When do locust eggs hatch?

Answer 1

Plagiarised from 'The Locust Handbook',............. 2.1. 3. INCUBATION PERIOD AND HATCHING The rate at which eggs develop varies according to the soil temperature. The period of egg development, between laying and hatching, is called the INCUBATION PERIOD. The lengths of this period recorded for different areas and seasons are as follows:- Summer breeding in Sudan, Ethiopia and West Africa............................................10 to 14 days Summer breeding in lowlands of India .....................................................................10 to 14 days Summer and winter in Somali Peninsula................................................................... 10 to 14 days Summer and winter on Red Sea Coast.................................................................... 10 to 14 days Spring breeding in central Arabia, southern Iran, Pakistan and North Africa....................................................................................... 25 to 30 days Winter/spring breeding elsewhere in Middle East and in North Africa, in exceptionally cold weather.................................................... 60 to 70 days In warmer weather ..................................................................................................20 to 30 days

Locust eggs must be laid under sand or soil. You need to keep them moist and at a temperature of 30 c. A few drips of water will do most days. It usually takes 2 weeks in optimal conditions, although, if theres not enough water or the temperature is too low, this will take longer.

Answer 3

Mating. The male locust mounts the back of the female, applies the tip of his abdomen to hers and passes sperms into her reproductive tract. The sperms are stored in a sperm sac in the female's abdomen, and as the eggs pass down the oviduct during laying, the sperms are released and so fertilize the eggs.

Eggs. After mating, the female lays her eggs in warm, moist sand following a rainy spell. She pushes her abdomen down into the sand, extending the membranes between the segments, and burrowing to a depth of 50 or 60 mm. In this burrow, 50 to 100 eggs are laid and mixed with a frothy fluid, which hardens slightly and may help to maintain an air supply round the eggs. In 10 to 20 days depending on temperature and moisture, the eggs hatch and the nymphs make their way to the surface and emerge as 'hoppers' (like miniature adults but wingless at this stage).
