Gall Induction

The molecular-based phylogenetic analysis of the subfamily Tephritinae, the subfamily that contains almost all the cecidogenous species of the family Tephritidae, has reassigned several tribes and groups of genera and modified their concepts based on morphology alone to other tribes and, thus, changed the hypothetical scenarios of evolution of fly/host–plant relations and, in particular, the gall induction in different phylogenetic lineages. Gall induction is shown to arise independently within the Myopitini (in two lineages), Cecidocharini, Tomoplagia group of genera, Eurostini, Eutreta, Tephritis group of genera, Platensinini, Campiglossa group of genera, and Sphenella group of genera independently and more or less synchronously due to the shift to host plants with smaller flower heads and sensitive to larval feeding causing tissue proliferation. This was possibly a result of temporary aridization of the grassy biomes in the Nearctic and Afrotropic regions in the late Miocene or early Pliocene.

Anastrepha Obliqua

Anastrepha obliqua (Macquart) (Diptera: Tephritidae) is an important pest in the neotropical region. It is considered a polyphagous insect, meaning it infests plants of different taxonomic families and readily colonizes new host plants. The change to new hosts can lead to diversification and the formation of host races. Previous studies investigating the effect of host plants on population structure and selection in Anastrepha obliqua have focused on the use of data from the mitochondrial DNA sequence and microsatellite markers of nuclear DNA, and there are no analyses at the genomic level. To better understand this issue, we used a pooled restriction site-associated DNA sequencing (pooled RAD-seq) approach to assess genomic differentiation and population structure across sympatric populations of Anastrepha obliqua that infest three host plants—Spondias purpurea (red mombin), Mangifera indica (mango) of the family Anacardiaceae and Averrhoa carambola (carambola) of the family Oxalidaceae—in sympatric populations of the species Anastrepha obliqua of Inter-Andean Valley of the Cauca River in southwestern Colombia. Our results show genomic differentiation of populations from carambola compared to mango and red mombin populations, but the genetic structure was mainly established by geography rather than by the host plant. On the other hand, we identified 54 SNPs in 23 sequences significantly associated with the use of the host plant. Of these 23 sequences, we identified 17 candidate genes and nine protein families, of which four protein families are involved in the nutrition of these flies. Future studies should investigate the adaptive processes undergone by phytophagous insects in the Neotropics, using fruit flies as a model and state-of-the-art molecular tools.

Fall armyworm, Spodoptera frugiperda is considered an important noctuid moth pest of agricultural crops all over the world and recently become an invasive pest in Pakistan. The crops belonging to Asteraceae, Fabaceae and Poaceae families are highly affected with this pest. The description of host plants is very important in understanding the biology, ecology and application of most effective techniques against the pest. By keeping in view, the importance of this pest, the current study was conducted to evaluate the most preferable host plant such as maize, potato, cabbage, cotton and lehli for this pest in the study area. The results showed that cabbage and maize were the most suitable hosts for larval feeding. The incubation period was recorded 2.00 and 2.12 days on cabbage and maize, respectively. The developmental period of larvae was found longer on cabbage as compared to maize. Potato, cotton and lehli were not found suitable for pest rearing. The study concluded that maize and cabbage are the most suitable hosts for S. frugiperda larvae under natural and controlled conditions.

The cosmopolitan flea beetle genera Phyllotreta and Psylliodes (Galerucinae, Alticini) are mainly associated with host plants in the family Brassicaceae and include economically important pests of crucifer crops. In this review, the host plant associations and geographical distributions of known species in these genera are summarised from the literature, and their proposed phylogenetic relationships to other Alticini analysed from published molecular phylogenetic studies of Galerucinae. Almost all Phyllotreta species are specialised on Brassicaceae and related plant families in the order Brassicales, whereas Psylliodes species are associated with host plants in approximately 24 different plant families, and 50% are specialised to feed on Brassicaceae. The current knowledge on how Phyllotreta and Psylliodes are adapted to the characteristic chemical defence in Brassicaceae is reviewed. Based on our findings we postulate that Phyllotreta and Psylliodes colonised Brassicaceae independently from each other.

In this study, we compare and analyze different ant taxa hindwing morphologies with phylogenetic hypotheses of the Family Formicidae (Hymenoptera). The hindwings are classified into three Typologies based on progressive veins reduction. This analysis follows a revision of the hindwing morphology in 291 extant and eight fossil genera. The distribution of different Typologies was analyzed in the two Clades: Formicoid and Poneroid. The results show a different distribution of Typologies, with a higher genera percentage of hindwings of Typology I in the Clade Poneroid. A further analysis, based on genetic affinities, was performed by dividing the Clades into Subclades, showing a constant presence of hindwings of Typology I in almost all the Subclades, albeit with a different percentage. The presence of hindwings of Typology I (hypothesized as more ancestral) in the Subclades, indicates the genera that could be morphologically more similar to their ancestral ones. This study represents the first revision of the ants’ hindwings, showing an overview of the distribution of different Typologies.

