The relationship between wing length and body weight of moths was examined based on the samples collected from three mountain areas in southern Korea, Mt. Hallasan (HL), Mt. Jirisan (JR), and Mt.

Many populations of this pest have been documented to be resistant to multiple classes of insecticides in Xinjiang Uygur Autonomous Region of China. Understanding the molecular mechanisms behind resistance in field populations is crucial for making effective strategies for control of this pest. In this study, we investigated potential genetic mutations responsible for insecticide resistance in two insecticidal targets in four cotton aphid populations in Xinjiang. Our data showed that the classical A2′S mutation in the γ-aminobutyric acid (GABA) receptor RDL1 was present in the cotton aphid at frequencies ranged from 4.5 % to 50 %, indicating that the cotton aphids have evolved the Rdl-based mechanism of resistance to synthetic insecticides via a parallel mutation in Rdl1 even in the genetic background with the 2ʹS-carrying duplicated Rdl (Rdl2). In addition, three mutations (A302S, A332V and S431F) in the acetylcholinesterase AChE1 were found to be prevalently distributed in A. gossypii populations. Notably, the resistant 431F allele was fixed in the four examined populations, and all existing ace-1 alleles were resistant, carrying either one or two of the three mutations.

Small heat shock proteins (sHsp) play a vital role in insects responding to external abiotic stress. However, little is known about the role of sHsp in the defense against abiotic stress in S. furcifera. In this study, four sHsp genes (SofHsp20.7, SofHsp21.6, SofHsp21.7, and SofHsp21.8) were identified from S. furcifera, and their gene expression patterns were analyzed at different developmental stages, temperature stress, insecticide exposure, and UV-A irradiation. The results indicated that four sHsp were expressed at various developmental stages of the S. furcifera, with the highest transcription levels in the first-instar nymphs, fourth day fifth instar nymphs, third-day adult females, and eggs, respectively. High-temperature stress (30 °C and 40 °C) significantly induced the expression of all four sHsp genes, while low-temperature stress (10 °C) reduced their expression. Sublethal concentrations (LC10 and LC25) of buprofezin increased the expression levels of SofHsp20.7 and SofHsp21.8. Under UV-A irradiation, the S. furcifera also significantly induced the expression of all four sHsp genes, with the highest expression observed at 90 min after exposure to the stress. These results suggest that sHsp genes are essential for the resistance or tolerance of S. furcifera to high temperature, buprofezin, and UV-A irradiation.

Here we found HvMef2 was highly expressed at the first-instar larvae, 0-day-old second- and fourth-instar larvae, pupae and adults, especially in adult muscle in a Coleopteran potato defoliator Henosepilachna vigintioctopunctata. Injection of 200, 500 or 1000 ng of dsMef2 into the third instar larvae significantly reduced the expression of HvMef2 and impaired larval-pupal-adult transition, in a dose-dependent manner. About 68 %, 77 % and 87 % of the resulting larvae arrested as stunted prepupae, which were gradually blackened and eventually died. Around 32 %, 23 % and 13 % of the HvMef2 depleted beetles formed pupae. Among these HvMef2 depleted pupae, 22 %, 16 % and 7 % became shriveled pupae until death; roughly 10 %, 7 % and 6 % emerged as malformed adults. The growth of the adult thorax muscles was repressed.
