Abstract:To contribute to the knowledge of beetles (Coleoptera) of the mountainous region of Morocco, Talassemtane National Park (Western Rif, Chefchaouen district, Morocco) was surveyed. This is an exceptional protected area of the Mediterranean Intercontinental Biosphere Reserve (RIBM). The inventory was made using different traps combined with active searching periodically during 2013 and 2014. Among numerous species belonging to various families, the darkling beetles (Tenebrionidae) represent one of the major groups, in terms of diversity and heritage value. Thirty five species were identified, two species are new records to Morocco, and two other species, which were hitherto only known by the type specimens, have been rediscovered
En esta segunda parte, presentamos la subfamilia Pteromalinae en Marruecos, que incluye 86 especies pertenecientes a 50 géneros. Quince géneros y 37 especies se enumeran por primera vez en la fauna marroquí, de las cuales 9 han sido recientemente identificadas, 24 se han encontrado en la bibliografía y 4 están depositadas en museos de historia natural. Se proporciona una lista actualizada de especies marroquíes, incluida su distribución por regiones, su distribución general y sus huéspedes.
The stem borer, Lixus algirus L. (Coleoptera: Curculionidae) is the major insect pest of faba bean in the Mediterranean region. This study investigates the field biology and fluctuation of L. algirus at Douyet research Station in Morocco during two cropping seasons 2014-2015 and 2015-2016 using two local faba bean varieties. The influence of sowing dates and varieties on the damage caused by L. algirus was investigated over different locations and seasons using a split-plot design. The overwintering adults appear in the field from February by feeding over the leaves of faba bean plants. Eggs are laid from Mid-February through late April and mostly during March. The egg peak ranged from 0.75 to 1.1 eggs per plant. The number of larvae increases during March and peaked in April. The larval peaks ranged between 0.45 to 1.5 larvae per plant. The larval development takes an average of 42 days. Pupation lasts about 21 days within stems. Adults emerged in early June. Life cycle duration was 80 days. One generation of L. algirus was recorded on faba bean varieties in Morocco. The mean number of eggs showed a positive correlation with total rainfall. The number of pupae and relative humidity was negatively correlated. Peach and almond leaves were the most preferred by the newely emerged L. algirus adult during the summer and early autumn period. Planting dates did not affect L. algirus infestation levels over all varieties tested and locations.
The two Trichogramma species T. bourarachae and T. buesi belonging to two closely related groups, perkinsi and pintoi, were compared. The inter‐species crossings did not result in hybrids and, therefore, the two species show complete genetic isolation. Eleven morphometric characteristics (eight from male genitalia and three from male antennae) and seven ratios between the latter characters confirmed the validity of these species. Significant differences (P < 0.01) actually exist for 56% of the measured characters and the calculated ratios. Among the morphometric characters analysed, five contribute to the definition of the perkinsi and pintoi groups and allow for comparisons to be made. However, only two of them (40%) show a difference between the groups (P< 0.01). Such a result, in accordance with those from other studies, has led to the combination of the two groups synonymously, under the name of perkinsi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
