    Coexistence of Henosepilachna elaterii (Rossi, 1794) (Coleoptera Coccinellidae) on Citrullus colocynthis Schrad.(Cucurbitaceae) around the water dam of El Outaya (Biskra, Algeria)

    ABSTRACT
    Morphological studies (Total length from apical margin of clypeus to apex of elytra, width, body area and wing length) were carried out on the fourth larval instar, pupa and adult (male and female) of Henosepilachna elaterii (Rossi, 1794) (Coleoptera Coccinellidae) sampled from a Cucurbitaceae plant (Citrullus colocynthis Schrad.), which grow around the dam “Fountains of Gazelles” in Biskra (Algeria). The fourth instar larva and pupa measured 8.55 ± 0.20 mm and 2.56 ± 0.26 mm; 7.38 ± 0.36 mm and 4.81 ± 0.36 mm; length and width respectively. Adult beetles feeding on fresh leaves were hemi-spherical in shape and red ferruginous in color with 12 black spots on the elytra. Females measured 6.97 ± 0.25 mm in length and 5.37 ± 0.34 mm in width, while males were 6.17 ± 0.31 mm in length and 4.80 ± 0.37 mm in width. Duncan’s multiple range tests allowed us to classify specimens in increasing order of area as follows: 4th instar larvae 20.29 ± 0.15 mm2, adult male 26.41 ± 2.52 mm2, pupa 28.14±0.31 mm2 and adult female 31.73 ± 1.84 mm2. Moreover, the female wing was longer with a value of 10.07 ± 0.54 mm compared to the male, which recorded 8.72 ± 0.60 mm in length. Both adults and larva were serious pests of Citrullus colocynthis which resulted in skeletonisation of leaves.

    Inventory and geographical distribution of Acacia Mill. (Fabaceae Mimosaceae) species in Algeria

    ABSTRACT
    The geographical distribution of the genus Acacia Mill. (Fabales Mimosaceae) in Algeria was determined after the prospect, localization and description of the various species populations overall Algerian territory. Twenty-four regions were prospected, based on relative species abundance. Among the ten-species found in Algeria, only A. karroo and A. saligna can be found in the whole country. However, there are some concentrations in certain northern regions. Acacia decurrens was only found in the Northeast, with high concentrations at the National Park of El Kala. Five of them are recorded in the southwest (A. albida, A. ehrenbergiana, A. nilotica, A. seyal and A. tortilis). Acacia farnesiana is indicated in the Northeast and the Northwest. Acacia laeta individuals were very rare. According to the climatic data during the years 2000-2016, the following species adapted to the annual pluviometry, that is lower than 100 mm: A. albida, A. ehrenbergiana, A. laeta, A. nilotica, A. seyal and A. tortilis. Three species (A. karroo, A. farnesiana and A. saligna) are in zones with an annual pluviometry between 250 and 500 mm). Acacia decurrens is located in a zone in which the annual precipitation exceeds 1000 mm. This study shows the distribution of the Acacia species in Algeria.

    Coexistence of Danaus chrysippus (Linnaeus, 1758) (Lepidoptera Nymphalidae) on the Milkweed Pergularia tomentosa L. (Asclepiadaceae) in Aïn Naga (Biskra, Algeria)
    https://doi.org/10.31396/Biodiv.Jour.2019.10.4.315.320

    ABSTRACT
    A butterfly species, Danaus chrysippus (Linnaeus, 1758) (Lepidoptera Nymphalidae), also known as African Queen, is recorded for the first time in the arid region of Aïn Naga (Biskra, Algeria). Adults of D. chrysippus were recorded in a survey from October 2018 to February 2019 on their host plant Pergularia tomentosa (Milkweed) (Asclepiadaceae). Additional data on the life cycle and behavior of this species are given.
