“…16 These patterns were not well correlated with the season or temperature. We do not have a better explanation than what Porter and Tschinkel 17 and Vogt et al 18 pointed out, that some unexplained variation in foraging activity during season often occurs. Therefore, temperature and season may not be used alone to predict optimal foraging.…”

Abstract:This study provides empirical evidence that disturbing mound immediately before application, as opposed to label recommendation, did not reduce foraging activity of the red imported fi re ant, Solenopsis invicta Buren, except for about 10-min delay in foraging. Despite the delayed foraging, there was no signifi cant difference in the amount of baits foraged between disturbed and undisturbed colonies. Eventually, Ͼ96% of the baits were foraged, with the maximum removal occurred by 2 and 3 h, respectively, in summer and spring trial. The fastest and great amount of bait removal 1 h post-treatment occurred to baits placed on mound, followed by 0.18-0.3-m from mound base, and the slowest 1.08-1.2-m from mound base. All treatment gave 100% control 1 mo later, regardless of the season, without colony relocation or new colony invasion in the test plots. Keywords: solenopsis invicta, individual mound treatment, bait application, season effectThe red imported fi re ant, Solenopsis invicta (Buren) (Hymenoptera: Formicidae), is a major constant pest in agricultural and urban sectors in the southeastern United State 1,2 and has substantial impact on humans, wildlife, and agriculture. 3,4 One approach to manage fi re ants is the use of toxic baits in which a toxicant, a food attractant, and a carrier are combined into granular bait and applied broadcast or to individual mounds. Baits are often promoted to the public as the most practical, economic and effective component in integrated fi re ant management programs because they allow the dissemination of the active ingredients to an entire colony via social feeding behavior. 5,6 Registration labels on commercial fi re ant baits generally suggest, with no research-based data, not to disturb fi re ant mound and to place baits on the ground in a circle Ͻ1.2 m around the mound but not directly on mound. Despite the labels, homeowners and some pest control professionals still claim that applying bait on and around pre-disturbed mounds via foot-kicking or racking or shoveling provides better control. Up to date, research on baits has focused on what makes the best active ingredients 5,7,[8][9][10][11][12][13] or bait formulations. 14,15 The only research on the impact of not following label suggestions reported no signifi cant effect on mound disturbance concerning the total amount of bait removed by fi re ants. The research was conducted in winter season when foraging activity was low. 16 The resulting bait consumption was Ͻ44% regardless of whether the colonies were disturbed. Additionally, that study did not evaluate treatment effi cacy.Fire ants are known for seasonally changing foraging activity 17,18 and bait preference. 19 We conducted this study in spring and summer seasons of the year 2008. Our objectives were to determine: 1) whether disturbing mound before bait application reduces fi re ant foraging activity; 2) whether bait placed on mound is less accessible, as opposed to that around the mound; 3) whether mound disturbance will reduce treatment effi cacy; and ...

“…Temperature can regulate ant colony foraging activity (Vogt et al 2003), oviposition rates (e.g., Newell & Barber 1913 cited in Vega & Rust 2001), development of brood (Porter 1988), nest site selection (chen et al 2002), and extremes of temperature can kill adults or whole colonies (korzukhin et al 2001). …”

Relative risk of invasive ants (Hymenoptera: Formicidae) establishing in New Zealand

Human-assisted spread of species poses a major challenge to border security agencies. Ideally, limited resources need to be targeted at species posing the most risk. Climate matching is an important component of assessing risk but often little or no biological information is available to enable detailed modelling. To assess if distribution records alone provide useful establishment predictions we compare the climate in New Zealand and its outlying islands to that found in the current native and introduced ranges of 12 tramp ant species, three of which are already established in New Zealand, using the climate module of BIOSECURE, a risk assessment tool. Eleven species showed a similar general pattern, with mean annual temperature being the climatic variable with the least overlap between the estimated realised niche and the predicted New Zealand niche. The twelfth species, of temperate origin, is less restricted by temperature, but much of New Zealand may have too high a rainfall. The present and future threats posed by tramp ants are discussed in relation to climate limitations.

“…Ground nesting insects like many wasp, bee, and ant species probably depend more on soil temperature than on air temperature with regard to nest-site selection, daily activity patterns, as well as foraging success and sex allocation (e.g., Cameron et al, 1996;Crist and Williams, 1999;Potts and Willmer, 1997;Strohm and Linsenmair, 1998;Vogt et al, 2003;Wuellner, 1999).…”

The influence of soil temperature on the nesting cycle of the halictid bee Lasioglossum malachurum

et al. 2006

Abstract. The physiology and behavior of ectothermic organisms is strongly influenced by temperature. For ground nesting species like the primitively eusocial halictid bee, Lasioglossum malachurum, soil temperature might influence the life cycle as well as the complexity of the social group since the number of broods that can be fitted into the flight season might increase with increasing temperature. Our study population of L. malachurum at Wuerzburg exhibits a remarkable variability with respect to the number of broods and the pattern of sexual production. Broods are separated by activity pauses during which the larvae develop. In this study we investigate the influence of soil temperature on the pattern of nesting activity (duration of broods and pauses) and on the number of broods in L. malachurum. We observed a total of 1138 nests in 13 aggregations near Wuerzburg. As expected, soil temperature shortened the duration of the pauses, resulting in an overall shortening of the nesting cycle. This is most probably due to a physiological effect of soil temperature on the development of the larvae. With regard to the nesting strategies, we hypothesized that a shortening of the nesting cycle within the limited flight season should enhance the success of a strategy with more worker broods. In fact, patches with higher soil temperature showed more broods. However, this effect was rather weak, suggesting that other factors might have a stronger impact on the variability in nesting strategy within our study population of L. malachurum.
