Food quality effects on instar‐specific life histories of a holometabolous insect

“…For example, third and fourth instar larvae across taxa typically consume between 90% and 180%, respectively, more food than younger first and second instars (Barrigossi, Zimmermann, & Lima, 2002;Santos, Almeida, Castro-Guedes, & Penteado, 2014), and therefore, the negative effects of consuming poor food quality might not be as evident in younger instar stages compared with older stages simply because they have not consumed enough of it. However, as animals grew and progressed through their instars, we found larger effects of pellet quality on growth and development F I G U R E 3 Fitted stage-structured model to time-series data comprising the number of Callosobruchus maculatus in a particular stage of development (1st, 2nd, 3rd, and 4th instar, pupal and adult) through time (left), and the cumulative number of C. maculatus that died in each stage of development (right) for each pellet quality (90% black-eye pea: 10% filler, 95% black-eye pea: 5% filler, and 100% black-eye pea: 0% filler).…”

“…This disparity in food quality effects on growth and development between earlier and later instars could be an artifact of the amount of food consumed, where the more food that is consumed, the more apparent the effects are on the consumer. For example, third and fourth instar larvae across taxa typically consume between 90% and 180%, respectively, more food than younger first and second instars (Barrigossi, Zimmermann, & Lima, 2002;Santos, Almeida, Castro-Guedes, & Penteado, 2014), and therefore, the negative effects of consuming poor food quality might not be as evident in younger instar stages compared with older stages simply because they have not consumed enough of it.…”

Behavioral and Immunological Features Promoting the Invasive Performance of the Harlequin Ladybird Harmonia axyridis

“…It is an excellent example of an efficient invasive species, being one of the most abundant ladybird species in various agricultural ecosystems including corn, soybean, wheat, corn, broad bean, potato, and cotton (Gardiner et al, 2011;Vandereycken et al, 2013a,b). H. axyridis is highly fertile and the eggs show high viability (Santos et al, 2014). Multi-year surveys have documented the decline of native coccinellid species in concert with the establishment of H. axyridis (e.g., Bahlai et al, 2015).…”

Survival and Reproduction ofChrysoperla carnea(Stephens)1Fed Different Diets

“…Santos et al (2014) said eggs were better, because fourth-instar larvae of Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) fed their own eggs reached the adult stage in less time. They also considered that for an effective biological control agent, r m must be equal or greater than that of its prey, which favors establishment of the natural enemy.…”
