The last instar larva and the pupa of Psammoecus scitus Yoshida & Hirowatari, all instar larvae of P. simoni Grouvelle, and the last instar larva of P. hiranoi Yoshida & Hirowatari are described, and their morphologies are compared among species and instars. Larval association for P. simoni was confirmed by DNA barcoding. Apart from a brief description of the pupa of Cryptamorpha brevicornis (W...

A total of 220 soil and root samples containing mixed populations of 26 genera and 38 species of phyto...

The chemical composition of the essential oils (EOs) of four Lamiaceae (Thymus capitatus Hoff. et Link., Rosmarinus officinalis L., Origanum vulgare L. and Mentha pulegium L.) growing wild in Tunisia was analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Obtained results showed significant variations among the different species. The major constituents identifi...

Bucrates weissmani n.sp. is known from four localities in southern arizona. It is smaller and more slender than the other four species of Bucrates, making it superficially similar to the Central american copiphorine Caulopsis cuspidata, but more fundamental features refute the notion that it belongs in Caulopsis rather than Bucrates. Four other species of Bucrates are known. Two of these, capit...
