Abstract
Thepresent work was carried out to make a pilot study of mantis population usingmark release recapture technique in El-Fayoum governorate through the year of2008 to estimate the population density and the biodiversity of some mantis fauna.This study form a nucleus of more extensive studies on mantis ecology which isstill not clear and shed the light on the nature of mantis population and someproblems facing this beautiful insect in Egypt.
Highlights
Mantodea is a small insect order represented by 2452 species on 446 genera and 14 families around the world (Otte& Spearman, 2005)
As any other biological control agent, the population density of praying mantis playing the key role on its impact on pest populations so with the increase of number of mantis on fields and gardens we can achieved acceptable level of control, tacking on consideration the bad effect of this increase on other beneficial insects including other mantis (Carroll & Salt, 2004; Jervis, 2005)
The first investigation was made during March; four species of mantis were collected (Sphodromantis viridis Forskål – Miomantis paykullii Stål - Empusa sp.Oxyothespis dumonti Chopard) all of them in nymph stage, on the first two visits11 individuals were marked for three species (Empusa sp.-Miomantis paykullii Stål,Oxyothespis dumonti Chopard) as only one individual of Sphodromantis viridis Forskål was recorded from the area during these visits
Summary
Mantodea is a small insect order represented by 2452 species on 446 genera and 14 families around the world (Otte& Spearman, 2005). Mantodea of Egypt form one of unique and sophisticated mantis fauna on the planet, with 59 species on 21 genera and 4 families (Nasser 2010). All mantis are predators feeding mainly on other insects and arthropods (Preston, 1990; Ehrman, 1992). Mantis are diurnal insects live mainly on tropical and sub-tropical regions with only few species occur on cold area (Ehrman, 2001a). They live solitary on trees, shrubs and grasses, to make their camouflage mission to get their prays and avoiding enemies. As any other biological control agent, the population density of praying mantis playing the key role on its impact on pest populations so with the increase of number of mantis on fields and gardens we can achieved acceptable level of control, tacking on consideration the bad effect of this increase on other beneficial insects including other mantis (Carroll & Salt, 2004; Jervis, 2005)
