Coccinella minneapolis3/28/2023 ![]() ![]() revealed the diapause-related functions of several genes involved in fatty acid biosynthesis and lipid accumulation in C. We identified several specifically expressed genes and proteins involved in lipid storage, energy metabolism, and hormonal signaling pathways. We also found a conspicuous series of changes in diapausing females at the proteomic and transcriptomic levels. These physiological changes provide the energy required by the insect to get through the diapause period, and thus survive under hostile environmental conditions. septempunctata in diapause exhibit arrested ovarian development, increased lipid accumulation and higher cold tolerance. septempunctata adult at the diapause induction condition of 18 ☌, L10:D14. Moreover, our previous studies demonstrated that the first 20 days after eclosion is the pre-diapause stage of C. Our previous work indicates that the specific sensitive period for diapause-inducing in the ladybird is the new adults stage (newly emerged). septempunctata adults enter winter diapause in response to short photoperiods and low temperatures. septempunctata can enter diapause in the summer or winter. Depending on the geographical distribution of distinct populations, adults of C. In Europe, Asia, and North America, this natural enemy has been commercially mass-cultured and widely employed in greenhouses and farmlands. As a typical natural predator of agricultural pests, the ladybird beetle, Coccinella septempunctata (Linnaeus), is economically important for controlling aphids, whiteflies, mites, thrips, and lepidopteran pests. Natural predators are important for pest control in agricultural systems. septempunctata during the diapause preparation stage. The results suggested that the CsCatL gene was involved in fatty acid biosynthesis and played a crucial role in the survival of adult C. spetempunctata under diapause-inducing conditions. Furthermore, silencing the CsCatL gene distinctly reduced diapause-related features and the survival of female C. Knockdown of CsCatL by RNA interference led to decreased expression levels of fatty acid synthase 2 (fas 2) genes and suppressed lipid accumulation. It was identified as the cathepsin L group by phylogenetic analysis. The cDNA sequence of CsCatL was 971 bp in length, including an 843 bp open reading frame encoding a protein of 280 amino acids. CsCatL was cloned and identified from beetle specimens by rapid amplification of cDNA-ends (RACE). septempunctata and its role during the diapause of the ladybeetle. Here, we analyzed the characteristics of cathepsin L ( CsCatL) in the females of C. ![]() However, little was known about the role of cathepsin L in ladybird beetles ( Coccinella septempuctata Linnaeus) during diapause. Cathepsin L protease, which belongs to the papain-like cysteine proteases family, is an important player in many physiological and pathological processes. ![]()
