1. The permeability of perfused intimal sacs to fourteen non-ionic, hydrophilic molecules of graded molecular size was estimated by radioisotope flux. 2. The rectal cuticle acts as a molecular sieve severely restricting the rate of penetration of molecules with increasing hydrated size. 3. The penetration of test molecules was as predicted by the Renkin equation for a uniform population of water-filled pores having radii of 6.5 Å. 4. The properties of cuticles from the rectum and the integument are compared and the role of the rectal intima in the excretory process in the desert locust is discussed.

Insight Into

The recent upsurge of the desert locust Schistocerca gregaria (Forskål, 1775) has had an impact on East Africa and the Middle East as far as India. It has affected and slowed down many aspects of the Pakistani economy. Swarms of locusts have infested many areas and caused immense damage to all types of crops. Both farmers and economists are concerned and are trying to get the most up-to-date information on the best strategy to manage this pest. This paper is an attempt to (i) provide insight into the dynamics of this upsurge internationally as well as in the various regions of Pakistan, (ii) briefly assess its local impact and locust control measures, and (iii) clarify the role of the various stakeholders in the management, both nationally and internationally, suggesting various improvements for the future.

New Evidence

New evidence on the nature of recession populations of the desert locust, Schistocerca gregaria (Forsk.), and on the nature and role of its outbreaks is presented. It is shown that the hopper bands and swarms reported during the 1963–67 recession differed qualitatively and quantitatively from those characteristic of plague periods and were numerically much smaller than some low density non-swarming populations. Gregarisation frequently occurs in the latter and may be on a scale sufficient to give rise to an outbreak; in turn outbreaks may lead to plague upsurges.
