Abstract The current study was carried out to estimate the prevalence and diversity of ectoparasites in rock pigeons in different regions of Punjab, Pakistan. A total of 120 birds were captured from March 2017 to February 2019. The ectoparasites were collected by standard procedures and preserved in 70\% ethanol containing one drop of glycerin. Data related to age, health status, sex, type of area, sampling location and season were collected using a standardized form. Ectoparasites were identified based on morphological characteristics by using identification keys. Ninety-six (80\%) birds were infested with ectoparasites. A total of seven families and thirteen species of different ectoparasites were observed. Mainly, seven species of lice, two species of flies, one species of tick and three species of mites were recovered from infested birds. The female pigeons were more often infested (89.02\%) than male pigeons (60.52\%). The prevalence was found higher during summer (100\%) as compared to other seasons. The infestation rate was higher in Industrial area (97.50\%) as compared to other regions. The highest prevalence of ectoparasites (100\%) was recorded from Sargodha district. There was significant (P \< 0.05) variation among number of ectoparasites on wing, chest, tail and neck within age groups, seasons and ecological zones. The occurrence of parasites in relation to area, age, health status, sex and season were significant. The infestation rate of parasites in rock pigeon is high in different districts of Punjab. It is recommended that these wild birds infested with multiple species of ectoparasites could be the potential source of infestations in domesticated birds if they come in contact with them. The contact of domesticated birds should be prevented from wild birds to minimize the chance of cross species transmission of ectoparasites.

Resumo
O presente estudo foi realizado para estimar a preval\ência e diversidade de ectoparasitas em pombos-das-rochas em diferentes regi\ões de Punjab, Paquist\ão. Um total de 120 aves foram capturadas de mar\ço de 2017 a fevereiro de 2019. Os ectoparasitas foram coletados por procedimentos padr\ão e preservados em etanol 70\% contendo uma gota de glicerina. Os dados relativos \à idade, estado de sa\úde, sexo, tipo de \área, local de amostragem e \época do ano foram coletados em formul\ário padronizado. Os ectoparasitas foram identificados com base nas caracter\ísticas morfol\ógicas por meio de chaves de identifica\ç\ão. Noventa e seis (80\%) aves estavam infestadas com ectoparasitas. Um total de sete fam\ílias e treze esp\écies de diferentes ectoparasitas foram observados. Principalmente, sete esp\écies de piolhos, duas esp\écies de moscas, uma esp\écie de carrapato e tr\ês esp\écies de \ácaros foram recuperadas de aves
infestadas. Os pombos f\êmeas foram infestados mais frequentemente (89,02\%) do que os pombos machos (60,52\%). A preval\ência encontrada foi maior no ver\ão (100\%) em compara\ç\ão com as outras esta\ç\ões. A taxa de infesta\ç\ão foi maior na \área Industrial (97,50\%) em rela\ç\ão \às demais regi\ões. A maior preval\ência de ectoparasitas (100\%) foi registrada no distrito de Sargodha. Houve varia\ç\ão significativa (P \<0,05) entre o n\úmero de ectoparasitas na asa,
t\órax, cauda e pesco\ço dentro das faixas et\árias, esta\ç\ões do ano e zonas ecol\ógicas. A ocorr\ência de parasitas em rela\ç\ão \à \área, idade, estado de sa\úde, sexo e esta\ç\ão do ano foi significativa. A taxa de infesta\ç\ão de parasitas em pombo-correio \é alta em diferentes distritos de Punjab. Recomenda-se que essas aves selvagens infestadas com v\árias esp\écies de ectoparasitas possam ser a fonte potencial de infesta\ç\ões em aves domesticadas se entrarem em
contato com elas. O contato de aves domesticadas deve ser evitado com aves selvagens para minimizar a chance de transmiss\ão cruzada de ectoparasitas.

