Abstract
Legumes are eharacterized by the high protein content
and nutritive value of their seeds in addition to the roots
possessing nodules containing rhizobia that are capable of
fixing n1trogen. The work in thi s Thesi s carried out in
the Experimental farm, Sids region, Beni-Suef’ Governorate.
during the two successive seasons of 1984/85 and 1985/S6
included stUdies on the insects associated with five
leguminous crops; broad bean, fenugreek, chickpea, lentil
and lupin. Results could be divided into 4 main parts
and may be summarized as follows :
I. Survey studies:
By early December 1984, quarter monthly samples were
obtained by 30 double strokes of an insect sweeping net
and manual inspection of five plants/plot. Sampling took
place until May, 10th. The cs,pturedlnsects were killed,
identified and counted. The survey of insects revealed
the presence of 85 species belonging to 34 families and
9 orders.
1.1. Paba bean insects:
A :number of ’16 species belonging to 34 families and
8 orders were surveyed on taba bean plants. Twelve of
these species were found as toliage feeders. 12 sap
suckers, 2 leaf-miners, 5 ted on seede, 13, predators and
Z 12 paras! tes. Surveyed insect species included also
the bee honey and 2 other pollinators. In addition to
these species,l’” species were also surveyed, but they
were found in very low numbers.
1.2. Fenugreek insec~s :
A total of 59 insect species belonging to 32 fami1iee
and 9 orders were surveyed on fenugreek plants. Fromthese
species 7 species were found as foliage feeders, 10 fed
I
on the plant sap, 2 lest miners, 4. fed on seeds, 10 insect
predators and 1.2were found as insect parseil-es. In .
addition to these species, 13 were also surveyed, but
individuals of these species were found of very low
occurrence.
I.). Chickpea insects:
Fifty- two insect species belonging to 26 families fron:
9 orders could be surveyed on ch1ek~ea plants. These insect
species included 1’- pest species of which» were found as
toliage feeders. 7 ted on the plant sap, ) fed on the
seeds, and 2 were .found as leat-m1~rs. The beneficial.
insect species surveyed on chickpea Iplants included 2
,
pollinators, and t predaceous and 9 I parasitic insect
!
species. Besides, 16 insect speCier were surveyed, but
in very low numbers on chickpea plants. Those includeO
4 lepidopteran,_6 ~pt.~, ._~eteropteran :an4 2
coleopteran 108ect81.4. Lentil insects:
A total number of 51 insect species belonging to 27
families from 9 orders could be ’surveyed trom lentil
fields. from these spacies~21 were found as pests on
len~il plants. Those included 6 species that fed on the
plant foliage, 11 sap Buckers, 2 leaf-miners and 2 red on
the/crop seeds. Nine insect predators and 8 parasitic
species were also surveyed on lentil plants, while ’3 speciel
were surveyed as pollinators. Beside to these species,
other 10 insect species were found in very low num~ers.
Those included 2 heteropterous.6 homopterous, aud two

1.5. Lupin insects :
Fourty- :tour insect species belonging to 22 families
and 8 orders could be surveyed on lupin plants throughout
the two successive seasons 1984/85 aI),d 1985/86. These
species inclUded I 5 pest species of .hieh) were foliage
feeders, 10 sap suckers and 2 fed on the seeds. On the
other hand, benefieial insects inc1uQed 10 predators,
5 parasites and 3 pollinators. In addition to these species,
other 11 insect species could be surveyed but in very low
•
numbers. from these species, 3 belonged to Heteroptera
and 6 to Homoptera, in addition to one lepidopteran, one
coleopterap and two dipteran species.
