About 470 bird species known from Egypt. The majority are non-breeding migrants, passing through the country, exploiting the wide range of habitat types unique for their life, including agricultural habitats. A survey of wild bird carried out in three agricultural districts, El-Badrasheen, El-Aayyat and El-Hawamdiah districts, in Giza Governorate,...

Pest bird damage in agriculture is a significant and long-standing problem globally especially for high value field crops such as wheat, rice and corn. The present study aims to control the pest birds in the field crops by using sonic waves. The study treatments were sonic waves frequency under four levels of 1, 3, 5, and 7 kHz; exposure time inter...

... The extent and degree of damage is highly variable according to the location and growth stage (Issa, 2018). Quantitative and qualitative damage can reach 60% (Rizk et al., 2020), and crop losses amount to millions of dollars (Anderson et al., 2013). Cereal crops have an important role in global food security and wheat is the most important one (Laskowski et al., 2019). ...
Salama, M.A., M.I. Aamir, A.A. Gh. Farag, M.A. Issa and M.A. Hendawy. 2024. Estimating the Damage of Birds to Wheat, Gurma Melon and Cowpea Crops During the Ripening Period at Sharkia Governorate, Egypt. Arab Journal of Plant Protection, 42(4): 552-557. https://doi. The damage caused by birds to wheat crop is increasing during the ripening stage. The house sparrow, Passer domesticus niloticus is the main bird pest that attacks wheat spikes during the ripening stage (milk, dough, and mature levels) during 2020 and 2021 seasons. The 6 th week of the ripening period suffered the highest damage in all samples compared with other weeks. The samples collected from the field edge showed the highest damage, with 13.05 and 6.75% yield loss during 2020 and 2021, respectively. The samples collected at 6 m from borders didn't show any damage. The statistical analysis indicated that there were significant differences between the tested distances in all weeks of the repining stage during 2020 and 2021 seasons. The gurma melon fruits were attacked by hooded crow, Corvus corone during the ripening stage and the mean proportion of damaged fruits reached 9.47% at the 6 th week of fruit development. The special features of the gurma melon plants made it easy for hooded crows to land and take off, thus the birds attacked the crop at any point in the field, thus there was no significant difference between the fruit damage level and distance from the field border. Cowpea was an attractive crop for many bird species such as pigeons and house sparrows. Birds did attack the cowpea pods during the ripening stage, with 6.97% damage during this stage.

Hassan, A., N. Abo Kaf and E. Mohamed. 2024. Biology of the Citrus Wax Scale Insect, Ceroplastes floridensis Comstock on Citrus Trees, and the Relationship Between the Dimensions of the Developmental Stages of the Insect with its Hosts in Syria. Arab Journal of Plant Protection, 42(4): 419-423. https://doi.org/10.22268/AJPP-001266 This study was carried out during the 2018-2019 period in citrus orchards in Latakia Governorate, Syria. The biology of the citrus wax scale, Ceroplastes floridensis Comstock (Homoptera: Coccidae), was investigated and the effect of the plant host on the insect stages dimensions was determined. It has been shown that the insect had two generations per year, and the adult female laid an average of 350-500 eggs under a wax cover. The dimensions of the insect’s stages reached their highest value on the laurel plant, followed by loquat, and the least was on citrus. Keywords: Citrus wax scale, Ceroplastes floridensis, Syria.
Ecologically, the presence of avifauna is a crucial indicator of ecosystem
equilibrium. The diversity of bird species and their community structure serves
as an essential tool for assessing ecological impacts. This study aimed to
evaluate the species composition, evenness, and diversity of wild bird species
across different habitats in Egypt from May 2023 to February 2024. The study
identified 17,387 individuals from 40 resident bird species belonging to 25
families and 10 orders. The house sparrow exhibited the highest relative
abundance among resident bird species, followed by the western cattle egret,
barn swallow, house crow, rock pigeon, little egret, hooded crow, laughing
dove, and common myna. In terms of migratory birds, 6,050 individuals from
39 species across 22 families and 11 orders were observed. The slender-billed
gull, little stint, great cormorant, common ringed plover, the European bee-
eater, black-winged stilt, and white wagtail had the highest relative abundances
among migratory species. The distribution of bird species across different sites
revealed that the coastal area (CA) and the Suez Canal & Gulf Suez (SCGS)
each harbored 25% of the total number of resident species, followed by the Nile
Delta (ND) with 21%, the Nile Valley (NV) with 16%, and the Faiyum (F) area
with 13%. For migratory birds, the CA accounted for 48% of all migratory
species, followed by the F area at 23%, ND at 13%, SCGS at 11%, and NV at
5%. The highest species richness was recorded in the CA, followed by SCGS,
ND, F, and NV. The highest values for the Shannon and Simpson indices were
found in the CA, NV, ND, SCGS, and F areas, respectively. It can be concluded
that the Egyptian environment, especially aquatic habitats, is a valuable
resource for the Egyptian avifauna by providing food sources and nesting site
