Abstract The codling moth Cydia pomonella , a major invasive pest of pome fruit, has spread around the globe in last half century. We generated chromosome-level scaffold assembly including Z chromosome and portion W chromosome. This reveals duplication an olfactory receptor gene ( OR3 ), which we demonstrate enhances ability C. to exploit kairomones pheromones locating both host plants mates. Genome-wide association studies contrasting insecticide-resistant susceptible strains identify...
Thermal adaptation plays a fundamental role in the expansion and distribution of insects, heat shock proteins (Hsps) play important roles temperature various organisms. To determine Hsp genes (Hsp70, Hsp21, sHsp21) on high tolerance Agasicles hygrophila, we obtained complete cDNA (complementary DNA) sequences for Hsp70, sHsp21 by rapid amplification ends (RACE), analyzed their expression profiles under different treatments quantitative reverse transcription polymerase chain reaction...
Heat shock proteins are molecular chaperones that involved in numerous normal cellular processes and stress responses, heat factors transcriptional activators of proteins. coordinated various biological processes. The regulatory function the expression genes encoding (Hsps) has been documented some model insects, however, role transcription modulating Hsps other insects is still limited. In this study, one factor gene (AhHsf) was isolated its two potential target (AhHsp70 AhsHsp21) were...
Agasicles hygrophila Selman and Vogt is used in the biological control of invasive weed Alternanthera philoxeroides (Mart.) Griseb. However, with northward establishment A. China, weak adaptivity to cold weather has resulted ineffective northern China. Cold acclimation can significantly enhance insect tolerance, enabling them cope more frequent climate fluctuations. To improve efficacy climates, we compared effects rapid hardening on under laboratory conditions. On initially transferring...
The alligatorweed flea beetle Agasicles hygrophila is an insect used for biological control of the aquatic weed Alternanthera philoxeroides (alligatorweed). Because these insects are oviparous, synthesis and transportation yolk proteins integral to reproduction. Vitellin, chief protein constituent in egg yolk, mainly synthesized fat body its regulated by transcript levels Vitellogenin (Vg). In our study, we first cloned characterized three Vg genes from A. quantified expression Vgs different...
Agasicles hygrophila is an effective biological control agent for the invasive weed Alternanthera philoxeroides, and because of this it has been introduced to many parts world where A. philoxeroides a problem. Despite this, there are no reports at present about reproduction important insect. Vitellogenin receptors (VgRs) belong superfamily low-density lipoprotein (LDLRs). One roles VgRs regulate absorption yolk protein in insects. In study, full length vitellogenin receptor gene (AhVgR) from...
Agasicles hygrophila is a classical biological agent used to control alligator weed (Alternanthera philoxeroides). Previous research has indicated that the heat shock factor (HSF) involved in regulating transcriptional expression of Hsp70 response resistance A. hygrophila. However, regulatory mechanism by which AhHsf regulates AhHsp70 remains largely unknown. Here, we identified and cloned 944 bp promoter (AhHsp70p) region from Subsequent bioinformatics analysis revealed AhHsp70p sequence...
Understanding the host-selection behavior of herbivorous insects is important to clarify their efficacy and safety as biocontrol agents. To explore host-plant selection beetle Ophraella communa, a natural enemy alien invasive common ragweed (Ambrosia artemisiifolia), we conducted series outdoor choice experiments in cages 2010 open fields 2011 determine preference O. communa for A. artemisiifolia three non-target plant species: sunflower (Helianthus annuus), cocklebur (Xanthium sibiricum),...
Agasicles hygrophila , a leaf-feeding Chrysomelid beetle, was introduced into China in 1986 as biological control for Alternanthera philoxeroides (alligatorweed), noxious perennial invasive weed. However, Hunan’s Ag. populations decrease suddenly during summers (at high temperatures), leading to the inefficient of alligatorweed. To investigate this phenomenon, herein, effects four different temperatures (26, 30, 36, or 39°C) on reproductive capacity and egg-hatch, pupation, eclosion, adult...
Alligator weed Alternanthera philoxeroides is a perennial, worldwide pernicious weed. The beetle Agasicles hygrophila considered to be classical biological agent used control A. . In the insect peripheral olfactory system, odorant receptor co-receptor (ORco) plays an important function in perception of odors insects. However, ORco mating and host-finding behaviors remains unclear. this study, we characterized ( AhygOrco ). Real-time quantitative PCR (qRT–PCR) showed that was predominantly...
Alternanthera philoxeroides (Amaranthaceae), commonly known as alligator weed, is a globally invasive and detrimental perennial weed. Agasicles hygrophila serves an important biocontrol agent for weeds. However, during mid-summer, when temperatures increase, A. populations experience significant decline, leading to ineffective weed control. This study has examined the impact of periodic heat events on reproduction survival females males using various mating combinations durations temperature...
In insects, ecdysteroids are synthesized by genes of the Halloween family and play important roles in several key developmental events, including molting metamorphosis. However, these Agasicles hygrophila still largely unknown. this study, expression patterns two AhCYP307A2 AhCYP314A1 were determined quantitative PCR (qPCR) at different stages. Moreover, functions explored using RNA interference (RNAi), ovarian development was observed dissecting ovaries A. females. The qPCR results showed...
