“…Moreover, seedlings of trees are either planted or occur naturally in both clear-cut and salvage-logged areas. The new habitats created after such anthropogenic disturbances are very similar to those created after natural disturbances: both are short-lived and remain suitable for open-area species for several years (Southwood 1962;Travis and Dytham 1999).…”

I investigated the ecological consequences of disturbances (anthropogenic and natural) on the scuttle fly communities in four large Pine Forests in Poland. I used data on 17,547 male individuals representing 183 species. Communities found in pine plantations (established in clear-cut areas) and in differently treated post-windstorm (with windthrow logs being left or removed) were less diverse than those found in old-growth forest. The communities recorded in the same habitat types in different forest complexes (ca. 300 km apart) were found to display greater similarity than those recorded on adjacent plots in a given forest (ca. 1 km apart), but covering different habitats. The species-specific preference for habitats after disturbances (clear-cuts and post-windstorm areas) was highly correlated between the forests. The abundance of the species with saprophagous larvae was distinctly higher in the disturbed areas than in the old-growth stands. Also, the body length of the scuttle flies was significantly related to their preference for disturbed or undisturbed habitats: smaller species preferred clear-cuts and post-windstorm areas, whereas larger species were related to intact stands.

“…Timing of migration to begin during the longer oviposition period, rather than being confined to the much shorter pre-oviposition period, may improve the flexibility of this life history strategy in the face of uncertain environmental conditions. It would extend the option for individuals to escape unfavorable conditions and to exploit new habitat across a wide temporal window (Southwood, 1962;Lidicker and Caldwell, 1982;Rankin and Singer, 1984). Unlike migratory insects exhibiting the oogenesis-flight syndrome (Rankin et al, , 1994Colvin and Gatehouse, 1993;Keil et al, 2001;Gu et al, 2006;Lorenz, 2007), we hypothesize that S. exigua pursues multiple matings during the migratory phase and that it oviposits part of its eggs en route.…”

The beet armyworm, Spodoptera exigua, undertakes long-distance migration. We used flight mills to investigate the interaction between flight and reproduction in this species given the apparent absence of the oogenesis-flight syndrome. This syndrome, common in many migratory insects, is characterized by a suite of traits including migration during the pre-oviposition period followed by a switch to oogenesis. No negative effects of inter-ovipositional flight on lifetime fecundity were observed. Instead, adult reproductive output suffered when female flight was initiated the first day after eclosion and before oviposition, suggesting that migratory flight overlaps with the oviposition period rather than being confined to the pre-oviposition period. Mating status of both females and males had no negative influence on their flight performance except that flight distance and flight duration of 7-day-old mated females were significantly less than in unmated females. Furthermore, the number of eggs produced and mating frequency of females less than 7 days of age were not significantly correlated with flight performance, suggesting reproductive development paralleled and was independent of migratory behavior. This independent relationship between flight and reproduction of adults is consistent with the very short pre-oviposition period in this species, and suggests that resources are partitioned between these activities during pupal development. Together, our results uncovered neither obvious trade-offs nor mutual suppression between flight and reproduction in S. exigua, which indicates the lack of an oogenesis-flight syndrome for coordination of these two energy-intensive processes. We propose a conceptual model of migration for this species based on the current and previous studies.

“…This is an interesting phenomenon as it might reveal a synchronous behavior in Uranotaenia sp. mosquitoes, probably related to dispersal as observed in other insects (Southwood 1962) and that deserves further study.…”

Larvae of the mosquito Uranotaenia novobscura ryukyuana Tanaka et al., have been reported in tree-holes, bamboo stumps, and artiÞcial water containers. So far, no study has addressed the role that density dependence and weather ßuctuations could have played in the abundance of this nonvector mosquito. A year-long study was conducted on the population dynamics of this mosquito using oviposition traps in Okinawa, Japan. Time series analysis and the Ricker population model were used to analyze the association between mosquito density and population growth and ßuctuations in relative humidity, temperature, and rainfall. Our results suggest that Ur. novobscura ryukyuana has stable denso-dependent dynamics, which are autonomous from weather ßuctuations. Our results were opposite to patterns observed in other subtropical mosquito species, whose population dynamics might be partially driven by weather ßuctuations, thus highlighting the diversity of responses that mosquitoes can have to changing environments.
