Small pigeon louse, Campanulotes bidentatus compar were studied in vitro. They were subjected to different temperature i.e. 20 ̊C, 25 ̊C, 30 ̊C, 35 ̊C, 40 ̊C and 45 ̊C and relative humidity i.e. 33%, 50%, 75% and 90% to determine lice longevity, an incubation period of egg, daily egg production and hatching of an egg. The optimum temperature range between 30-40 ̊C was found essential for normal
survival of C. bidentatus compar. The best suitable temperature and humidity were found to be 75±1 ̊C and 75±1%. Temperature above 40 ̊C was lethal to adult as well as developing stages of C. bidentatus compar. Egg laying, survival time, incubation and hatching period dropped as temperature and relative humidity increased or decreased mention range (i.e. above 40  ̊C and 75% and below 30  ̊C and 50%)

The chewing louse Stenocrotaphus gigas, known locally as »chicken bug louse« or »large chicken louse«, originally infested only the Guineafowl Numida meleagris. However, at least 130 years ago this insect, a member of the African fauna, established itself world-wide on the domestic hen Gallus gallus f. dom. The first description of the nit of Stenocrotaphus gigas, from hens in central Germany, was made by Wilhelm hohoRsT in 1939. According to this description, the domed egg cap (operculum) has a very long thread-like attachment (calyptra), which at its base is broadly ribbed (lamellae-like). This delicate top attachment can very easily break off, and perhaps because of this, or because of chemical treatments, this calyptra has yet to be found on S. gigas eggs from hens in Uttrakhand, India.


The eggs of Chicken bug louse, Stenocrotaphus gigas is somewhat cylindrical or pot like in appearance, measuring 1.34- 1.40 mm in length (after hohoRsT up to 1.25 mm) and 0.52- 0.56 mm in width. It bears faint hexagonal marking on the whole egg shell and obliquely fitted operculum (0.32-0.36 mm in width) on egg mouth. The anterior half of operculum is like visor of a cap and bear 50-60 micropyles.


The results confirm the opinion that egg morphology could be used for preparation of taxonomic key for identification of both phthirapteran species and genera. The further development of the young discipline of Phthirapteran oology is pleaded for.

 

German title: Über das Ei des »Hühnerfederlings« Stenocrotaphus gigas (Taschenberg) (Phthiraptera: Ischnocera, Goniodidae)

Zusammenfassung

Der als »chicken bug louse« oder »large chicken louse« bezeichnete Federling Stenocrotaphus gigas (TaschenbeRg, 1879) bewohnte ursprünglich nur das Perlhuhn Numida meleagris. Seit mehr als 130 Jahren hat sich dieses afrikanische Faunenelement weltweit auch auf dem Haushuhn Gallus gallus f. dom. etabliert. Die erste Beschreibung der Niß von Stenocrotaphus gigas, und zwar aus mitteldeutschen Haushühnern, gab Wilhelm hohoRsT 1939. Danach trägt der gewölbte Eideckel einen sehr langen fadenförmigen Aufsatz, der an der Basis breit lamellenartig ist. Dieser zart gebaute Aufsatz bricht sehr leicht ab. Vielleicht deshalb und besonders infolge chemischer Behandlung konnte er an gigas-Eiern von Haushühnern aus Uttrakhand in Indien nicht festgestellt werden.


Die dort untersuchten Eier haben eine annähernd zylindrische und etwas bauchige Form. Die weißlichen Eier messen in der Länge 1,34-1,40 mm (nach hohoRsT nur bis zu 1,25 mm), in der Breite 0,52-0,56 mm. Die gesamte Eioberfläche besitzt eine feine hexagonale Felderung. Der Eideckel ist schräg aufgesetzt und 0,32-0,36 mm breit. Die vordere Hälfte des Eideckels ist marginal mit einer reißverschlußartigen halbkreisförmigen Aufreihung von 50 bis 60 Mikropylen versehen.


Die Befunde bekräftigen die Auffassung, daß für die Diagnostik von Arten und Gattungen der Phthiraptera die Berücksichtigung ihrer Eimorphologie nützlich ist. Es wird für eine Weiterentwicklung der noch jungen Disziplin der Oologie der Tierläuse plädiert.

