new locality data are given for eight species of geotrupidae and 65 species and sub-species of scarabaeidae dung beetles from iran. the species onthophagus (palaeonthophagus) anatolicus petrovitz, 1962, and onitis alexis ssp. septentrionalis balthasar, 1942, are recorded for the first time from iran.

Shared brood care or parenting chores are rare behaviors in insects. While a number of species exhibit biparental care, including wood roaches, passalid beetles, and some bark and dung beetles, only burying beetle males (Nicrophorus orbicollis) participate in all activities, remain with the brood throughout development, and can take over all parenting responsibilities if the female disappears. ...

Dung beetle community dynamics are determined by regional rainfall patterns. However, little is known about the temporal dynamics of these communities in tropical dry forests (TDFs). This study was designed to test the following predictions: 1) Peak diversity of dung beetle species occurs early in the wet season, with a decrease in diversity (α and β) and abundance throughout the season; 2) Nes...

Dung beetles are a group of insects that primarily use the dung (poop) mammals for feeding and nesting. These important breakdown recycling into soil, enabling nutrients in to cycle through ecosystem. provide many benefits health functioning both natural human-modified ecosystems, such as dispersing seeds, reducing livestock parasites, promoting plant growth. In this article, we will explore ba...

Abstract Dung beetles have been introduced to non-native sites perform dung removal function in cattle pastures. Despite some species becoming invasive, their behavioural and reproductive strategies remain be elucidated detail. Here we evaluated the shift behaviour reproduction of two beetles, Euoniticellus intermedius Digitonthophagus gazella , when they interact with same or other out native ...

Dimorphic sexual differences in shape and body size are called sexual dimorphism and sexual size dimorphism, respectively. The degrees of both dimorphisms are considered to increase with sexual selection, represented by male-male competition. However, the degrees of the two dimorphisms often differ within a species. In some dung beetles, typical sexual shape dimorphisms are seen in male horns a...

A bioassay was conducted to determine the impact of methoprene, an insect growth regulator (IGR), on fecundity, larval survival, and size of progeny for Onthophagus taurus Schreber. Adult O. taurus dung beetles were offered methoprene-treated manure in three to five replications each at concentrations of 0.08, 0.45, and 4.5 ppm, respectively. An additional group of adult beetles was immersed in...

Understanding the response of species to anthropogenic landscape modification is essential to design effective conservation programs. Recently, insects have been used in empirical studies to evaluate the impact of habitat modification and landscape fragmentation on biological diversity because they are often affected rapidly by changes in land use. In this study, the use of the landscape matrix...
