Abstract

The surveyed arthropods on soybean plants and polyculture of soybean and
ma
ize at two locations representing Middle Egypt revealed the presence of 117 insect
specie
s belonging 10 58 fOlrr.iiies from 11 orders (of which 9 species of order
Orthoptera belongi
ng to 4 families). classified as 44 phytophagous species of
econom
ic importance (37.0%) and 33 insec1 sp < /span>ecies as visitors. pollinators. non-pest
and saprophagous
(28.0%). However. natural enemies (predators and parasites) were
presented by 40 species
(35.0%) and Acarina by 4 species (2 of them were classified
as phytophagous m
ites and the others as predators). In maizelsoybean intercropping
systems
. maize is infested mosUy with the same pests. where a partial taxonomic list
shows that the
insect fauna consists of 43 famiQes from 11 orders in addition to mites
(3 families)
: pest species were classified as: 9 species as foliage feeders, 3 as stem
bo
rers. 2 as root feeders. 5 as ear feeders. 1 as leaf miner, 10 as sap-suckers and 22
as natural enemies (13 predators and 9 paras
ites). Four species of Acarina belonging
to 3 famil
ies (2 phytophagous and 2 predators).
