Journal ArticleDOI
Insektenwanderung und Luftströmung1
TL;DR: The main principles of insect-migration over greater distances are the direction of the flight very often coincides with that of the wind and the insects compensate sidewinds by turning their bodies in order to regulate thedirection of their flight.

Effect of fluctuating temperatures on development, reproduction and energy of oriental armyworm populations, Mythimna separata
Wei-Sheng Lv,Xingcheng Xie +1 more
TL;DR: In this paper , the effects of fluctuating environmental conditions on M. separata populations remain poorly understood, and the authors investigated how fluctuating temperatures affect the development, reproduction, flight capacity and energy reserves of both migrant and resident populations of both species.
Population Dynamics of Mosquitoes
Stephen M Smith,Charles Elton +1 more
TL;DR: Both approaches evaluate ageor stage-specific variables but neither may provide deep insights into the mechanisms that cause the variations in survivorship or natality in populations.
Dissertation
The biology and ecology of Aleyrodes proletella, the Cabbage Whitefly : a pest of Brassica crops
TL;DR: The overall aim of this project is to understand population trends of A. proletella in the most vulnerable crops, Brussels sprout and kale, which includes understanding the key times of population increase and colonisation of new crops.

A Novel Method for Estimating the Pre-Reproductive Period of Female African Armyworm Moths, Spodoptera Exempta
TL;DR: A novel method for estimating the PRP of Spodoptera exempta (Walker) (Lepidoptera: Noctuidae) relies on the fact that as the female approaches sexual maturity, there is a substantial change in the shape of her gonopore-patch (an area of black scales at the posterior of the abdomen).

Studies on the Feeding and Nutrition of Tuberolachnus Salignus (Gmelin) (Homoptera, Aphididae)
TL;DR: In this paper, the sugar and nitrogen composition of the phloem sieve-tube sap ingested by Tuberolachnus salignus (Gmelin) feeding on Salix acutifolia stems, and the honeydew excreted by the aphids was investigated.
