The ultrastructure of nymphal dermal pores and the genitalia of adult male of Phenacoccus solenopsis (Hemiptera: Pseudococcidae).

The cotton mealybug, Phenacoccus solenopsis, has established itself as an invasive insect pest worldwide. It causes structural and physiological damage to various crops and can cause substantial financial losses in their production. The successful reproduction of this pest under a wide range of conditions is a key to its success.

A review: application of remote sensing as a promising strategy for insect pests and diseases management.

The present review provides a perspective angle on the historical and cutting-edge strategies of remote sensing techniques and its applications, especially for insect pest and plant disease management. Remote sensing depends on measuring, recording, and processing the electromagnetic radiation reflected and emitted from the ground target. Remote sensing applications depend on the spectral behavior of living organisms.

Insecticidal activity of some wild plant extracts against cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae).

The biological and phytochemical studies of four Egyptian wild plants/weed were studied against Spodoptera littoralis. M. senegalensis had highly significant antifeedant activity on the 3rd instar larvae of S.
