Immature mating as a tactic of polygynous male western widow spiders
Die Naturwissenschaften, 2020In polygynous species, males typically mate with more than one female, and male investment in any one mating should decrease if securing that mating reduces future mating opportunities. In contrast, monogynous males mate only once, so they should invest maximally in that single mating.

Abstract A series of experiments was conducted to investigate whether temperatures of 18 °C, 25 °C, 30 °C, and 35 °C and a photoperiod of 16L:8D at immature and adult stages would differentially affect the mating duration and egg production of Neoseiulus californicus females mated once.

When 6-day-old (immature) pupae of Ceratitis capitata (Wiedemann) were irradiated in nitrogen with doses of 10, 12, or 14 krad, the males had a higher level of sterility than males irradiated in nitrogen as 9-day-old (mature) pupae with 14 krad. However, sexual competitiveness, ability to inseminate females, and production of sex pheromones to attract ...

Aggressive male mating behavior depends on female maturity in Octopus bimaculoides
Marine Biology, 2014 This laboratory study examined the combined effects of male and female behaviors on the outcome of mating encounters in Octopus bimaculoides. We found that male-male competition for mating opportunities depends on female maturity; the presence of ...

Mating scars reveal mate size in immature female blue shark Prionace glauca
Journal of Fish Biology, 2015The objective of this study was to determine the size and maturity status of the male blue sharks Prionace glauca attempting to mate with small, immature females in the north‐west Atlantic Ocean. The relationship between male curved fork length (LFC) and jaw gape was used in conjunction with the diameter of the mating scar to estimate the LFC and infer

Host plants and immatures as mate-searching cues in Heliconius butterflies
Animal Behaviour, 2010The study of interactions between phytophagous insects and their host plants extends beyond understanding how insects deal with plant chemical defences. Sexual behaviour of these herbivores is integrated in several ways with host plants, as the latter influence timing and location of reproduction, and can provide clues for finding mates.

Forward genetics approaches have helped elucidate the anthocyanin biosynthetic pathway in plants. Here, we used the Arabidopsis banyuls (ban) mutant, which accumulates anthocyanins, instead of colorless proanthocyanidin precursors, in immature seeds. In contrast to standard screens for mutants lacking anthocyanins in leaves/stems, we mutagenized ban ...

AbstractRaspberry ketone (RK) dietary supplements accelerate the emergence of sexual behaviour in developing Queensland fruit fly (Q‐fly) males and show promise as a pre‐release supplement for use in sterile insect technique (SIT) programs. However, the value of RK supplements in SIT programs would be greatly reduced if RK‐treated males are ineffective
