“…How this species evaluates occupancy is not fully understood. Herbivory combined with beetle presence attracts other adults, suggesting that plant volatiles and pheromones are involved (Peacock et al 2001), but other cues might also help determine occupancy (Fernandez andHilker 2007, Dicke andBaldwin 2010). Early eggs probably contributed more to the final number of eggs on a plant than later eggs because females probably laid fewer eggs as they encountered more eggs on a plant over the course of the experiment.…”

“…Both the direct perception of eggs and indirect cues could inform females about the occupancy of a plant by conspecifics. Sex pheromones, aggregation pheromones, feces, and larval defense secretions (Fernandez and Hilker 2007), as well as induced plant volatiles (Dicke and Baldwin 2010), play important roles in determining host suitability and likely affect aggregation behavior. At the same time, insects are able to learn and memorize, but most studies deal with ants, bees, parasitoid wasps, fruit flies, and grasshoppers (Dukas 2008, Wright andSchiestl 2009).…”

How far away is the next basket of eggs? Spatial memory and perceived cues shape aggregation patterns in a leaf beetle

Abstract. Gregarious organisms need to handle the trade-off between increasing food competition and the positive effects of group living, and this is particularly important for ovipositing females. We hypothesized that insect females consider how many conspecifics previously visited a host plant. In a no-choice assay, we show that the gregarious blue willow leaf beetle (Phratora vulgatissima) laid the most eggs and the largest clutches on plants where a sequence of few individual females was released, compared to plants where one or many different females were repeatedly released. Therefore, this species is more sensitive to the indirectly perceived number of conspecifics than the directly perceived number of eggs on a plant. We further hypothesized that females adjust their own intra-plant egg clutch distribution to that of conspecifics and discovered a new behavioral component, i.e., the modulation of distances between clutches. Females adjusted these distances in ways indicating the use of spatial memory, because the largest distance increases were observed on plants with their own clutches, compared to plants with clutches from conspecifics. However, adjustment of aggregation level and distance between clutches occurred only on a suitable, and not on an unsuitable, Salix genotype. We conclude that both behaviors should reduce competition between sibling and non-sibling larvae.

“…The results of our study also suggest that host plant data are under reported in the literature, possibly a product of sampling a narrower range of plant families and hispine tribes (Jolivet, 1997;Fernandez and Hilker, 2007). Laboratory feeding trials will be essential to know just how accurately occurrence data as presented in this study reflect actual feeding habits of hispines (Descampe et ah, 2007, in press).…”

Abstract. The feeding traces in fossil ginger leaves and the conserved phylogenetic relationships seen today in certain clades of hispine beetles on their monocot hosts point towards a long and intimate plant-insect evolutionary relationship. Studies in the 1970s and 1980s documented the rich fauna of rolled-leaf hispine beetles and their association with the Neotropical monocot family Heliconiaceae in Central America. In this report, the taxonomic breadth of these early studies is expanded to include species in the families, Marantaceae, Poaceae, Arecaceae and Costaceae, all with species occurring sympatrically with the Heliconiaceae in lowland Panama. Additionally, the analysis is widened to include open-leaf scraping and internal leaf-mining clades of hispoid Cassidinae. The censuses add more than 5080 Cassidinae herbivore occurrence records on both open and unfurled new leaf rolls of 4600 individual plants. Cluster analysis reveals that while many Hispinae species tend to group with plant species in only one of the three monocot orders, 9 of 16 Hispinae species on Zingiberales hosts were recorded in substantial numbers on both the Heliconiaceae and the Marantaceae, indicating an underlying pattern of feeding flexibility at the host plant family level.

The Colorado potato beetle (CPB) is one of the pest insects that significantly can decrease the production of potato when no control measures are taken. The fast, flexible and diverse life cycle of the CPB, its highly destructive feeding habits, and high adaptability to a variety of environment stresses, have made the control of CPB a difficult task. This paper briefly reviews the information on all aspects of CPB management to come to an integrated pest management approach: the biology of the CPB, management practices including their limitations and drawbacks, as well as the need to incorporate host plant resistance into potato varieties. Several aspects of potato breeding for resistance to CPB are discussed. We evaluate the availability of natural variation present in potato wild relatives, the considerations in choosing a specific wild relative, and constraints in using them from biological, environmental and genetic point of view, in which newly developed technologies play an important role. We also consider recently developed GM approaches. We conclude that varieties resistant to CPB are desperately needed by farmers and demanded by society, and that the means to develop them are available.