Chicken louse, Gallacanthus cornutus (Schömmer, 1913) (Menoponidae s. l.) have piercing and sucking-type mouthparts. They are haematophagous, chitinophagous and running rapidly on host’s body which cause irritation, itching and discomfort to the infested bird. The egg of G. cornutus is highly specific measuring 0.70-0.80 mm in length and 0.27-0.32 mm in width. The operculum exhibited bee hive-like polygonal markings and bears 12-14 micropyles which are arranged at the circumference of operculum. One fifth of anterior egg chorion has bearing bristles arranged in 8-9 rows with characteristic markings. The egg of G. cornutus found to be quite specific and highly variable to intrageneric species. So, egg morphology could be used for development of new branch of science (phthirapteran oology), identification of species providing clue about present as well as past infestation on host and included as intrageneric characteristics in insects.

German title: Die Mikromorphologie des Eies vom Hühnerläusling Gallacanthus cornutus (SCHÖMMER) (Insecta: Phthiraptera: Amblycera, Menoponidae s. l.)

Zusammenfassung: 

Die beim Haushuhn Gallus gallus forma domestica häufig anzutreffende Amblyzere Gallacanthus cornutus (Schöm- mer, 1913) ernährt sich von Blut und Federteilchen ihres Wirtes. Auch durch ihre flinke Bewegung auf der Haut- oberfläche kann sie bei größerer Befallsintensität negativen Einfluss auf das Wohlbefinden des Wirtes nehmen. Das Ei (Niß) von Gallacanthus cornutus misst in der Länge 0,70-0,80, in der Breite 0,27 -0,32 mm. Hier vorgestellte rasterelektonenmikroskopische Aufnahmen zeigen, dass nur der zitzenförmige Eideckel polygonal gefeldert ist und in kreisförmiger Anordnung jeweils 12-14 Mikropylen besitzt. Auf der Spitze des Eideckels ist kein fadenförmiger Fortsatz nachweisbar. Unterhalb des Operculatum ist das Exochorion auf etwa einem Fünftel der Eilänge mit 8-9 Reihen von gekräuselten Fortsätzen (»Kräuselhaar«) besetzt. Darunter ist die Eioberfläche glatt. Die Morphologie des Eies von Gallacanthus cornutus ist vermutlich zumindest gattungsspezifisch, doch ist bisher noch keine andere Gallacanthus-Art beschrieben worden. Die Eimorphologie bei Tierläusen (Phthiraptera) interspezifisch genauer unter die Lupe zu nehmen, verspricht einen interessanten, nicht ganz neuen, aber bisher kaum über Ansätze hin- ausreichenden Zweig in der Phthirapterologie: die Oologie.

Lice infest wide range of livestock and incur loss of million dollars to poultry, leather and dairy industries. The parasites have also reservoir and spread pathogenic strain among host which indirectly increase the mortality and decline vitality host. The impact of chewing lice on live host confined equivocal and contradictory as cited in literature by previous phthirapterist. In the present work, impact of Gallacanthus cornutus (Schömmer 1913) (Menoponidae s. l.) on meat production (weight gain) of domestic fowl has been accessed at Purola (Uttarkashi), India. The 100 birds of similar age and breed were kept in two separate pens (infested and uninfested flocks). The weight gain of two groups has been recorded and statistically analysed. The weight gains in uninfested categories were much quicker than infested categories. G. cornutus able to reduce as much as 900 gm body weight per bird. The young chickens (2 to 4 months) were found to be severely affected as compared to adult. Two tailed paired t-test was found significant between weight gain in uninfested and infested birds (t (4) = 4.702, p = 0.005). So, it causes great loss to the poultry industry as well as the economy of any country.

