“…Adult feeding can have important effects on sexspecific mortality rates and sexual behaviour (see also [55]). For example, Pararge aegeria (Satyridae) adults lived longer when fed [56] and in Pseudoplusia includens (Noctuidae), a shortage of food and water led to sex-specific lifespan in a population in which males normally live as long as females [57]. Furthermore, Gotthard et al [56] found in the monandrous P. aegeria a difference in lifespan between males and females when females eclosed synchronously, but no difference when eclosion of females was continuous throughout the year (causing virgin females to be available over a longer period of time).…”

Theory predicts that in monandrous butterfly species males should not invest in a long lifespan because receptive females quickly disappear from the mating population. In polyandrous species, however, it pays for males to invest in longevity, which increases the number of mating opportunities and thus reproductive fitness. We tested an extension of this idea and compared male and female lifespan of two closely related Yponomeuta species with different degree of polyandry. Our results confirmed the theoretical prediction that male lifespan is fine-tuned to female receptive lifespan; once-mated males and females of both polyandrous species had an equal lifespan. However, the degree of polyandry was not reflected in male relative to female lifespan. The observed similar female and male lifespan could largely be attributed to a dramatic reduction of female lifespan after mating.

“…The average time for pre-oviposition ( of eggs was very small when compared to other species of the group, such as P. includens females, which frequently lay more than 500 eggs (Jensen et al 1974) or Autographa precationis (Guenée), which lays 2,000 eggs (Khalsa et al 1979). The nourishment source a 10% honey solution should have been suffi cient, considering that most studies with species of this subfamily successfully used this solution.…”

“…Therefore, we believe the small number of eggs is because the females were not fertilized. Jensen et al (1974) showed that fertilized females, especially with multiple mating, produced more eggs. The failure of fertilization may be related to the presence of only one pair per cage, because in previous experiments evaluating adult diets with only one couple of P. includens per cage, Jensen et al (1974) observed that fewer than 50% of the females were successfully fertilized.…”

Neotropical Entomology 36(1): 001-004 (2007) Aspectos Biológicos de Autoplusia egena (Guenée) (Lepidoptera: Noctuidae, Plusiinae) RESUMO -Autoplusia egena (Guenée) é uma mariposa distribuída em todo continente americano. Suas lagartas alimentam-se de plantas pertencentes a diversas famílias incluindo cultivos de grande importância como soja e feijão. Objetivando contribuir para o conhecimento da sua biologia em laboratório, considerando duração e morfometria de cada fase de desenvolvimento, foi realizada uma criação laboratorial a 25 ± 1°C, 70 ± 10% UR e 14h de fotofase. As lagartas foram alimentadas com folhas de feijão-preto e os adultos com solução de mel a 10%. Os resultados expressos pela média (± EP) para os períodos de cada estágio, em dias, foram: ovo 3,0 ± 0,00; lagarta 15,7 ± 1,25; pré-pupa 1,9 ± 0,05; pupa 8,8 ± 0,09 e adulta: longevidade 12,1 ± 0,95, pré-oviposição 5,4 ± 0,50, oviposição 6,3 ± 1,10 e pós-oviposição 1,4 ± 0,87. As lagartas passaram por cinco ínstares cujos valores médios das larguras das cápsulas cefálicas, em mm foram 0,302 ± 0,001; 0,500 ± 0,003; 0,854 ± 0,008; 1,424 ± 0,011 e 2,744 ± 0,053. As pupas apresentaram comprimento, largura e peso médio de 16,965 ± 0,003 mm, 4,674 ± 0,040 mm e 0,217 ± 0,003 g, respectivamente.PALAVRAS-CHAVE: Desenvolvimento, inseto, morfometria, Phaseolus vulgaris, falsa-medideira ABSTRACT -Autoplusia egena (Guenée) is a moth distributed throughout the Western hemisphere. The larvae have already been found feeding on several different plant families, including important crops such soybeans and beans. To contribute to the knowledge of its biology in laboratory conditions, and considering the duration and the morphometry of each development stage, a laboratorial rearing was accomplished at 25 ± 1°C, 70 ± 10% RH and 14h photophase. The larvae were fed with black bean leaves and the adults were fed with a honey solution at 10%. The results, expressed by the mean (± SE), for the periods of each stage were: egg 3.0 ± 0.00 d; larva 15.7 ± 1.25 d; pre-pupa 1.9 ± 0.05 d; pupa 8.8 ± 0.09 d and adult: longevity 12.1 ± 0.95 d, pre-oviposition 5.4 ± 0.50 d, oviposition 6.3 ± 1.10 d and post-oviposition 1.4 ± 0.87 d. The larvae went through fi ve instars, for which the mean width of the cephalic capsules were 0.302 ± 0.001 mm; 0.500 ± 0.003 mm; 0.854 ± 0.008 mm; 1.424 ± 0.011 mm and 2.744 ± 0.053 mm. The average length, width, and weight of the pupae were 16.965 ± 0.003 mm, 4.674 ± 0.040 mm and 0.217 ± 0.003 g, respectively.

“…Understanding this relationship could be very helpful in predicting the growth response of subsequent generations based on carbohydrate consumption via cotton nectar (Lukefahr and Martin 1964, Jensen et al 1974, Beach et al 1985, Collins and Johnson 1985. Because signiÞcantly more eggs marked with Rb only compared with Cs only were collected from cotton (t ϭ Ϫ2.8520, df ϭ 6, P ϭ 0.0291), adults apparently fed extensively on cotton and subsequently oviposited on this host (Table 6).…”

“…Although this pest is associated with many hosts (Hensley et al 1964, Canerday and Arant 1966, Harding 1976, Martin et al 1976, populations in Mississippi may begin to build early in the growing season on cotton, Gossypium hirsutum L., and later infest neighboring soybean Þelds, as described by Burleigh (1972) in Louisiana cotton and soybean cropping ecosystems. The rapid increase in soybean looper density later in the season is thought to be due to increased fecundity as the result of feeding on cotton nectar, a source of carbohydrates (Lukefahr and Martin 1964, Jensen et al 1974, Beach et al 1985, Collins and Johnson 1985. Although fecundity is increased by adult feeding on cotton nectar, little is known about the actual feeding preference and behavior of the adult soybean looper in cotton and soybean Þelds.…”

Uptake and translocation of the elemental markers rubidium (Rb) and cesium (Cs) within adult soybean looper, Pseudoplusia includens (Walker), were determined using atomic absorption spectrophotometry in the laboratory in various feeding and mating treatments. Neonates were tested to determine marker transfer from male and female adults fed rubidium chloride (RbCl)-treated artificial nectar, cesium chloride (CsCI)-treated artificial nectar, or both. All females contained detectable levels of Rb, Cs, or both, which were obtained either through direct feeding or via spermatophores. Rubidium was present in females at significantly greater levels than Cs. No significant differences in Rb levels were observed between feeding or spermatophore acquisitions. Most neonates had significantly higher levels of Rb than Cs. In a field cage study to evaluate adult feeding and oviposition behavior on blooming cotton and blooming soybean treated with RbCl and CsCl, respectively, more eggs contained Rb than Cs, indicating greater feeding on cotton nectar than soybean nectar, regardless of the host plant upon which eggs were laid. Females laid more eggs on blooming soybean than on blooming cotton. Higher levels of Rb in cotton than Cs in soybean were recorded and may be attributed to initial elemental marker quantities available to the insects. This study provides the support for the generalized observations that soybean looper infestations in soybean can be related to feeding activities by adults in cotton.
