Entomofauna investigations in the apricot orchards, Prunus armeniaca L. (Rosales Rosaceae), in Ouled Si Slimane, Batna, North East of Algeria

Abstract

Researches carried out in the past years allowed to list an entomofauna that lives on the apricot orchards, Prunus armeniaca L. (Rosales Rosaceae), in Ouled Si Slimane (Batna Department, Algeria). The investigated period was from October 2014 until May 2015. The sampling techniques used were: hunting in sight, barber pots, colorful traps, entomological umbrella and the filleting net. We have identified a total of 125 species divided into 9 orders and 54 families in which Coleoptera and Hymenoptera were quantitatively represented. The phytophagous were the most present. Its Shannon Value exceeds 4.5 Bits and indicates a Specific Richness of the insects and diversification of ecological niches in this kind of fauna.

Invertebrate’s diversity on persimmon crop (Diospyros kaki Thunb.) at low altitude in Mechtras region, North Algeria

“…In our study about invertebrates fauna associated to persimmon trees, we have caught 115 species, distributed in 57 families belonging to 13 orders and 6 classes. Chafaa et al (2019) confirmed in their study on apricot orchards, 125 species belonging to 54 families and 9 orders, in Batna region of North-East Algeria. Vasquez The total wealth of invertebrate reported were 63 species for colored traps and 66 species for Barber pots.…”

Diversity of arthropods subservient to olive groves in arid region (Northeastern Algeria)

“…The Shannon diversity index, Evenness and Simpson reciprocal index offer a comprehensive overview of the diversity across all populations. These indices take into account the number of individuals from various populations, including different stand and trophic groups, in addition to the number of species (Chafaa et al, 2019b).Importantly, these diversity indices provide more information than simply counting the numbers of species present (Drouai et al, 2018).…”

“…According to Haddad et al, (2009), the low plant diversity can lead to a decrease in arthropod diversity and a shift in trophic structure. Phytophagous insects exhibit a high degree of selectivity for plant species that they prefer (Chafaa et al, 2019b). The phytophagous species represented by pollinators from bees (Apis mellifera; Bombus terrestris; Halictus scabiosae) and ants (three species of Tapinoma), are related to the flowering period of olive trees and the presence of weeds in and around field (Deghiche-Diab et al, 2021).…”
