Abstract The bagworm (Thyridopteryx ephemeraeformis (Haworth)) is a polyphagous, native pest of numerous deciduous and evergreen ornamental plants. Bagworm larvae were used to investigate host plant susceptibility among ten species and cultivars of maples that are economically important and commonly encountered in landscapes in the eastern United States. Data analyses from 48-hour choice assays, conducted in the laboratory during 2000 and 2001, indicated that differences existed among maples for bagworm feeding preferences and host plant susceptibility. Results from the 48-hour trials were not as accurate as seasonal no-choice assays, however. No-choice assays during both seasons quantified resistance among maples that limited larval bagworm survival and development. Measurements of larval feeding injury demonstrated resistance in paperbark maple (Acer griseum (Franch.) Pax) and trident maple (A. buergerianum Miq.) when compared with other maples. Laboratory results were corroborated during 2001 by a no-choice field assay, in which early instar bagworm larvae performed well on the majority of maples. In contrast, paperbark maple and trident maple were resistant to bagworm feeding, while ‘Autumn Blaze’ Freeman maple (A. x freemanii E. Murray), a hybrid cross obtained by breeding A. rubrum with A. saccharinum, showed moderate resistance.

It is difficult to associate species of the wood-boring moth in the genus Aenetus with their host plant, because larvae develop inside live trees. A new method is described for rearing larvae of Aenetus eximia, A. lewinii, A. blackburnii, A. ligniveren and A. scotti in cut stems of trees containing larval tunnels by feeding them apple pieces. Larvae that completed development were reared from 49 to 396 days after collection from the field. Aspects of larval feeding webs and adult emergence are described, and new host records are documented. The rearing method is shown to provide an effective means of accurately determining the species of Aenetus developing inside a given host plant.  It was more convenient than obtaining pupae or emerging adults in the field, which is often not possible to do. The method should be useful for conducting surveys, particularly for species with wide distribution ranges. This method may also be effective for the study of other genera of callus feeding, stem boring Hepialidae, such as Archaeoaenetus, Endoclita, Phassus, Schausiana and Zeloptypia.

AbstractThe oviposition preferences of Lygus lineolaris (Palisot de Beauvois) were studied on Brassica carinata A. Braun, Brassica juncea (L.) Czern, Brassica napus L., Brassica rapa L., Sinapis alba L. (high glucosinolates), Sinapis alba L. (low glucosinolates), and Sinapis arvensis L. in a choice test during a 14-day period in field cages. Host-plant discrimination occurred on at least two levels. The first level occurred at the generic level; ovipositing females first selected species of Sinapis on which to lay eggs and later laid on species of Brassica. On species of Sinapis, 80% or more of the total number of eggs were laid during days 1–6, whereas only 35–58% were laid during this period on species of Brassica. The second level occurred at the species level in both Brassica and Sinapis. In Brassica, significantly more eggs were laid on B. carinata and B. napus than on B. juncea; in Sinapis, significantly more eggs were laid on S. alba (high glucosinolates) than on S. arvensis. The numbers of eggs did not differ significantly among B. carinata, B. napus, and S. alba (high glucosinolates). The numbers of eggs on B. rapa and S. alba (low glucosinolate) were not significantly different from those on the other five Brassica and Sinapis hosts tested. Host-plant selection seemed to be unaffected by glucosinolate levels in the seed of S. alba.

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.

AbstractThe suitability of a European moth Anaitis plagiata (L.) for the biological control of the weed Hypericum perforatum L. in British Columbia is evaluated. It is concluded that the introduction of the moth is justified as it offers prospects of reducing the weed density without damage to economic plants. A. plagiata is preadapted to dry habitats and ecologically restricted to them. Its high fecundity and two generations a year should enable it to reach an effective population level rapidly and the early spring feeding by the overwintered larvae should damage the weed when it is most vulnerable. It was shown by feeding tests that the larvae are restricted to plants in the genus Hypericum. Furthermore, all the known hosts of the genus Anaitis are restricted to the genus Hypericum which indicates that the insect-host plant relationship is an old and highly stable one. Larval feeding was found to be partly in response to a chemical compound present in the cuticular waxes of the host plant.

Acraea terpiscore L. is commonly known as the Tawny Coster butterfly, it belongs to the Nymphalidae or Brush-footed butterfly family. Its common larval hosts depend on the availability of Turnera subulata. The study has been carried from January to July 2015 in Thammampatti, Salem district in Tamilnadu. A. terpiscore larvae were found in Turnera subulata and Passiflora foetida. From this observation it is evident that host preference is prevalently exhibited in larval feeding of Tawny Coster. On the availability of T. subulata the choice of P. foetida is found meagre. The caterpillars were counted once a week in both the populations during an observation period of six months. T. subulata and P. foetida plants respectively envisaging its host preference of T. subulata over P. foetida. It is reported here for the first time as a new larval host of Tawny Coster.

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.
