Abstract

The influence of soil moisture and temperature on hatchling weight during the solitary phase of Locusta migratoria migratorioides (Reiche and Fairmaire) was studied. Soil moisture is an important weight determining factor; heavier hatchlings are produced in relatively wetter soils. Temperature has no apparent influence on hatchling weight. Hatchling weight and hatchling survival to the second instar showed a positive significant correlation.

Résumé

L’influence de l’humidité du sol et de la température sur le poids des larves pendant la phase solitaire de Locusta migratoria migratorioides (Reiche et Fairmaire) a été étudiée. L’humidité du sol s’est revélée un important facteur déterminant; les larves pesant plus lourdes sont observées dans les sols relativement plus humides. La température n’a aucune influence apparente sur le poids des larves. La relation entre le poids des larves et leur survie jusqu’a stade 2 larvaire a été aussi examinée. Il y a un important rapport entre les deux parametres.
