Fecundity, fertility, and developmental stage survivorship of Eretmapodites quinquevittatus

Abstract

This laboratory study analyzed fecundity, fertility (percentage hatched), and developmental stage survivorship of Eretmapodites quinquevittatus. Fecundity for females averaged 190.4 eggs, whereas paired (one male/female pair) females averaged 100.5 eggs. Fertility for autogenous eggs from paired females was 84.4%, which was significantly greater than percentage hatched of anautogenous eggs (67.3%). Percentage hatched of autogenous eggs from experimental groups (25 males/25 females) was 87.8%, whereas percentage hatched of anautogenous eggs was 74.5%. Developmental stage survivorship was significantly different for every stage of development of progeny from autogenous eggs, except the egg stage, when comparing experimental groups with pairs. Developmental stage survivorship of progeny from anautogenous eggs was significantly different only at the egg stage and 1st instar when comparing experimental groups and pairs.
