Abstract | The chewing lice (Phthiraptera: Insecta) are parasitic insects of variety of birds belonging to the large family of Phasianidae (Aves: Galliformes). The lice have strong mandibles with biting mouth parts and develop specific host-parasite relationship. They cause acute to chronic infestation to hosts directly. These parasitic insects are the source of various diseases, like flue, and also serve as a vector of some bacteria and helminthes parasites. Presently only one type of host, guinea fowl Numida meleagris (Linnaeus, 1758) was selected and examined for parasites examination, investigation, identification, population density, means and rate of infestation of from different urban and rural localities of Sindh, Pakistan. There were 15 guinea fowl Numida meleagris (Linnaeus, 1758) were captured and brought to the Parasitological laboratory of Department of Zoology, University of Sindh, Jamshoro. The study was carried out from April 2015 –March 2016. Guinea fowls Numida meleagris (Linnaeus, 1758) were sprayed with Permathrin (Coopex powder) and ket on white paper sheets for about 32-35 minutes. The fowls were checked time to time after 2 to 3 weeks. The chewing lice were collected hand picking methods with fine brushes and preserved in 70-75% ethyl alcohol. The permanent microscopic slides with cover slips were prepared for final mounting in Canada balsam. At present 130 specimens were recovered and classified into 4 species which belongs to 3 genera. The species and their prevalence are 19.23% for Menopon gallinae (Linnaeus, 1758), 23.84% for Menacanthus stramineus (Nitzsh, 1818), and 22. 30% for Menacanthus abdominalis (Piaget, 1880) which belongs to the family Menoponidae and 34.61% for Goniocotes gallinae (de Geer, 1776) which belongs to the family Philopteridae. All four species were reported first time as new host and new locality records from the study area. All species of chewing were described and compared with other related species and developed taxonomic key.

1. Introduction

The family Phasianidae (Phthiraptera: Insecta) is one of the largest family of galliform birds (Aves: Galliformes). The birds are terrestrial, small to large size and often called gallinaceous birds. One of the bird guinea fowl Numida meleagris (Linnaeus, 1758) is small size resident domestic fowl of province of Sindh, Pakistan. It is poultry bird and man usually kept them in their houses for production of eggs. The guinea fowl Numida meleagris (Linnaeus, 1758) is easily parasitized by parasitic insects chewing lice and causes infestation and become a source of infection to man. The fowl commonly feeds on small arthropods and control ticks, flies, locusts and scorpions population. The chewing lice (Insecta: Phithraptera) are biting and obligatory parasites of many birds and mammals. They have no free-living stage in their life cycle. No intermediate host is required and for the completion of life cycle. The chewing lice have exaggerated head with large mandibles. There are more than 450 species of chewing lice parasitizing gallinaceous birds (Price et al., 2003). The chewing lice develop mutual symbiotic association with their host. If we separate them the death rate of lice was observed (Nelson and Murry, 1971). The entire life of chewing lice is committed to parasitism. They require the host body for food, shelter, protection, multiplication and for reproduction (Clayton, 1991). The study on identification and classification of Mallophaga (Phthiraptera: Insecta) is still continue (Lyal, 1985; Johnson and Whiting, 2002). The chewing lice principally are classified into four Suborders: Anoplura, Ryncophthirina, Amblycera and Ischnocera (Cruickshank et al., 2001). The two suborders amblycera and ichnocera parasitizing birds only. The structural characteristics of amblycera follows, slow to fast moving on the head and neck region on fowls, have rounded bodies and large heads with large mandible (Askew, 1971). Mouth parts are opposable which move in perpendicular plane and articulated to the ventral surface of head (Clay, 1949; Nelson, 1972). The neck has two visible segments mesothorex and metathorex. The structural characteristics of ischnocera follows, are susceptible to preening, flattened, elongated and remain attached to the body of the hosts all time (Smith, 2001). The head is prominent, mouthparts move in parallel plane (Kellogg, 1896; Snodgrass, 1905; Cummings, 1913; 1916). The two visible segments of thorax are combined together to form only one segment called pterothorex. There are usually 11 segments of abdomen. The complete shape of the body is maintained by abdominal segments. The chewing lice are significant economically as they serve as most important pest and infest the domestic fowls and poultry industry. The most frequent infested birds include domestic fowls, chickens, Turkeys fowls, pigeons, sparrows, doves, ducks, etc. and also other animals include dogs, cats, cattle, horses, etc. (Kettle and Pearce, 1974; De Vaney, 1976; Nelson et al., 1977; Arends, 1997). The suborder amblycera are classified into seven families: Menoponidae, Laemobotheriidae, Ricinidae, Abrocomophagidae, Boopiidae, Gyropidae, and Trimenoponidae, in which first three parasitizing birds and causes infestation. The suborder ischnocera are classified into three families: Philopteridae, Heptapsogasteridae and Trichophilopteridae first two parasitizing birds, except one, Trichophilopteridae, only parasitize Primates (Mammalia). The gallinaceous birds are the major part of poultry industry, include domestic fowls, chickens, partridges and quails (Batairs), pea fowls and guinea fowls are second source protein and meat production in the world. The research was based on investigation, collection, observation, identification, prevalence, population density and rate of infestation of lice on host body Guinea fowl Numida meleagris (Linnaeus, 1758) in the Sindh, region Pakistan. This was first attempt of such morphological and ecological studies of chewing lice in Sindh, Pakistan. The recognition of valuable information will finally help in preventing and managing the transmission of variety of diseases and their causative agents. The identification and completion of their life cycle contribute the knowledge of chewing lice fauna in the region (Ansari, 1944; Brown, 1974; Abebe et al., 1997; Ilves et al., 2013; Audi and Asmau, 2014). The distribution and identification of chewing lice of Indo-Pak regions were followed by (Lakshminarayana, 1979; Naz et al., 2010).

