Exempel på hur man kan använda OOTHECA i en mening

• The production of ootheca convergently evolved across numerous insect species due to a selection for protection from parasites and other forms of predation, as the complex structure of the shell casing provides an evolutionary reproductive advantage (although the fitness and lifespan also depend on other factors such as the temperature of the incubating ootheca).
• Females can oviposit an average of 10 or more oothecae in favorable environments, but this is highly dependent on the cockroaches' body fat, thereby as her body mass decreases fewer ootheca are oviposited in a season.
• Some are able to oviposit even when the female cockroach still carries the fresh ootheca around, while other ensign wasps will only attack oothecae that are completed and have been dropped by the mother roach.
• They generally resemble cockroaches, but most members, unlike modern dictyopterans, have generally long external ovipositors, and are thought not to have laid ootheca like modern dictyopterans.
• This species is falsely ovoviviparous; the female extrudes the ootheca from its brood sac but does not deposit it.
• The cumulative effect of several generations of parasitoid wasps on ootheca are estimated to cause over 30% loss of developing mantids and there is a clear negative correlation between parasitoid burden and mantid enclosure.
