Biologically based new approach for management of cotton key pests in middle Egypt

Abstract |
Cotton in Egypt is subjected to yield and quality losses by arthropod
insects. The Cotton leaf worm (CLW), Spodoptera littoralis and the Cotton
bollworms, pink bollworm (PBW), Pectinophora gossypiella and spiny
bollworm (SBW), Earias insulana cause the greatest part of yield losses
resulted from nearly one million feddans cultivated annually.
The high costs of chemical control, continuing economic losses, secondary
pest problems and environmental considerations suggest the need for
ecologically and biologically oriented cotton pest management strategies.
Extensive research on cotton in Middle Egypt has resulted in a broad array
of monitoring, biological control, cultural, behavioral, genetic and
bioinsecticides that can serve as a base for the formulation of biologicallybased
new approach of integrated management of cotton key pests.
In this paper different ways for use of biological control as a reliable,
environmentally safe means of pest reduction will be illustrated.
Predictive capabilities of Pheromone- based monitoring system, several
simple degree-day models, larval age structure and egg sampling techniques
for forecasting spring emergence patterns and population peaks for cotton
key pests were studied and coupled to a physiologically-based cotton plant
model to examine the insect-plan interactions and timing control
applications . Biological control by preservation and augmentation of
natural enemies as an important component of pest management practices
was involved particularly for Trichogramma species.
Results indicated the cotton key pests could be significantly reduced
through area-wide management approaches. In such case, estimating
economic impact of a biological control program has to be used on a lot of
different indicators including, among others: (1) reduction of the pest
population size, (2) increase in crop yield, (3) increase in production, (4)
increase in farm revenue or receipts, (5) cost saving, (6) increase in product
value, and even (7) social gain (Tesdell, 1990).
In Egypt, four different aspects should be developed for successful
biologically-based management program: (1) Identification of optimal
species and population for a given biological control program, (2)
determine of thermal requirements for parasitoid, pest and host plant, (3)
design of prediction models of the parasitoid and(4) proper timing for
release.
Integrated biologically-based pest management program was formulated
of various biological components of cultural control, natural enemy
preservation and augmentation and timing bio-insecticide-based control
applications by using certain advanced and integrated prediction models of
heat unit, pheromone trap catches, egg sampling and larval age structure.
This program successfully met both of short and long term needs of cotton
pest management in Middle Egypt.