Aeolothrips intermedius is a thrips predator often found in phytocoenoses worldwide. Both the adults and larvae of this species prey on small invertebrates, including phytophagous species from Thysanoptera group. The aim of this study was to determine the morphological variability of the A. intermedius relative to the locality and, indirectly, to the species of host plant. Insects were collected from five localities in southwest Poland and five different host plants. For each of the sexes, six morphometric features were assessed: body length, length of antennae, wing length, head length, head width and length of pronotum. Additionally, the body mass for each individual was estimated. The findings revealed that in females, both the locality and host plant had a significant impact on almost all of these features. In males, the morphometric features under study correlated strongly with locality and only moderately with the host plant. Certain differences were observed between males and females, mainly in terms of antennae length. The results show that A. intermedius exhibits significant variability in this respect, which is indicative of the species’ phenotypic plasticity. The body length was the trait with the most distinct response to the locality and host plant.

The family Fulgoridae is known for their distinct morphological structures and striking colouration. Despite so, comprehensive documentation of insect-plant interaction from this charismatic family is greatly scarce. Presented here are records of plant association across four species of Fulgoridae from Malaysian Borneo. The current study was based on voucher specimens and field samplings from selected localities in Sarawak and Sabah, Malaysian Borneo. A total of 11 species of plants belonging to 11 genera and nine families were recorded. Three fulgorid species namely Penthicodes quadrimaculata, Pyrops intricatus and Py. sultanus shares the same host plant being the mata kucing fruit tree (Dimocarpus longan ssp. malesianus). The most speciose insect-plant association belongs to Pe. farinosa and Py. sultanus with six species documented. This is the first record of host plants reported for Py. intricatus, Pe. farinosa and Pe. quadrimaculata in Malaysian Borneo.   Keywords: Fulgoridae, host plant, insect-plant association, Malaysian Borneo, Sabah, Sarawak

Larval feeding by the Central American ghost moth Phassus n-signatus is recorded in the Asian tree Ligustrum lucidum for the first time. Larval feeding and feeding damage was observed on 15 plants in a suburban environment where L. lucidum is widely used as a residential hedge. Larvae feed under a web of silk and frass on callus wound tissue that grows back following removal of bark around the entrance to a short (less than 42 cm) tunnel where the larva resides when at rest. The diameter of host plant stems at the tunnel site ranged between 4–32 cm and most larval tunnels were found less than 1.5 m from the ground. The presence of P. n-signatus within a suburban residential area shows that this species can persist within human modified urbanized environments where there are sufficient host plants available, and ground conditions include decaying plant debris that would be necessary to support growth of early instars that are presumed to occupy this microhabitat as documented for other stem boring Hepialidae. Key words: callus feeding, Central America, ecology, host plant, larva, phytophagy, stem borer

Wood Boring

Beetles of the family Cerambycidae can girdle stems and larvae bore live or dead stems of their host plants (Linsley 1961), and when they use active tissues (e.g. xylem), can affect the development and survivorship of their hosts (Nowak et al. 2001). Moreover, borer attack can rapidly stress host plants (Matter 2001), often killing them (Nowak et al. 2001). Consequently, they can cause changes in size structure of the plant population, depending on the intensity of attack and plant survival rates (Caraglio et al. 2001). Cerambycids of the genus Oncideres (Lamiinae) present the most specialized behaviour in host-plant use, in which the female cuts stems with its mandibles and prepares the oviposition site above the cut portion by perforating the bark and then inserting eggs (Caraglio et al. 2001, Rice 1989, 1995).

Eriosomatinae is a particular aphid group with typically heteroecious holocyclic life cycle, exhibiting strong primary host plant specialization and inducing galls on primary host plants. Aphids are frequently associated with bacterial symbionts, which can play fundamental roles in the ecology and evolution of their host aphids. However, the bacterial communities in Eriosomatinae are poorly known. In the present study, using high-throughput sequencing of the bacterial 16S ribosomal RNA gene, we surveyed the bacterial flora of eriosomatines and explored the associations between symbiont diversity and aphid relatedness, aphid host plant and geographical distribution. The microbiota of Eriosomatinae is dominated by the heritable primary endosymbiont Buchnera and several facultative symbionts. The primary endosymbiont Buchnera is expectedly the most abundant symbiont across all species. Six facultative symbionts were identified. Regiella was the most commonly identified facultative symbiont, and multiple infections of facultative symbionts were detected in the majority of the samples. Ordination analyses and statistical tests show that the symbiont community of aphids feeding on plants from the family Ulmaceae were distinguishable from aphids feeding on other host plants. Species in Eriosomatinae feeding on different plants are likely to carry different symbiont compositions. The symbiont distributions seem to be not related to taxonomic distance and geographical distance. Our findings suggest that host plants can affect symbiont maintenance, and will improve our understanding of the interactions between aphids, their symbionts and ecological conditions.