2. Materials and Methods

A total of 15 guinea fowl Numida meleagris (Linnaeus, 1758) were captured and observed for chewing lice population. The study was conducted from April 2015 to March 2016 from different urban and rural regions of Sindh, includes Hyderabad, Karachi, Larkana, Badin, Thatta and Mirpur khas located in Province Sindh, Pakistan. The guinea fowl Numida meleagris (Linnaeus, 1758) were investegated from their natural environment and brought to the Parasitology laboratory of Department of Zoology, University of Sindh, Jamshoro. Each fowl was sprinkled with Permathrin (Coopex powder) and kept on white paper sheet for about 32-35 minutes. The fowls were examined carefully with fine brushes dipped with 70% to 75% alcohol. The method is called hand picking method. Every specimen was preserved in small vials containing 70-75% ethyl alcohol. The infested fowls checked time to time 2 to 3 weeks. The permanent microscopic slides were prepared by following standard methods. First step was maceration in KOH for overnight, second step was neutralization in dilute acetic acid for few minutes, third step was cleaning with pressing, fourth step was dehydration of lice from 10% 10 100% ethyl alcohol, fifth step was cleaning of lice with clove oil, six step was fixing with xylol and finally mounting in Canada balsam. The drawings were made by microscope of drawing tube attachment. All measurements were taken by using ocular micrometer and measurements were taken in millimeters and identified by the following abbreviations, like TL total body length, HL head length, POW preocular width, TW temporal width, PL prothorex length, PW prothorax width ML metathorax length MW metathorax length AL abdominal length GL genitalia length and GW genitalia width. Measurements include prevalence and mean deviation and ranges (Palma, 1978; Price et al., 2003).

