We examined morphological variations in Carabus granulatus L., 1758 (Coleoptera,
Carabidae) populations across different habitats in the Kaluga Region. Discriminant analysis
revealed subtle but significant morphological differences between populations, with pronotum
length being the key discriminating trait. Morphological variability was primarily driven by
historical microevolutionary processes rather than direct phenotypic adaptation to specific
habitats. Local ecological factors, such as microclimate and resource availability, had a
greater influence on morphometric traits than the general habitat type. Populations in the
eastern part of the Kaluga Region exhibited smaller body sizes due to intensive forest use.
A survey and identification were made of edible mushrooms from Salah Al Din Province,
central of Iraq, were conducted. The species were identified according to macroscopic
characteristics, such as the size, shape, color, and surface texture of the cap; the color of the
gills and their attachment to the stipe, if any, the number of pores per millimeter; and the color,
size , and surface texture of the stipe. Other features noted included the presence or absence
of the annulus and volva; Microscopic characteristics were also examined, including the size
of the basidium and the number of its spores; the color, size, and shape of the spores; the size,
shape, and type of cystidia, and whether cystidia were present or abse

Bathyplectes curcurlionis (Thomson) is the sole parasitoid encountered in west Baghdad parasitising larvae of alfalfa weevil Hypera postica (GylIenhal). Percent of parasitisation did not exceed 8% in 1989 and 1990 and overall rate of parasitisation was 5%. Additional reduction in percent of parasitisation caused by presence of the fungal pathogen Erynia phytonomi. High survival percent of weevil's larvae under the study conditions explains why this insect is a key pest of alfalfa. Suggestions were made to inhance the role of B. curcurtionis in controlling the weevil.

Calcareous nannofossils were documented from the upper part of the Cretaceous Balambo Formation in northern Iraq with the aim of determining an evidence for the Oceanic Anoxic Event. A detailed investigation of the calcareous nannofossils led to the identification of twenty-four species. Regarding these data, Discolithus litterarius (Górka, 1957) was identified at the studied interval with the age of Early Aptian.
Early Aptian assemblages are dominated by nannoconids that drop sharply within the D. litterarius nannofossil zone, which may be related to the nannoconid crisis recorded in the Early Aptian in the other parts of the world. This event is coincided by a decrease in CaCO3<

Some methods recommended abroad to control the oriental hornet, Vespa orientalis L., attacking the honey bee, Apis mellifera L., colonies were tested, with some modifications, for the first time under the Iraqi conditions. One of these methods was carried out by covering the hive entrance with a piece of queen excluder to prevent the hornet from entering the hive. Also, the position of hive stand was reversed to deprive the hornet from using the flight board as a stage for waiting and creeping toward the defending bees. The second method was carried out by fixing a cardboard cone as a bee passage at the hive entrance to hinder the entry of the hornet into the hive. Both of these methods were found to be unsuccessful to
