Physiological and gene expression responses of Protohermes xanthodes (Megaloptera: Corydalidae) larvae to imidacloprid.

Megaloptera larvae are important bioindicator species and potential resource insects. To further cultivate their economic role, their living environment must be examined in more detail. In this study, we analyzed the physiological and biochemical effects of a sublethal dose of imidacloprid, a widely used neonicotinoid insecticide, on the larvae of Protohermes xanthodes.

A new genus and a new species of pygmy mole cricket from mid-Cretaceous amber in North Myanmar (Orthoptera: Caelifera: Tridactyloidea).

Gut flora alterations among aquatic firefly inhabiting various dissolved oxygen in fresh water.

Knowledge about the impact of different dissolved oxygen (DO) on the composition and function of gut bacteria of aquatic insects is largely unknown. Herein, we constructed freshwater environments with different DOs (hypoxia: 2.50 ± 0.

Gut microbial diversity and function analysis of the final-instar larvae of Protohermes xanthodes (Megaloptera: Corydalidae).

Protohermes xanthodes (Megaloptera, Corydalidae, Protohermes), widespread species in China, is an important insects treated as food and medicine for aquaculture. In this study, the gut microbiota was investigated by 16S rRNA microbial profiling. A total of 600 Amplicon Sequence Variants (ASV) were identified, Proteobacteria and Firmicutes were the main dominant phyla, and 27 genera ran through the entire digestive tract, mainly Hafnia-Obesumbacterium (Proteobacteria), Lactobacillus and Lactococcus (Firmicutes).

A new species of the genus Burmadactylus Heads, 2009 from mid-Cretaceous amber in north Myanmar (Orthoptera: Caelifera: Tridactyloidea).

This paper describes a new species of the genus Burmadactylus Heads, 2009 (Tridactylidae: Dentridactylinae) from Burmese amber, namely: Burmadactylus tenuicerci sp. nov. This new species is similar to Burmadactylus grimaldi Heads, 2009, but differs from latter by mesotibia basally inflated and almost as long as mesofemur; the second segment of cercus distinctly slender; paraproctal lobe covered with sparse and slender setae, one of the setae near the apex distinct thick and long.

Adults of Alderflies, Fishflies, and Dobsonflies (Megaloptera) Expel Meconial Fluid When Disturbed.

Chemical secretions are an effective means by which insects may deter potential enemies, already being studied extensively with regard to their chemicals, synthesis, toxicity, and functions. However, these defensive secretions have been little studied in Megaloptera. Herein, the fluid expelling behavior of adult alderflies (Sialidae), fishflies (Corydalidae: Chauliodinae), and dobsonflies (Corydalidae: Corydalinae), all of the order Megaloptera, is described in detail regarding the timing and possible function of this behavior.

Two New Species of Ripipterygidae (Orthoptera, Tridactyloidea) from Mid-Cretaceous of Myanmar with a Key to the Genera of Tridactyloidea in Amber.

The abundance of insects in Burmese amber illustrates a highly diverse orthoptera community of the mid-Cretaceous, but the records of ripipterygids are relatively rare. Here, we reviewed the genus of (Xu, Fang and Jarzembowski, 2020) and transfered it from Tridactylidae to Ripipterygidae. Based on four ambers specimens collected from northern Myanmar, two new species, sp.

Physiological Responses of the Firefly (Coleoptera: Lampyridae) to an Environmental Residue From Chemical Pesticide Imidacloprid.

Imidacloprid, a neonicotinoid insecticide, is widely applied to control insect pests across a broad spectrum. Though the impact of residues from this chemical pesticide on non-target organisms in the field has been reported, it was not well characterized across a wide range of ecosystems, especially for some species considered as environmental indicators that live in forests. The effects of sublethal dose of imidacloprid on firefly, , were analyzed physiologically and biochemically in this study to better understand the impact of chemical pesticide application on environmental indicators such as fireflies.

A Chromosome-Level Genome Assembly of the Pygmy Mole Cricket Xya riparia.

The pygmy mole cricket Xya riparia (Orthoptera: Tridactyloidea) is rarely studied or widely known. Some species of pygmy mole crickets, however, not only have a potential ecological value but are also important in the study of the evolution of the orthopteran genome and its phylogenetic relationships. The genome resources of pygmy crickets are limited and there are currently no publications referencing this species' genome.

Do predators prefer toxic animals? A case of chemical discrimination by an Asian snake that sequesters firefly toxins.

Several Asian natricine snakes of the genus feed on toads and sequester steroidal cardiac toxins known as bufadienolides (BDs) from them. A recent study revealed that species of the Group ingest lampyrine fireflies to sequester BDs. Although several species of fireflies are distributed in the habitat of the Group, only lampyrine fireflies, which have BDs, are included in the diet of these snakes.

First report of the Old World leafhopper genus Olidiana McKamey (Hemiptera: Cicadellidae: Coelidiinae) from Pakistan with description of a new species.

This contribution to the taxonomy of Latreille, 1809 (Orthoptera, Tridactyloidea, Tridactylidae) adds descriptions and photographic illustrations of two new species: and from Xishuangbanna, Yunnan Province, China. can be diagnosed by the shiny dark brown hind femora, and the epiproct with a shallow bottom of the middle "v-shaped" crack in the upper part and straight sides; can be diagnosed by the compound eye bearing no narrow band along the inner margin, and the epiproct with the bottom of the side edge with a sharply angled protrusion and a narrow lower anchor-shaped base less than 1/2 the width of the upper one. Distributional information and bionomics for these two new species and photos for the habitat are given.

Dramatic dietary shift maintains sequestered toxins in chemically defended snakes.

Unlike other snakes, most species of possess glands in their dorsal skin, sometimes limited to the neck, known as nucho-dorsal and nuchal glands, respectively. Those glands contain powerful cardiotonic steroids known as bufadienolides, which can be deployed as a defense against predators. Bufadienolides otherwise occur only in toads (Bufonidae) and some fireflies (Lampyrinae), which are known or believed to synthesize the toxins.

Allometry and morphological trait relationship in the sexually dimorphic Chinese dobsonfly, (Wood-Mason, 1884) (Megaloptera, Corydalidae).

Male insects with large weapons such as horns and elongate mandibles would be expected to invest more on such structures than other parts of the body for advantages in male to male competition for mating. In male genitalia, however, intermediate size provides a better fit for more females than small or large sizes, and such a male would leave more offspring regardless of their body size. These predictions were tested using a static allometry analysis between body size and other trait sizes.
