Neonate larval survival of European corn borers, Ostrinia nubilalis, on high and low dimboa genotypes of maize: Effects of light intensity and degree of insect inbreeding

Effect of Maize Lines on Larval Fitness Costs of Cry1F Resistance in the European Corn Borer (Lepidoptera: Crambidae)

“…DIMBOA provides host plant resistance against O. nubilalis through antibiosis (Sullivan et al 1974, Abel et al 2000. In both experiments, survival was highest on WF9, which has low levels of DIMBOA and is often used as a susceptible control in experiments with O. nubilalis (Sullivan et al 1974, Manuwoto andScriber 1985). Developmental rate was slowest on B94, which may be explained by the moderate DIMBOA-mediated resistance to O. nubilalis for this maize line (Russell 1991, Abel et al 2000.…”

“…Maize plants were grown in a greenhouse in a soil mixture composed of equal volumes of two types of soil mixtures (Sunshine Mix #1/LC1 and MetroMix 900, Sun Gro Horticulture, Vancouver, BC, Canada) in 9-liter pots (Classic 1000, Hummert International, Earth City, MO). Supplemental lighting was supplied with 400 W high-pressure sodium bulbs (Ruud Lighting Inc., Racine, WI) with a photoperiod (Manuwoto andScriber 1985, Klenke et al 1986). The maize line B94 has moderate levels of DIMBOA, which confers resistance against O. nubilalis (Russell 1991, Abel et al 2000.…”

The mortality of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) neonate larvae in relation to drop‐off and soil surface temperature: the dangers of bungy jumping

“…the suitability of hosts (Miller et al 1991;Cockfield & Mahr 1993), nutrition and plant effects (Farrell et al 1991;English-Loeb et al 1997), microclimate (Manuwoto & Scriber 1985) and the presence of predators (Bernays 1997;Stamp & Bowers 2000). While the success of larvae does depend on their ability to establish on a host plant, the act of finding and moving within and between plants may be pivotal to mortality rate of neonate larvae (Terry et al 1989).…”

Light intensity and wavelength influence development, reproduction and locomotor activity in the predatory flower bug Orius sauteri (Poppius) (Hemiptera: Anthocoridae)

“…In particular, light intensity and wavelength are known to influence biological and physiological processes in insects (Bishop 1969;Manuwoto and Scriber 1985;Sakai et al 2002). Predators and parasitoids have received substantial attention in this regard because of the need to understand photic influences on biological control outcomes (e.g., Omkar et al 2005;Malaquias et al 2010) and the suitability of lighting regimes for mass rearing natural enemies for augmentative biological control applications (Chambers 1977).…”
