“…There is considerable evidence that chemosensation is important to host, feeding and oviposition choices made by F. occidentalis . For example, F. occidentalis detects pheromones and prefers specific plant volatiles [56, 57]. In choice tests with diverse tomato cultivars, adult female F. occidentalis preferred fully developed flowers with sepals and petals fully open to those in earlier stages of development and opening, fed preferentially on specific portions of the flower depending on tomato cultivar, and avoided specific acylsugar exudates from Type IV trichomes of tomatoes [58].…”

54Background: The western flower thrips, Frankliniella occidentalis (Pergande), is a globally 55 invasive pest and plant virus vector on a wide array of food, fiber and ornamental crops. While 56 there are numerous studies centered on thrips pest and vector biology, feeding behaviors, ecology, 57 and insecticide resistance, the underlying genetic mechanisms of the processes governing these 58 areas of research are largely unknown. To address this gap, we present the F. occidentalis draft 59 genome assembly and official gene set. 60Results: We report on the first genome sequence for any member of the insect order Thysanoptera. 61 Benchmarking Universal Single-Copy Ortholog (BUSCO) assessments of the genome assembly 62 (size = 415.8 Mb, scaffold N50 = 948.9 Kb) revealed a relatively complete and well-annotated 63 assembly in comparison to other insect genomes. The genome is unusually GC-rich (50%) 64 compared to other insect genomes to date. The official gene set (OGS v1.0) contains 16,859 genes, 65 of which ~10% were manually verified and corrected by our consortium. We focused on manual 66 annotation, phylogenetic and expression evidence analyses for gene sets centered on primary 67 themes in the life histories and activities of plant-colonizing insects. Highlights include: 1) 68 divergent clades and large expansions in genes associated with environmental sensing 69 (chemosensory receptors) and detoxification (CYP4, CYP6 and CCE enzymes) of substances 70 encountered in agricultural environments; 2) a comprehensive set of salivary gland-associated 71 genes supported by enriched expression; 3) apparent absence of members of the IMD innate 72 3 immune defense pathway; and 4) developmental-and sex-specific expression analyses of genes 73 associated with progression from larvae to adulthood through neometaboly, a distinct form of 74 maturation compared to complete metamorphosis in the Holometabola. 75 Conclusions: Analysis of the F. occidentalis genome offers insights into the polyphagous behavior 76 of this insect pest to find, colonize and survive on a widely diverse array of plants. The genomic 77 resources presented here enable a more complete analysis of insect evolution and biology, 78 providing a missing taxon for contemporary insect genomics-based analyses. Our study also offers 79 a genomic benchmark for molecular and evolutionary investigations of other thysanopteran 80 species. 81 KEY WORDS 82 Thysanoptera, western flower thrips, hemipteroid assemblage, insect genomics, tospovirus, 83 virus-vector interactions, salivary glands, chemosensory receptors, opsins, detoxification, innate 84 immunity 85 86 BACKGROUND 87Thrips are small, polyphagous and cosmopolitan insects that comprise the order Thysanoptera. 88Thysanoptera lies within the Paraneoptera, also commonly called the "hemipteroid assemblage" 89 which also includes the orders Hemiptera, Psocoptera, and Phthiraptera. Among the over 7,000 90 reported thrips species classified into nine families with an additional five identified from fossil 91 species [1]...

“…The responses of antennae to synthetic (-)-and (+)-enantiomers of δ-heptalactone revealed that only (-)-δ-heptalactone was EAD active while no response was registered to (+)-δ-heptalactone. Usually, receptors activated by optically active compounds show preferential of varying degrees to one of the enantiomers or respond at a similar level to both enantiomers [24][25][26][27]. Until date, no response to one enantiomer of an enantiomer pair has been reported in limited number of insect species [24,28,29].…”

The plantation area of sea buckthorn (Hippophae rhamnoides L.) is expanding in many European countries due to increasing demand for berries, thus creating suitable conditions for the rapid expansion of the fruit fly Rhagoletis batava, a pest of economic importance. To decrease insecticide use, effective means for pest population monitoring are required, including the use of pheromones. Male fruit flies emit (-)-δ-heptalactone as revealed by gas chromatography-mass spectrometry analyses of samples obtained using headspace methods. The two enantiomers of δ-heptalactone were synthesized using enantioselective synthesis. A gas chromatography-electroantennographic detection analysis of both stereoisomers revealed that only (-)-δ-heptalactone elicited electrophysiological responses, whereas no signal was registered to (+)-δ-heptalactone in fruit flies of either sex. In the field assay, traps baited with (-)-δ-heptalactone caught significantly more fruit flies compared with the unbaited traps. Our results are the first to demonstrate the efficacy of (-)-δ-heptalactone as a bait for trapping R. batava. As a behaviorally attractive compound to R. batava fruit flies of both sexes, (-)-δ-heptalactone is attributed to aggregation pheromones. This is the first report of an aggregation pheromone within the genus Rhagoletis.

Thrips are cause directly damage by laying egg and feeding, indirectly by transmitting tospoviruses on plants. Many factors depending host have important role in plant selection for nutrition, shelter and reproductive. It is known that the first stimulant is host colour and as to second is host odors in host selection. Factors such as the nutrient content and morphological characteristic, different plant parts and also infection status by different organisms indicate changes according to the thrips species which can be influence on the choice of host. The stimulants which effective on host choice are important in determining the strategy of monitoring and control of pest thrips populations. Considering of stimulants that depending on host and combining of them are make more efficient combat with thrips. Specific behavioral features of the thrips reveals necessity of alternative methods and supportive strategies in control of the thrips. In this study, factors that effective on host choice of phytophagous thrips were discussed and evaluated use status of this factors in control of thrips.
