laying hens
(Oxford Univ Press, 2019-03-01)
The objective of this study was to evaluate the levels of digestible threonine to determine the ideal digestible threonine-to-lysine ratio in the diet of brown egg-laying hens aged 42-54 wk. A total of 270 Dekalb Brown ...
THERMAL REQUIREMENTS OF Ceraeochrysa cubana (Neuroptera: Chrysopidae) EMBRYONIC PERIOD SUBMITTED TO ARTIFICIAL DIETS AT ADULT STAGE
(Univ Federal Uberlandia, 2018-11-01)
Green lacewings can be mass reared to market their eggs. The ideal temperature is a main factor for egg storage or scheduling of insect production. This study aimed to evaluate the influence of Ceraeochrysa cubana adult ...
