Compatibility of early natural enemy introductions in commercial pepper and tomato greenhouses with repeated pesticide applications
AbstractSuccessful integrated pest management in protected crops implies an evaluation of the compatibility of pesticides and natural enemies (NE), as control strategies that only rely on one tactic can fail when pest populations exceed NE activity or pests become resistant to pesticides. Nowadays in Almer ía (Spain), growers release NE prior to transplanting or early in the crop cycle to favor their settlement before pest arrival because this improves biocontrol efficacy, although it extends pesticide exposure periods. The purpose of this research was to evaluate the compatibility of two application s of pesticides...

Tomato flowers are pollinated by bees that vibrate their thorax for pollen collecting, behavior known as buzz ‐pollination. The phenomenon is common and a specimen of the Neotropical stingless beeMelipona quadrifasciata is here depicted visiting a tomato flower for pollen collecting. While testing whether flower anthers exhibit optimal frequency for pollen release and whether flower bees tune their buzzes to match these frequencies, we recognized that neither bees nor plants are tuned to optimal pollen release frequencies (see pages 133 –142).

Flexible manipulation of Omb levels in the endogenous expression region of Drosophila wing by combinational overexpression and suppression strategy
AbstractManipulating an exogenous or endogenous gene of interest at a defined level is critical for a wide variety of experiments. The Gal4/UAS system has been widely used to direct gene expression for studying complex genetic and biological problems inDrosophila melanogaster and other model organisms. Driven by a given tissue ‐specific Gal4, expressing UAS‐transgene or UAS‐RNAi (RNA interference) could be used to up‐ or down‐regulate target gene expression, respectively. However, the efficiency of the Gal4/UAS system is roughly predefined by properties of transposon vector constructs and the insertion site in t ...

The “sequential cues hypothesis”: a conceptual model to explain host location and ranking by polyphagous herbivores
AbstractSuccessfully locating a host plant is crucial for an insect herbivore to feed and/or oviposit. However, locating a host within a complex environment that may contain an array of different plant species is a difficult task. This is particularly the case for polyphagous herbivores, which must locate a host within environments that may simultaneously contain multiple suitable and unsuitable hosts. Here we review the mechanisms of host selection used by polyphagous herbivores, as well as exploring how prior experience may modify a generalist's response to host cues. We show that recent research demonstrates that polyph...

Alcohol dehydrogenase 5 of Helicoverpa armigera interacts with the CYP6B6 promoter in response to 2 ‐tridecanone
AbstractAlcohol dehydrogenase 5 (ADH5) is a member of medium ‐chain dehydrogenase/reductase family and takes part in cellular formaldehyde and S‐nitrosoglutathione metabolic network. 2‐tridecanone (2‐TD) is a toxic compound in manySolanaceae crops to defend against a variety of herbivory insects. In the broader context of insect development and pest control strategies, this study investigates how a new ADH5 fromHelicoverpa armigera (HaADH5) regulates the expression ofCYP6B6, a gene involved in molting and metamorphosis, in response to 2 ‐TD treatment. Cloning of theHaADH5 complementary DNA sequence revealed that ...

The microbiota in spider mite feces potentially reflects intestinal bacterial communities in the host
AbstractMicroorganisms provide many physiological functions to herbivorous hosts. Spider mites (genusTetranychus) are important agricultural pests throughout the world; however, the composition of the spider mite microbial community, especially gut microbiome, remains unclear. Here, we investigated the bacterial community in five spider mite species and their associated feces by deep sequencing of the 16S rRNA gene. The composition of the bacterial community was significantly different among the five prevalent spider mite species, and some bacterial symbionts showed host ‐species specificity. Moreover, the abundance of t...

Physical contact, volatiles, and acoustic signals contribute to monogamy in an invasive aggregating bark beetle
AbstractThe behavioral strategies and mechanisms by which some insects maintain monogamous mating systems are not well understood. We investigated the mating system of the bark beetleDendroctonus valens, and identified several contributing mechanisms. Field and laboratory observations suggest the adults commonly form permanent bonds during host colonization. Moreover, it showed mated females that remained paired with males produced more offspring than mated females that were alone in galleries. In bioassays, a second female commonly entered a gallery constructed by a prior female. Videos show she commonly reached the locat...

Comparative efficacy of gypsy moth (Lepidoptera: Erebidae) entomopathogens on transgenic blight ‐tolerant and wild‐type American, Chinese, and hybrid chestnuts (Fagales: Fagaceae)
AbstractAmerican chestnut (Castanea dentata [Marsh.] Borkh.) was once the dominant hardwood species in Eastern North America before an exotic fungal pathogen,Cryphonectria parasitica (Murrill) Barr, functionally eliminated it across its range. One promising approach toward restoring American chestnut to natural forests is development of blight ‐tolerant trees using genetic transformation. However, transformation and related processes can result in unexpected and unintended phenotypic changes, potentially altering ecological interactions. To assess unintended tritrophic impacts of transgenic American chestnut on plant&nda...

Contrasting levels of genotype by environment interaction for life history and morphological traits in invasive populations of Zaprionus indianus (Diptera: Drosophilidae)
AbstractIt has been demonstrated that phenotypic plasticity and genotype by environment interaction are important for coping with new and heterogeneous environments during invasions.Zaprionus indianus Gupta (Diptera: Drosophilidae) is an Afrotropical invasive fly species introduced to the South American continent in 1999. This species is generalist and polyphagous, since it develops and feeds in several different fruit species. These characteristics ofZ. indianus suggest that phenotypic plasticity and genotype by environment interaction may be important in this species invasion process. In this sense, our aim was to invest...

Dual roles of juvenile hormone signaling during early oogenesis in Drosophila
AbstractJuvenile hormone (JH) signaling plays crucial roles in insect metamorphosis and reproduction. Function of JH signaling in germline stem cells (GSCs) remains largely unknown. Here, we found that the number of GSCs significantly declined in the ovaries ofMet,Gce andJHAMT mutants. Then we inhibited JH signaling in selected cell types of ovaries by expressingMet andGce orKr ‐h1 double ‐stranded RNAs (dsRNAs) using different Gal4 drivers. Blocking of JH signaling in muscle cells has no effect on GSC numbers. Blocking of JH signaling in cap cells reduced GSCs cells. Inductive expression ofMet andGce dsRNA but notKr ...

Patterns of host cell inheritance in the bacterial symbiosis of whiteflies
AbstractWhiteflies possess bacterial symbiontsCandidatus Portiera aleyrodidium that are housed in specialized cells called bacteriocytes and are faithfully transmitted via the ovary to insect offspring. In one whitefly species studied previously,Bemisia tabaci MEAM1, transmission is mediated by somatic inheritance of bacteriocytes, with a single bacteriocyte transferred to each oocyte and persisting through embryogenesis to the next generation. Here, we investigate the mode of bacteriocyte transmission in two whitefly species,B. tabaci MED, the sister species of MEAM1, and the phylogenetically distant speciesTrialeurodes v...

Involvement of mind the gap in the organization of the tracheal apical extracellular matrix in Drosophila and Nilaparvata lugens
AbstractThe tracheal apical extracellular matrix (aECM) is vital for expansion of the tracheal lumen and supports the normal structure of the lumen to guarantee air entry and circulation in insects. Although it has been found that some cuticular proteins are involved in the organization of the aECM, unidentified factors still exist. Here, we found that mind the gap (Mtg), a predicted chitin ‐binding protein, is required for the normal formation of the apical chitin matrix of airway tubes in the model holometabolous insectDrosophila melanogaster. Similar to chitin, the Mtg protein was linearly arranged in the tracheal dor...