German Title: Der Einfluss des Hühnerläuslings Gallacanthus cornutus (Insecta, Phthiraptera, Amblycera, Menoponidae s. l.) auf die Fleischproduktion beim Haushuhn Gallus gallus forma domestica

Zusammenfassung: Auf praktisch allen Arten der vom Menschen gehaltenen Nutztieren leben natürlicherweise Tierläuse (Phthiraptera). Unter den Bedingungen der konzentrierten Tierproduktion bewirken sie in Geflügel-, Leder- und Milchwirt- schaft Schäden in Millionenhöhe. Der Einfluss von Haarlingen und Federlingen auf ihre als Haus- und Nutztiere gehaltenen Wirte wird in der Fachliteratur von Spezialisten unterschiedlich bis widersprüchlich bewertet. In der vorliegenden Arbeit ist der Einfluss von Gallacanthus cornutus (Schömmer 1913) (Menoponidae s. l.) auf die Fleischproduktion über die Veränderung der Körpermasse bei Haushühnern in Purola (Bezirk Uttarkashi) in Indi- en untersucht worden. 100 gleichaltrige Hühner einer Herkunft wurden im Alter von zwei Monaten chemisch von Ektoparasitenbefall befreit. Jeweils 50 wurden in zwei separaten Verschlägen gehalten. Die eine Gruppe wurde mit jeweils 20 Individuen von Gallacanthus cornutus pro Wirtsindividuum infiziert, die andere blieb davon verschont. Die Massezunahme der Hühner vom Küken- bis zum Erwachsenenstadium verlief von Juli bis Dezember in beiden Gruppen unterschiedlich. Sie war bei den nicht mit G. cornutus infizierten Hühnern größer als bei den infizierten. Der Zweistichproben-t-Test für abhängige Stichproben ergab einen signifikanten Unterschied (t (4) = 4,702, p = 0,005). Daraus ist der Schluss zu ziehen, dass Gallacanthus cornutus-Befall bei industriemäßig gehaltenen Haus- hühnern einen klar negativen Einfluss auf ihre Massezunahme ausübt und damit zu ökonomischen Verlusten führt.

67.6% of the fowls examined in 18 different localities of Garhwal, during 1992-94 were found infested with the poultry shaft louse, Menopon gallinae. Some factors like host sex, feather condition and mode of captivity had marginal effect on the prevalence of louse. Incidence rates remained distinctly higher on older birds as compared to younger ones. Mean monthly incidence did not fluctuate appreciably during different months of the year. However, intensity of infestation remained distinctly higher during the summer months.

SEM studies have been performed to record the microtopology of eggs of poultry shaft louse, Menopon gallinae. The egg mouth is boardered by two rows of apophyses. The apophyses belonging to the inner row have been found quite porous and spongy. The polar thread is made up of several fine strands. The eggs stigma remains indistinct.

Nymphs of successive generations of Menopon gallinaeI (L. 1758), parasite on Gallus gallus f. domestica, highly resemble to each other from the moment of emergence and show the number of abdominal segments characteristic of adult form. Apart from evident differences in body size, the relative size of abdomen (head, thorax and abdomen ratio), rising chitinization of the cuticle, the succesive nymph stages can also be distinguished on the basis of progression of chaetotaxy. Furthermore, brush (spiniform setae) on fourth sterna and spiracular aperture become evident in third instar nymphs.

The population structure of Bovicola caprae on goats has been recorded by examining 57 goat skins (45 by brushing cum searching and 12 by disolving method). Population, sex ratio, adult nymph ratio has been recorded at different levels of infestation. The female dominated over the male population and M:F ratio has been found to be 1:2 by brushing cum searching and 1-1.7 by disolving method. Likewise, A:N was found to be 1:1.2 by brushing cum searching and 1-1.7 by disolving method. The number of males and females follow similar pattern throughout population and were found to exhibit a high degree of correlation.

The prevalence of two phthiraptera species, Bovicola caprae and Linognathus africanus on 1048 goats from Dehradun (India) was 79.2% and 38% respectively. Prevalence of both species was higher on visibly weaker and less hairy goats. Sex related differences in prevalence were not found. The prevalence of L. africanus was slightly higher on young goats but the same was not true in case of B. caprae. The incidence of B. caprae showed moderately negative correlation with environmental temperature and photoperiod. The relative intensity of B. caprae has been found higher during winter months, followed by summers. Study primarily deals with lice but the information about prevalence of other ectroparasites like ticks, fleas and keds, has also been supplemented.
