Evaluation of Artemia sp. (Branchiopoda, Artemiidae) as an alternative prey for laboratory rearing of Tupiocoris cucurbitaceus (Hemiptera: Miridae), a predator of horticultural pests

“…This fertility peak was previously found for T. cucurbitaceus preying on T. absoluta and S. cerealella eggs (Cagnotti et al, 2021). However, this result does not agree with that of Burla et al (2014) who registered the highest nymph production during the first, second and third weeks of female lifespan of T. cucurbitaceus fed on E. kuehniella eggs. We also observed that T. cucurbitaceus females laid off spring in the first 4 days of their lifespan, regardless of the diet evaluated.…”

“…More than 60 % died regardless the prey on which they had fed. This value was higher than the reported by Burla et al (2014) for the same mirid on tobacco plants after feeding on E. kuehniella eggs. Neverthless, the mortality values here registered were similar (Grenier et al, 1989;Vandekerkhove et al, 2008;Labbé et al, 2018) or higher than the recorded for other mirids fed on Artemia sp.…”

“…There were no significant differences in the developmental time of F0 nymphs among diets (K-W= 3.22, df= 28, P= 0.20) (Table 1), reaching the adulthood after 11 to 13 days. This value was slightly lower than those recorded for this predator feeding on S. cerealella eggs (López et al, 2012), B. tabaci nymphs (Orozco Muñoz et al, 2012 and E. kuehniella eggs (Burla et al, 2014). Neither did other authors find differences in the developmental time of other mirid species, such as M. pygmaeus (Castañé et al, 2006) and Dicyphus hesperus (Knight) (Miridae) (Labbé et al, 2018) when they used Artemia sp.…”

Heterópteros míridos depredadores de trialeurodes vaporariorum (Westwood), en particular tupiocoris cucurbitaceus (Spinola) observado en Chile central

“…(2012) este depredador tuvo un periodo de míridos de 24,3 ± 1,5 d para hembras y 23,7 ± 0,6 d para machos en ambos cultivos usando B. tabaci. De acuerdo a Burla et al (2014), el alto consumo de huevos de T. vaporariorum por parte de T. cucurbitaceus sugiere la necesidad de llevar a cabo nuevos estudios para incluir este depredador en programas de control biológico en invernaderos.…”
