RNA interference of a trehalose ‐6‐phosphate synthase gene reveals its roles in the biosynthesis of chitin and lipids in Heortia vitessoides (Lepidoptera: Crambidae)
In this study, we cloned the trehalose‐6‐phosphate synthase gene (HvTPS) and investigated its expression patterns in various tissues and developmental stages inHeortia vitessoides Moore (Lepidoptera: Crambidae).HvTPS was highly expressed in the fat body and after pupation or before molting. We knocked downTPS inH. vitessoides by RNA interference and found that 3.0  μg of dsHvTPS resulted in optimal interference at 24  h and 36 h post‐injection and caused a sharp decline in the survival rate during the 5th instar larval–pupal stage and obviously abnormal or lethal phenotypes. Additionally, comp...

Aphid populations showing differential levels of virulence on Capsicum accessions
The objective of the current work is to describe in detail different aspects of the interaction between two aphid populations and two selectedCapsicum accessions (one that was susceptible [PB2013046] and one that was resistant [PB2013071] to population NL), including biochemical processes involved. Electrical penetration graph (EPG) recordings showed similar feeding activities for both aphid populations on PB2013046. On accession PB2013071 the aphid population SW was able to devote significantly more time to phloem ingestion than population NL. We also studied plant defense response and found that plants of accession PB201...

Offspring diet supersedes the transgenerational effects of parental diet in a specialist herbivore Neolema abbreviata under manipulated foliar nitrogen variability
AbstractDiet quality influences organismal fitness within and across generations. For herbivorous insects, the transgenerational effects of diet remain relatively underexplored. Using a 3 × 3 × 2 factorial experiment, we evaluated how N enrichment in parental diets ofNeolema abbreviata (Larcordaire) (Coleoptera: Chrysomelidae), a biological control agent forTradescantia fluminensis Vell. (Commelinaceae), may influence life history and performance of F1 and F2 offspring under reciprocal experiments. We found limited transgenerational effects of foliar nitrogen variability among life ‐history traits in both lar...

Construction of an efficient genomic editing system with CRISPR/Cas9 in the vector mosquito Aedes albopictus
AbstractAedes (Stegomyia)albopictus, also known as the Asian tiger mosquito, is a mosquito which originated in Asia. In recent years, it has become increasingly rampant throughout the world. This mosquito can transmit several arboviruses, including dengue, Zika and chikungunya viruses, and is considered a public health threat. Despite the urgent need of genome engineering to analyze specific gene functions, progress in genetical manipulation ofAe. albopictus has been slow due to a lack of efficient methods and genetic markers. In the present study, we established targeted disruptions in two genes, kynurenine hydroxylase (k...

Experimental hybridization and reproductive isolation between two sympatric species of tephritid fruit flies in the Anastrepha fraterculus species group
AbstractAmong tephritid fruit flies, hybridization has been found to produce local adaptation and speciation, and in the case of pest species, induce behavioral and ecological alterations that can adversely impact efficient pest management. Thefraterculus species group withinAnastrepha (Diptera: Tephritidae), is a rapidly radiating aggregate, which includes cryptic species complexes, numerous sister species, and several pest species. Molecular studies have highlighted the possibility of introgression betweenA.fraterculus andA. obliqua. Reproductive isolation has been studied among morphotypes of theA. fraterculus species c...

CRISPR/Cas9 ‐mediated Tyrosine hydroxylase knockout resulting in larval lethality in Agrotis ipsilon
AbstractTyrosine hydroxylase (TH) is involved in insect melanin and the catecholamine biosynthesis pathway. TH as an enzyme catalyzing the conversion of tyrosine to 3,4 ‐dihydroxyphenylalanine is the first step reaction in the pathway. Although TH has been proven to affect the pigmentation of the epidermis and development in many insects, there is no report about physiological function of theTH gene inAgrotis ipsilon. Here we cloned theTH gene fromA. ipsilon. Semi ‐quantitative real‐time polymerase chain reaction (PCR) analysis showed thatAiTH was expressed at all development stages. Moreover, its high expression lev...

Structure and expression of sulfatase and sulfatase modifying factor genes in the diamondback moth, Plutella xylostella
AbstractThe diamondback moth,Plutella xylostella (L.), uses sulfatases (SULF) to counteract the glucosinolate –myrosinase defensive system that cruciferous plants have evolved to deter insect feeding. Sulfatase activity is regulated by post‐translational modification of a cysteine residue by sulfatase modifying factor 1 (SUMF1). We identified 12 SULF genes (PxylSulfs) and two SUMF1 genes (PxylSumf1s) in theP. xylostella genome. Phylogenetic analysis of SULFs and SUMFs fromP. xylostella,Bombyx mori,Manduca sexta,Heliconius melpomene,Danaus plexippus,Drosophila melanogaster,Tetranychus urticae andHomo sapiens showed ...

BmHpo mutation induces smaller body size and late stage larval lethality in the silkworm, Bombyx mori
In this study, we used CRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats/Cas9) to studyHpo gene (BmHpo) function in the lepidopteran insectBombyx mori, known commonly as the silkworm. Sequence analysis ofBmHpo revealed an array of deletions in mutants. We found thatBmHpo knockout resulted in defects in body size regulation, in developmental defects and pigment accumulation and early death. Our data show thatBmHpo is essential for regulation of insect growth and development and that CRISPR/Cas9 technology can serve as a basis for functional analysis of target genes in lepidopteran insects.

Sexual dimorphism in the alpine butterflies Boloria pales and Boloria napaea: differences in movement and foraging behavior (Lepidoptera: Nymphalidae)
AbstractSexual dimorphism is a widespread phenomenon in Lepidoptera. It is reflected in differences in life history, behavior and morphology. Analyses of differences in behavior are mostly difficult and time ‐consuming, especially in high mountain ecosystems. To enhance our knowledge on sexual dimorphisms of alpine butterflies, we performed a mark–release–recapture study on 2 species common in the Alps:Boloria pales andBoloria napaea. We analysed movement and foraging behavior to investigate differences between sexes. Both sexes were mostly sedentary and the movement distances of males and females similar. Ho...

Intraspecific maternal competition induces summer diapause in insect parasitoids
AbstractOrganisms often live in unpredictable environments and have to adopt life history strategies that optimize their fitness under these conditions. According to bet ‐hedging theory, individuals can reduce variation in fitness outcomes by investing in different strategies at the same time. For arthropods, facultative summer diapause enables survival during dry and hot periods of the year, and can be triggered by a decrease in resource abundance. However, the e ffect of resource depletion on diapause induction has never been disentangled from the effect of the perception of the presence of competitors. Using two solit...

Pupal emergence pattern in cactophilic Drosophila and the effect of host plants
We examined the interspecific differences in diurnal temporal patterns of adult emergence from puparia and evaluated whether this behavior is affected by rearing in the different cactus hosts available in nature. We detected important host ‐dependent genetic variation for this trait differentially affecting the emergence schedule of these species. Diurnal pattern of emergence time was directly correlated with developmental time and negatively correlated with adult wing size, suggesting that early emergences are at least indirectly c orrelated with increased fitness.

Hemocyte adhesion to foreign materials is mediated by the cAMP/ protein kinase A pathway and the β‐subunit of cholera toxin using a cAMP‐independent mechanism. Cholera toxin‐induced microaggregation was inhibited by the integrin inhibitory RGDS peptide, implying integrin s may be part of the mechanism. Based on the types of mammalian integrin‐antibody reactive proteins affecting hemocyte adhesion and bacterial‐induced responses α5, αv, β1, and β3 subunits occurr...
