Ebook "Ecology, systematics, and the natural history of predaceous diving beetles (Coleoptera: Dytiscidae)" will allow a greater appreciation of dytiscids as model organisms for investigations of fundamental principles derived from ecological and evolutionary theory. Contributed chapters are by authors who are actively engaged in studying dytiscids and each chapter offers a synthesis of the current knowledge of a variety of topics and will provide future directions for research.

The diversity and evolutionary success of beetles (Coleoptera) are proposed to be related to the diversity of plants on which they feed. Indeed, the largest beetle suborder, Polyphaga, mostly includes plant eaters among its approximately 315,000 species. In particular, plants defend themselves with a diversity of specialized toxic chemicals.

Mealworm beetle T. molitor (Coleoptera: Tenebrionidae) (Linnaeus, 1758) is one of the most important cosmopolitan primary storage pests, scavenging on a variety of post-harvest grains and affecting the quality and safety of food and feed. In addition to being an important factor in feed hygiene, the insect can also be an epidemiological factor of canthariasis.

A preliminary checklist of blister beetles from Pakistan and Kashmir is carried out, with the inclusion of 79 species. Stenoria osellai sp. nov. from northern Pakistan, Hycleus pakistanus sp. nov. from Baluchistan, and Meloe (Micromeloe) pintoi sp. nov. from Indian Kashmir are described. Three genera, namely Stenoria, Psalydolytta, and Rhampholyssa, and several species belonging to both subfamilies Nemognathinae and Meloinae, are recorded for the first time from these countries, whereas the genera Cerocoma and Glasunovia, previously cited, are excluded.

Cannibalism or intraspecific predation, where one species feeds on individuals of its own species, is a widespread phenomenon in most aphidophagous coccinellids. Laboratory studies were conducted on the cannibalistic behavior of various developmental stages of Coccinella septempunctata L. (Coleoptera: Coccinellidae) in the presence and absence of natural food, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae). In both the presence and absence of aphids, the eggs and 1st and 2nd instars of C.

The aim of this study was to investigate the biodiversity and structure of the Carabidae community living at the edges of a Ramsar wetland in northeastern Algeria, as well as to analyze the effect of environmental variables on this Carabidae community. The study site included two stations (T1, T2). From November 2016 to October 2017, the carabidofauna was sampled fortnightly using pitfall traps. The structure and diversity of the beetle community were measured using nonparametric indices, i.e. species richness, diversity indices, accumulation curves, and similarity analysis.

The main aim of this study is to contribute to the systematics relating to the family Buprestidae, by studying the male external genital organs (aedeagi) of six species belonging to the genera Acmaeodera, Acmaeoderella, Anthaxia, Capnodis, and Perotis, none of which had been illustrated previously. Samples of these species were collected from the province of Ankara, Turkey, and the aedeagus of each was described and illustrated in detail for the first time. The findings were then compared with the current literature.

The Ambrosia Fusarium Clade phytopathogenic Fusarium fungi species have a symbiotic relationship with ambrosia beetles in the genus Euwallacea (Coleoptera: Curculionidae). Related beetle species referred to as Euwallacea sp. near fornicatus have been spread in California, USA and are recognized as the causal agents of Fusarium dieback, a disease that causes mortality of many plant species.

Ladybird beetles (Coleoptera, Coccinellidae) are highly diverse in their feeding habits. Most of them are specialist feeders, while some can have a broad spectrum of prey. As a representative group of generalists, the tribe Coccinellini includes many aphidophagous species, but members of this tribe also feed on other hemipterous insects including coccids, psyllids and whiteflies.

The ladybird beetle Cryptolaemus montrouzieri Mulsant, 1853 (Coleoptera, Coccinellidae) is used worldwide as a biological control agent. It is a predator of various mealybug pests, but it also feeds on alternative prey and can be reared on artificial diets.

DNA barcoding is a useful tool in identifying species, biodiversity assessment, and revealing phylogenetic relationships of living organisms in the world. However, the DNA barcode data for leaf beetles in Vietnam is lacking. In this study, sixteen DNA sequences of 658 bp of COI gene from nine species (five genera; three subfamilies) of Chrysomelidae in Vietnam were (obtained). Intra- and inter-specific diversities, and phylogenetic relationships of these species were analyzed.

During surveying and collecting of predatory ladybird beetle species in Da Lat city, we recorded that Oenopia kirbyi commonly appeared on aphid-infected plants and weeds, but until now there have been almost no detailed studies on this species. With the hope of contributing to research on the use of predatory ladybird beetles in pest control, we studied the morphological and biological characteristics of Oenopia kirbyi in Da Lat city.

The main factors governing long-horned beetles distribution are the climatic and availability of suitable host plants. Past climate changes, result into evolution and spread of past floras, this made a profound influence on the distributional and evolutionary history of the survival representatives of Cerambycidae family in current days (Slipinski and Escalona, 2013).