3. Results and Discussion

A total of 15 guinea fowls were captured and investigated for chewing lice population. About 130 specimens were collected, examined and identified from guinea fowl Numida meleagris (Linnaeus, 1758). The collected specimens were classified into 4 species which belongs to 3 genera. It includes genera Menacanthus and Menopon of the family Menoponidae and the genus Goniocotes of the family Philopteridae. Out of 4 species of chewing lice only two species first time were reported from the guinea fowl Numida meleagris (Linnaeus, 1758) not only from the Sindh region but also in the World (Price et al., 2003). The two species includes Menacanthus abdominalis (Piaget, 1880), and Goniocotes gallinae (de Geer, 1776) The research work was conducted in different urban and rural localities of Sindh, includes Hyderabad, Karachi, Larkana, Badin, Thatta and Mirpur Khas from Sindh, Pakistan. The calculation and prevalence of 04 species of lice was made in (Table 1 and Figure 1) on guinea fowl Numida meleagris (Linnaeus, 1758) and then their main taxonomic characters were described along with their measuring body parts (Table 2) from the study area.

It was dark yellow medium sized chewing lice. It was fast moving has strong and heavy body and belong to the family Menoponidae (Figure 2). During present investigation 29 specimen of Menacanthus abdominalis (Piaget, 1880) were recovered. The prevalence was calculated 22.30% on the host bird. It was recorded first time as a new host and new locality record from guinea fowl Numida maleagris (Linnaeus, 1758) from Sindh, Pakistan. Body usually oval to round, the anterior margin of head was not convex; presence of 0.07mm long postpalpal process 0.07; presence complet scleroized gular plate; prosternal evidence of posterior plate having pointed process; presence of two anterior metanotum setae; presence of small postspiracular setae on tergites II-III and VII; genital characteristics were typical to the species; evidence of selender like anal fringe; evidence of large sized basal apodeme; presence of fine genital sclerite which were in pieces shaped.

An observation and examination of the data in the checklist of the world (Price et al., 2003) reveals that other number of chewing lice Colpocephalum tausi Ansari, 195; Cuclotogaster cinereus Nitzsch, 1866; Goniodes dissimilis Denny, 1842 and Lipeurus tropicalis Peters, 1931; habitually infesting poultry fowls. It was investigated through research that the presence of parasitic insects on body of the host prevails because of increased temperature and humidity of particular regions is the favorable medium for increasing their fecundity rates (Sayeed et al., 2005). It was also investigated that occurrence of chewing lice into two suborders of Mallophaga (Phthiratera: Insecta) were different. The suborder amblycera consisting of lice species were active and fast running and spend most of the time on the body surface of the fowls. In the suborder ischnocera consisting of lice species were less active and most of the time attached to feathers of fowls (Ash, 1960). It was concluded that 15 guinea fowls were examined and 13 were positive with total prevalence of 90.02% was occurred. Only 4 species were recovered as new host and new locality records from the study area. This was the first investigation on local guinea fowl Numida maleagris (Linnaeus, 1758) from the different urban and rural localities of Province Sindh, Pakistan.

Conclusions and Recommendations

Presently two species of chewing lice Menacanthus abdominalis (Piaget, 1880) of family Menoponidae and Goniocotes gallinae (de Geer, 1776) of family Philopteridae were reporting first time from guinea fowl Numida meleagris (Linnaeus, 1758) from the study area and making a new host and new locality records in the world (Price et al., 2003). Occurrence of chewing lice on host causes declining health and reduced production of eggs in hosts. Annoyance, frustration, impatience, aggravation, intolerance, and keenness were observed in fowls. Not sufficient work was carried out except Karachi from Sindh, Pakistan. The first work on lice was done before Indo-Pak, partition from Punjab (Faisalabad) from Pakistan. The study needs more research on different parameters to prevent host health like clinical pathology caused by fleas, mites and ticks on birds and to find out more results and we can prevent the poultry industry from great economic loss. Galliform birds (Phthiraptera: Insecta) carry large number of parasitic insects chewing lice which causes enormous pathogenicity in the host birds and decreased their health and food production
