Species founds in Europe, Central Africa, Madagascar, Central and South-Eastern Asia, Australia.
The adult body is grayish-green colored, with dark spots on the head and front wings and the body length ranges 30-55 mm.
The egg is 5-7 mm long, reddish-yellow colored. The pods are cylindric, slightly curves, 50-70 mm long and contain 50-100 eggs, disposed on rows of 4 eggs each.
The larva goes through different larval instars and its body is 7-10 up to 30-40 mm long.
Biology and ecology:
It forms one generation per year and overwinters as an egg in a pod, laid in the soil in autumn, at various depths. The larvae form in spring, in the second decade of May, when the soil temperature is 19-21º C, and the air temperature is 14-15º C. At about 30 days after complete development, sexual maturity takes place, after which, adults mate.
After copulation, females lay 200-300 eggs, in 3-5 pods, in sandy soils, 3-6 cm deep in the soil.
The locust migration takes place in warm days, with temperature of 21-23º C. During the outbreak periods, the formation of flocks of locusts is caused by temperature, luminosity, wind and food.
Damaged Plants and Damage:
It is a polyphagous species, which prefers as plants cereals, cane, beetroot, clover, sunflower, Gramineae etc.
It attacks the aerial parts of the plants, and during outbreaks, they can destroy crops, leaving intact just the think and hard stems. The most severe damage is caused in areas with cane and corn.
