“…Bach () first reported the relative lack of movement in the adult CPB compared with other specialist chrysomelid beetles such as the striped cucumber beetle, Acalymma cittata (Fabricius). Adult CPB tend to remain on a potato plant for some time after its colonization before dispersing to other potato plants (Bach, ; Boiteau & MacKinley, ). The dominant role of the host plants could also explain why the different CPB emigration rates observed by Schmera et al.…”

“…Bach (1982) first reported the relative lack of movement in the adult CPB compared with other specialist chrysomelid beetles such as the striped cucumber beetle, Acalymma cittata (Fabricius). Adult CPB tend to remain on a potato plant for some time after its colonization before dispersing to other potato plants (Bach, 1982;Boiteau & MacKinley, 2013). The dominant role of the host plants could also explain why the different CPB emigration rates observed by Schmera et al (2007) between non-host habitats (greater in wheat-covered ground than in fallow ground) became similar, when Szendrei et al (2009) added potato plants to the otherwise non-host habitats (rye, vetch covered soil, or otherwise bare ground).…”

“…The dispersal of adult CPB throughout this agro-ecosystem is achieved through a combination of bouts of walking and flight (Gibson et al, 1925;Noronha & Cloutier, 1999;Boiteau et al, 2003;MacQuarrie et al, 2004). Although there is some understanding of seasonal dispersal (Weber & Ferro, 1994;Noronha & Cloutier, 1999;Baker et al, 2001;Boiteau & Heikkila, 2013), host colonization (French et al, 1993;Blom et al, 2004;Boiteau & Heikkila, 2013), host residency (Bach, 1982;Boiteau & MacKinley, 2013), and emigration (sensu Sk orka et al, 2013) from host patches (Weber & Ferro, 1994;Schmera et al, 2007), dispersal from non-host or non-crop habitats has received little attention. Weber & Ferro (1994) reported a disappearance rate of overwintered beetles of 77% from fallow areas compared with 54% from potato 4 days after release.…”

“…Schmera et al (2007) reported lower CPB emigration rates from wheat than from fallow ground in the absence of hosts. These studies and the longer residency period on hosts than on non-hosts (Bach, 1982;Boiteau & MacKinley, 2013) suggest that beetles move out of non-host habitats at higher rate than from host habitats.…”

The walking and flight dispersal of marked overwintered and summer Colorado potato beetles (CPB), Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), released in field box‐plots was monitored simultaneously in six habitats over a period of 4 days. The emigration out of plots by walking beetles was calculated from the catch in linear pitfall traps completely surrounding each box‐plot and emigration flight was estimated from the number of beetles missing from the plot or captured by the trap. Overwintered beetles dispersed sooner after release than summer beetles. Overall, the mean number of beetles retained by the habitat was significantly higher in the host habitat (potato) than in any non‐host habitat tested (soybean, pasture, bare ground, water, woodland). Unexpectedly, there was no or little difference in overall beetle retention between non‐host habitats except for higher retention in the water habitat. No difference in the ratio of flight over walking could be detected by the study between overwintered and summer CPB except in the water and woodland habitats. Twenty‐four hours after release, the highest ratios were obtained in the water and woodland habitats and the lowest in the bare‐ground habitat, but ratios were similar for all habitats, except water, after 96 h. As a population, under these experimental conditions, 96 h after release, it seems that CPB displayed a slight preference for flight over walking, with walking as a default mode. A fed and starved pre‐release treatment had no effect on dispersal rates or mode of dispersal. Essentially, our results showed that over a 96‐h period, northeastern North American CPB emigrated at similar rates from the various non‐host habitats encountered, except for water, using walking as much as flight. The host habitat retained CPB significantly longer than non‐host habitats but with a mode of dispersal ratio similar to that in non‐host habitats. The impact on dispersal of the various habitats encountered by CPB in the agro‐ecosystem was less important than expected suggesting that the interaction of environmental parameters is likely to have the most significant impact in determining dispersal rates and dispersal modes.

“…In the case of the CPB, there is evidence that adults tend to remain on a potato plant for some time after its colonization before dispersing to other potato plants [15], [16]. The trends reported in Bach [15] emphasize the relative lack of movement in the adult CPB compared to other specialist chrysomelids such as the striped cucumber beetle, Acalymma cittata (Fab.).…”

Impact of Host Plant Connectivity, Crop Border and Patch Size on Adult Colorado Potato Beetle Retention

Tagged Colorado potato beetles (CPB), Leptinotarsa decemlineata (Say), were released on potato plants, Solanum tuberosum L., and tracked using a portable harmonic radar system to determine the impact of host plant spatial distribution on the tendency of the pest to remain on the colonized host plant or patch. Results confirmed the long residency time on the host plant and showed that close connection of the plant to neighboring plants hastened dispersal between plants. Tracking walking CPB for over 6 h in small potato plots revealed that all types of mixed borders tested (potato/bare ground, potato/timothy and potato/woodland) acted as a strong barrier and retained beetles within the patch. In another experiment in potato patches surrounded by bare ground borders, tracked walking CPB displayed similar behaviour for up to four days. The distribution of turning angles in the CPB walking paths was not uniform and corresponded to beetles following the edge rows of potato patches in response to the crop border barrier or reversing their direction as they reached the end of a row and therefore a border. Patch size had no or little effect on beetle retention in the patch. The relative distribution of counts of tagged beetles detected among small (16 m2), medium (64 m2) and large size (256 m2) patches of potato four days after initial release remained similar to that of numbers released. Even though mixed crop borders were a strong barrier to walking CPB emigrating from potato patches, the departure rate of beetles over time was high. Results suggest that the effect of mixed borders is largely limited to dispersal by walking and does not apply to beetles leaving host patches by flight. The manipulation of crop borders and patch size seem to have limited potential for the management of CPB emigrating from potato fields.
