PREDATORY INSECTS ASSOCIATED WITH MOSQUITOES AND THEIR RELATIVE ABUNDANCE AT DAKAHLIA GOVERNORATE.
Ten species of predatory insects were found associated with mosquitoes larvae and pupae in three districts (Mansoura, Talkha, and Miniet El-Nasr) from January 2005 till December 2007 at Dakahlia governorate in the present study. These predatory insects are belonging to three different orders (Heteroptera, Coleoptera, and Odonata) as the following: Order Heteroptera: Micronecta plicata (Costa) (Corixidae), Diplonychus urinator (Durfour) (Belostomatidae), Lethocerus niloticus (Stal) (Belostomatidae), and Anisops sp. (Notonectidae), Order Coleoptera:Rhantus elevatus Sharp (Dytiscidae), and Sternolophus soleiri Laporte de Castelnau (Hydrophilidae), and Order Odonata:Anax imperator Leach (Aeshnidae), Trithemis annulata Pale (Aeshnidae). Pantala flavescens Fabricius (Aeshnidae), and Ishnura senegalensis Rambur (Agrionidae).
During season of 2005, the more abundant species was Anisops sp < em>. In addition, it listed the highest percentage in Talkha district (48.43%). But R. elevatus was the next highest predator and it approximately similar in the three districts. Moreover, M. plicata was the next one in Meniet El-Nasr district (12.91%). Meanwhile, L. niloticus represented the lowest percentage to the total predatory insects in Mansoura and Talkha districts but in Meniet El-Nasr district, D. urinator was the lowest percentage.
In season 2006, Anisops sp. was the most abundant predator species (53.80%, 46.90 and 47.65% in Mansoura, Talkha, and Meniet El-Nasr, respectively). The second one was R. elevatus ( 19.88, 16.29 and 21.04% in the three districts, respectively). In addition , L. niloticus represented the lowest percentage of the total predatory insects in Mansoura and Talkha districts. Whereas in Meniet El-Nasr district, D. urinator was the lowest percentage.
During season of 2007, Anisops sp. was the most numerous species (44.02, 47.36, and 49.73%) followed by R. elevatus (19.55, 18.39, and 17.86%), M. plicata (14.35, 12.89, and 10.99% ),and S. soleiri (5.77, 5.24, and 5.77%) in Mansoura, Talkha and Meniet El-Nasr districts, respectively. Whereas in Mansoura and Talkha districts, L. niloticus was the lowest predator species.