Abstract: This study was carried out in South-eastern Algerian Oases for two years (2017 and 2018) on 300 doves consisting of two species, Streptopelia turtur arenicola L. and Streptopelia decaocto (Frivaldszky, 1838). A total of 854 ectoparasite specimens were identified. On Streptopelia decaocto, five lice species recorded for the first time in Biskra (Algeria) were detected and the population was dominated by Columbicola bacillus (82.67\% \± 3.92) followed by Coloceras piageti (22\% \± 3.35), Hohorsteilla spp (9.33\% \± 2.93), Hohorstiella modesta (8\% \± 2.66), and Bonomiella concii (3.33\% \± 3.12). Other orders such us Diptera (flies) were represented by Pseudolynchia canariensis (4.67\% \± 1.72), Ixodida (ticks) by Argas spp (20.09\% \± 1.91) and Mesostigmata (mites) by two species Dermanyssus spp (5.35\% \± 1.59) and Ornithonyssus bacoti (1.94 \± 1.28). On S. turtur, two lice species were recorded Columbicola bacillus (85.47\% \± 2.76) and Coloceras britannicum (28.67\% \± 4.07). Ticks and mites were represented, respectively, by Argas spp (13.66\% \± 2.85) and Dermanyssus spp (2 \% \± 1.18). Higher prevalence of a single infestation was observed on S. decaocto (50\%), compared with double (36.66\%), triple (9.33\%) and quadruple (1.33\%) infestations. However, the difference between single and mixed infestations on males and females was statistically significant (p \< 0.05). On the other hand, S. turtur had higher prevalence of single infestations (68.67\%), compared with double (26.67\%) and triple\  infestations (4.67\%), the difference in the prevalence of single and mixed infestation was not statistically significant (p \> 0.05). The young chicks of the two dove species were not infested.

R\ésum\é Cette \étude a \ét\é r\éalis\ée dans les oasis du Sud-Est Alg\érien de la wilaya de Biskra durant la p\ériode 2017-2018. Sur 300 individus de tourterelles constitu\ées de deux esp\èces Streptopelia turtur arenicola L. et Streptopelia decaocto (Frivaldszky, 1838), un total de 854 sp\écimens d\’ectoparasites a \ét\é trouv\é. Concernant Streptopelia decaocto, cinq esp\èces de poux ont \ét\é pr\élev\ées et identifi\ées pour la premi\ère fois. Ces poux \étaient domin\és par Columbicola bacillus avec (82,67 \% \± 3,9 2) suivi par Coloceraspiageti (22 \% \± 3,35), Hohor stiella spp (9,33 \% \± 2,93), Hohorstiella modesta (8 \% \± 2,66) et Bonomiellaconcii (3,33 \% \± 3,12). Cependant, l\’ordre des Diptera (mouches) est repr\ésent\é par Pseudolynchiacanariensis avec (4,67 \% \± 1,72), celui des Ixodida (tiques) par Argas spp avec (20,09 \% \± 1,91) et celui des Mesostigmata (acariens) par deux esp\èces Dermanyssus spp avec (5,35 \% \± 1,59) et Ornithonyssus bacoti avec (1,94 \% \± 1,28). Concernant S. turtur, deux esp\èces de poux ont \ét\é enregistr\ées Columbicola bacillus avec (85,47 \% \± 2,76) et Coloceras britannicum avec (28,67 \% \± 4,07). Les tiques et les acariens \étaient repr\ésent\és respectivement par Argas spp (13,66 \% \± 2,85) et Dermanyssus spp (2 \% \± 1,18). La pr\évalence la plus \élev\ée d\&$\#$39;infestation unique a \ét\é observ\ée sur S. decaocto (50 \%), par rapport aux infestations doubles (36,66 \%), triples (9,33 \%) et quadruples (1,33 \%). Cependant, la diff\érence d\’infestation unique et mixte entre les m\âles et les femelles \était statistiquement significative (p \<0, 05), alors que pour S. turtur, la pr\évalence d\&$\#$39;infestations uniques \était plus \élev\ée avec (68,67 \%), par rapport aux doubles (26,67 \%) et triples infestations (4,67 \%), sachant que la comparaison de cette pr\évalence d\&$\#$39;infestation unique et mixte entre les deux sexes est statistiquement non significative (p \> 0,05). Les jeunes poussins des deux esp\èces de tourterelles \étaient indemnes des attaques des ectoparasites.
