As noted above, ovipositions
by single pairs were more common at Pond 1 than ovipositions
The matings took place throughout May and ovipositions
followed within about two weeks of the last mating (depending on weather conditions; Olsson et al.
None of the apparent parasitoid ovipositions
yielded any development to larvae.
Among females known to have mated only once (n = 84), the number of viable eggs correlated positively with the duration of mating and with the age of the female at the time of fertilization and decreased significantly with successive ovipositions
I classified females that spread their ovipositions
more evenly as "neutral.
Parasitoid females at Summerland oviposited more often into SF mines in the fall generation of 1991 (proportion of ovipositions
on SF larvae: third generation 52%; Table 1), than in the two summer generations of 1991 (proportion of ovipositions
on SF larvae: first generation 0%, second generation 5%; R.
the time period for most ovipositions
under field conditions (Aluja et al.
One possible reason for its success lies in its fecundity, as it can produce an egg sac every four days during its earliest ovipositions
and averages 22 egg sacs in a lifetime (Bouillon and Lekie 1961).
Number of eggs and ovipositions
(mean [+ or -] standard deviation) of Spodoptera frugiperda (Lepidoptera: Noctuidae) on different cotton varieties with and without free choice tests.
ne](x)] where In is the expression for "natural logarithm" roughly proportional to the random number NO that represents the total number of ovipositions
in the period.
Continuous recording (sensu Martin & Bateson 1993) was made of all relevant behavioral events such as fights between males, copulations, and ovipositions
were characterized by a Karner blue crawling down a lupine stem, flexing its abdomen, and depositing an egg.
