Seasonal Abundance and Diversity of Biting Midges in Livestock Sheds in Kanchanaburi Province, Thailand.

biting midges were collected using UV light traps from nine livestock farms in Kanchanaburi Province, Thailand. Collections were made one night per month from June 2020 to May 2021 to determine the seasonal changes and spatial distribution of the assemblage. The influence of four environmental factors (temperature, rainfall, humidity, and wind speed), types of animals in each shed (cattle, pigs, and avians), and neighboring animals (those in the other sheds and their proximity) were assessed.

Comprehensive Investigation of Die-Back Disease Caused by in Durian.

Durian ( L.) is an economically important crop in the southern and eastern parts of Thailand. The occurrence of die-back disease caused by plant pathogenic fungi poses a serious threat to the quality and quantity of durian products.

A new species and a new synonym in the scarab genus Parastasia Westwood, 1841 (Coleoptera: Scarabaeidae: Rutelinae), with a key to species from Thailand.

Ten species of the genus Parastasia Westwood, 1841 including a new species and a new record are recorded from Thailand. We here describe Parastasia spinosa Hongsuwong, Sanguansub & Jaitrong, new species from eastern Thailand based on a male specimen. Parastasia bimaculata (Guérin-Méneville, 1843) is recorded for the first time in Thailand.

Geometric Morphometric Analysis and Molecular Identification of Coconut Mite, Keifer (Acari: Eriophyidae) Collected from Thailand.

One of the most impactful pests in several coconut production regions across the world is the coconut mite, Keifer. Scholars can obtain some necessary biogeographic information about coconut mites from studies that explore the geographic patterns of morphological variations and molecular properties among coconut mite populations from various locales. To investigate the geographical origin, ancestral host associations, and colonization history of the mite in Thailand, we obtained DNA sequence data from two mitochondrial (16s and COI) and one nuclear region (ITS) from coconut mite samples originating from 25 populations; additionally, we analyzed the morphological variations in the prodorsal shield and the coxigenital and ventral regions of the mite idiosoma.

Mechanisms of Trichomes and Terpene Compounds in Indigenous and Commercial Thai Rice Varieties against Brown Planthopper.

Plant trichomes generally act as a physical defense against herbivore attacks and are present in a variety of plants, including rice plants. This research examined the physical and chemical defenses of rice plants against the brown planthopper (BPH), (Stål) (Hemiptera: Delphacidae). A total of 10 rice varieties were used in this study.

Morphological and Molecular Identification of Plant Pathogenic Fungi Associated with Dirty Panicle Disease in Coconuts () in Thailand.

Dirty panicle disease in coconuts () was first observed in the KU-BEDO Coconut BioBank, Nakhon Pathom province, Thailand. The occurrence of the disease covers more than 30% of the total coconut plantation area. The symptoms include small brown to dark brown spots and discoloration of male flowers.

Revision of the genus Xylodrypta Lesne 1901 (Coleoptera: Bostrichidae: Bostrichinae: Xyloperthini) with a new species and a key to species.

We revise the monospecific bostrichid genus Xylodrypta Lesne 1901, and describe a new species, X. lanna Liu Beaver from Thailand and Laos. A key is given to distinguish the two species of Xylodrypta.

Parasitism of Soldiers of the Termite, (Hagen), by the Scuttle Fly, (Loew) (Diptera: Phoridae).

Termites of the genus (Termitidae: Macrotermitinae) are serious agricultural and structural pests, which also play vital roles in ecosystem functioning, and are crucial for the maintenance of tropical biodiversity. They are widely distributed, mainly in Southeast Asian countries; however, the parasitism of termites has been little researched. This research was conducted to identify and study the ecology of the parasitoids of termites at Kasetsart University, Kamphaeng Saen Campus, Nakhon Pathom, Thailand.

A review of the genus Dryocoetiops Schedl, with new species, new synonymy and a key to species (Coleoptera: Curculionidae: Scolytinae).

Eighteen species currently placed in the genus Dryocoetiops Schedl, 1957, are reviewed. Two new species are described: Dryocoetiops pasohensis Beaver, Smith and Sanguansub, D. salebrosus Beaver, Smith and Sanguansub.

A new species of Lobesia Guenée, 1845 from Thailand (Lepidoptera: Tortricidae: Oletheutinae).

Lobesia bisacca Charoensub and Pinkaew, n.sp., is described from Thailand.

An annotated checklist of Platypodinae and Scolytinae (Coleoptera: Curculionidae) from Iran.

We provide an annotated checklist of species of bark and ambrosia beetles (Curculionidae: Platypodinae and Scolytinae) recorded from Iran, with information on distribution, host trees, biology and taxonomy. Two species of Platypodinae and 79 species of Scolytinae are recorded. Hypothenemus crudiae (Panzer, 1791), Scolytus koenigi Schevyrew, 1890 and Xyleborus monographus Fabricius, 1792 are recorded for the first time from Iran.

A review of the genus Carchesiopygus Schedl (Coleoptera: Curculionidae: Platypodinae), with keys to species.

The ten species included by Schedl (1972) in the Oriental platypodine genus Carchesiopygus Schedl are reviewed. The genus is rediagnosed and restricted to the following species: Carchesiopygus wollastoni (Chapuis) (type species), C. alternantes Schedl, C.

Comparison of Sapwood Discoloration in Fagaceae Trees After Inoculation with Isolates of Raffaelea quercivora, Cause of Mass Mortality of Japanese Oak Trees.

The mass mortality of oak trees has been prevalent in Japan since the late 1980s. The fungus Raffaelea quercivora is transmitted by an ambrosia beetle, Platypus quercivorus, which causes mortality. The beetle is able to bore galleries into the sapwood of most Fagaceae trees in Japan; however, the level of mortality caused by R.
