With the exception of December-burrowing crawfish in season 1, in which oviposition
occurred during mid February, there is a low probability that a high percentage of juveniles from spawns occurring after about mid March (i.
Inter species interference of oviposition
behaviour in the cowpea weevils Callosobruchus rhodesianus (Pic) and Callosobruchus maculatus (F.
White (1981) found that the number of eggs that die in flagged branches depended on how long the branch remained alive after oviposition
guianense were observed in oviposition
activity in the morning (8:00 am), using as substrate submerged and/or partially submerged vegetation (Figs.
Specifically, the link between known endocrine disruptors, such as plastics pollutants, and oviposition
behavior of B.
process, the adult female remained stationary for some time and then lowered the posterior region of the hystorosoma for laying eggs.
Prior to statistical analysis, sampling dates were converted to "egg-age" in days by subtracting the date of oviposition
from the date of sampling.
This study (1) describes sequence and duration of events before and after oviposition
, (2) characterizes a previously undescribed vocalization in gulls associated with oviposition
, (3) reports when, and the conditions under which, eggs are laid and lost to predation and/or cannibalism, and (4) makes predictions about underestimations in daily egg censuses.
Evaluating Deterrent Effects of ESAM on Oviposition
substrate was a 12 x 2 cm strip of a 9 mm plywood wooden paddle covered by 9 x 2 cm strip of Whatman 42 filter paper fixed by a rubber band at one end and then placed vertically inside the container.
We did not collect egg sacs for the first seven days of any month in order to more accurately assign sacs with eggs to the correct month of oviposition
The defensive postures in these Myrmicine ants reportedly either impeded oviposition
by the flies, or more rarely led to capture of flies by the ants.
