“…Parker (1930) recorded one caged female which laid 15 egg pods, and the average for 30 females observed by him was 8.8 pods. Other data on egg production were presented by Pfadt (1949) and Smith, Handford, and Chefurka (1952). In laboratory cages, using material from central Saskatchewan, Pickford (Shotwell, 1930, p. 23) and the location.…”

GRASSHOPPERS-GURNEY AND BROOKS 5The male genital mass or assemblage, preferably known as the phallic complex, including the aedeagus and its supporting apodemes, as well as the epiphallus-located anterior to the aedeagus ( fig. 2,6) is situated at the end of the abdomen beneath the supra-anal plate and the pallium (membranous covering usually dorsad of the subgenital plate). Taxonomically, the aedeagus and epiphallus are the most important organs of the phallic complex, and the critical parts of each are illustrated by M. femur-rubrum ( fig. l,h,i

“…Such plants may have provided both moisture and the necessary requirements for oviposition and food, although Smith et al (1952) and Pickford (1962) demonstrated that M. sanguinipes survived poorly and produced few egg pods if S. kali was the only food. sangztinipes laid its eggs qenerally throughout the fields, but more eggs were found on drift ridges at the k e~d margins, particularly on the warmer slopes facing south and west.…”

“…Survival was highest and nymphal developmental rates fastest when Melanoplus sanguinipes (Fabricius) and Camnula pellucida Scudder were provided a straight or mixed diet of winter wheat (Triticum aestivium L.) or Hordeum vulgare L. and weeds as opposed to western wheatgrass (Agropyron smithii Rydb.) (Pfadt 1949;Smith et al 1952;Pickford 1958Pickford , 1962Pickford , 1963Reigert et al 1965). In similar studies both species experienced poorer survival and slower developmental rates on diets composed exclusively of native plants versus those fed a combination of wheat and weeds (Putnam 1962;Pickford 1963).…”

The Canadian Entomologist 126: 1263-1275 (1994) Temperature-dependent development of eggs, larvae, and pupae of the speckled green fruitworm, Orthosia hibisci Guenke, at constant temperatures of 5-30. 0°C, 7.5-27.S0C, and 0.8-20.g°C, respectively, was described. Development times decreased with increasing temperatures and minimum developmental times in eggs, larvae, and pupae occurred at ca. 27.5,25, and 20.8"C, respectively. Variation in development times of all life stages was modelled accurately (R2 values 0.98-0.99) with a Weibull distribution. Relationships between temperature and developmental rates of all life stages were described by linear degree-day (DD) and nonlinear poikilotherm models.
