Multiple Mating and Its Effect on Female Reproductive Output in the Bean Bug Reptortus clavatus (Heteroptera: Alydidae) [Elektronische Daten] [Tamito Sakurai] Multiple mating and its effects on fecundity and fertility in the female bean bug Reptortus clavatus (Thunberg) were investigated under laboratory conditions. Multiply mated females showed higher fecundity and fertility than singly mated females, suggesting that natural selection may favor multiple mating in R. clavatus females. However, females were unwilling to remate for 15—20 d after 1st mating, indicating that remating may be costly to females. Nearly 50% (24/50) of singly mated females exhausted most sperm from their seminal receptacles (spermathecae) by 28 d after beginning to oviposit and began laying infertile eggs, but their fertility recovered after remating. These results support the hypothesis that females remate to replenish an inadequate sperm supply if absence of stored sperm outweighs the cost of remating in terms of higher productivity. © 1996 Entomological Society of America Behavior nationallicence Reptortus clavatus nationallicence multiple mating nationallicence reproductive output nationallicence refractory period nationallicence sperm supply nationallicence Annals of the Entomological Society of America Oxford University Press 89/3(1996-05-01), 481-485 0013-8746 89:3<481 1996 89 aesa https://doi.org/10.1093/aesa/89.3.481 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/aesa/89.3.481 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Sakurai Tamito Laboratory of Applied Entomology, School of Agricultural Sciences, Nagoya University, Chikusa, Nagoya 464-01, Japan NATIONALLICENCE 773 0- Annals of the Entomological Society of America Oxford University Press 89/3(1996-05-01), 481-485 0013-8746 89:3<481 1996 89 aesa Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
