Most important that comes out of it is the finding of an exact time of occurrence of a dead body by estimating the post-mortem interval (PMI). Our study focused on blow fly pupae, which are some of the earliest insects to colonize decomposing bodies. The pupae of the blow fly have the longest development period in the blow fly life history, but we have trouble viewing the inside of the pupae because of the puparium. It is, therefore, a developmental internal X-ray imaging stage carried out to see if such a division experiment could reveal a difference in growth based on temperatures in two different temperatures. All experiments were recorded accurately with an indoor Wi-Fi camera. Finally, the sampling individual in 20 °C and 30 °C shows a significant difference at the developmental time of 10,640 min and 5470 min, respectively. As the internal developmental stage at two different temperatures, it distinctly delimited based on their morphological characteristics. The internal developmental stages, identified by morphological characteristics, were subdivided into four distinct phases, improving the precision of post-mortem interval estimation. In this study, we attempted to delimit the pupae into developmental instars based on internal development with the help of X-ray imaging.

Phytochemicals offer environmentally safe, biodegradable, and targeted pest management. Nanostructure lipid carriers (NLCs), a second generation of solid lipid nanoparticles, are gaining attention as potential diagnostic and therapeutic tools. Sesbania leaves, rich in fatty acids, phenolics, and terpenes, were analyzed using gas chromatography–mass spectrometry. Magnetic nanoparticles (Se-NLC-MNPs) modified the surface of Sesbania extract, encapsulated in the NLC. The resulting nanoparticles were 129.2 and 218.5 nm in size, with zeta potentials of −6.20 and 43.9 mV, respectively. Transmission electron microscopy showed spherical and oval shapes. XRD patterns confirmed the successful decoration of the NLC with the magnetic nanoparticles.

Se-NLC-MNPs showed higher larval mortality rates compared to their Se formulation extracts, achieving 100% mortality in third-instar larvae.

To understand the physiological response of honey bees caused by inappropriate exposure to miticides, it is necessary to identify the marker genes whose expression alters in honey bees following exposure to miticides. Although quantitative real-time polymerase chain reaction (qRT-PCR) is widely used for gene expression analysis, selecting appropriate stably expressed reference gene(s) across various conditions is essential for accurately determining target gene expression levels. Therefore, this study assessed the expression stabilities of 10 candidate reference genes (<i>RPS5</i>, <i>RPS18</i>, <i>GAPDH</i>, <i>ARF1</i>, <i>RAB1a</i>, <i>PPI</i>, <i>PGK</i>, <i>SDH</i>, <i>TBP</i>, and <i>EF1</i>) using C<sub>q</sub> distribution and four algorithm programs (NormFinder, BestKeeper, geNorm, and RefFinder). Subsequently, we validated various normalization methods using each of the 10 reference genes and a combination of multiple genes by calculating the expression of the target gene (<i>SOD2</i>).

This study evaluates the pathogenicity of <i>M. flavoviride</i> Ma130821 against larvae of <i>Metabolus flavescens</i> Brenske feeding on maize and tobacco, respectively, and examines the infection process and aspects of the host immunological response. The present results showed that <i>M. flavoviride</i> Ma130821 caused 76.67%–100.00% mortality of <i>M. flavescens</i> larvae within 18 days. When hyphal bodies infected the hemocoel of a host, this strain inhibited the normal protein metabolism through the consumption of protein nutrients and then activated the immunity by increasing the amounts of hemocytes. The infection also initiated the humoral immunity response by increasing the content and enzymatic activity of phenoloxidase (PO). After inoculation, the content and enzymatic activity of PO presented a significant increase and reached the peaks at 72 or 96 h after inoculation (HAI), indicating that immune responses of hemolymph in infected larvae were more intensive at middle/late stage of infection. However, the growth of hyphal bodies was not recognized by the host's immune system as invaders when they reached a high density. The amount of total hemocyte and the content and enzymatic activity of PO all decreased significantly. <i>M. flavoviride</i> Ma130821 appears to affect the larvae's immune system and results in decreased immunity.

From 2022 to 2023, we conducted investigations at 15 locations where pin oak trees were planted. We performed visual inspections on branches and trunks within 5 m height of trees to record insect pest presence and damage characteristics, using pruning poles to sample branches when needed. As a result, various taxa, mainly Lepidoptera, Hemiptera, and Coleoptera, were identified, and densities of pests varied depending on the planted environment. In the central region of South Korea, the predominant or important species were wood-boring insect pests such as clearwing moths (Cossidae) and longhorn beetles (Cerambycidae).

Among six different environments, the largest number of pests was found in parks and followed by street, riverside, tree market, etc. These results suggest that pest monitoring and management strategies tailored to specific regions and environments are necessary when planting pin oak trees.

When exposed to low temperatures for 1–24 h at a temperature of 0°C to −10°C, the diapause eggs had a hatching rate higher than that of nondiapause eggs in all sections. The difference in hatching rate according to temperature, exposure time, and diapause status was all considered significant at −6°C or less (two-way ANOVA). A significant regression equation was calculated to estimate the hatching rate, a dependent variable (<i>R</i><sup>2</sup> = 0.439, <i>p</i> &lt; 0.000). We found a significant difference in hatching rates for low-temperature stress between diapause eggs and nondiapause eggs of <i>Ae. albopictus</i>, which may explain why <i>Ae. albopictus</i> spreads in high-latitude regions. The morphological differences between diapause and nondiapause and variables such as dryness and light intensity should be studied to understand the overwintering of <i>Ae. albopictus</i>.</p>\u0000 </div>","PeriodicalId":11776,"journal":{"name":"Entomological Research","volume":"55 2","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
