Introductions for Biological Control in Hawaii: 1979 and 1980
Vol. 24, No. 1, September 15, 1982 109 Introductions for Biological Control in Hawaii: 1979 and 1980 PY. LAI, G.Y. FUNASAKI, S Y. HIGA1 The Plant Pest Control Branch (formerly Entomology Branch) of the Hawaii Department of Agriculture has maintained a beneficial organism introduction program for many years. This paper provides notes on the status of some pests and their purposely introduced natural enemies and a list of insects introduced and released for biological control during 1979 and 1980 (Table 1). All benefi cial introductions are thoroughly screened and studied in a quarantine facility and must go through a clearance process prior to being released. WEED PEST CONTROL Ageratina riparia (Regel) K. & R. (Hamakua pamakani) Three organisms contributing to the control of Hamakua pamakani are the stem galling tephritid, Procecidochares alani Steyskal, the leaf defoliating ptero- phorid, Oidaematophorus sp., and the leaf spotting fungus, Cercosporella sp. (introduced by Dr. E.E. Trujillo, Univeristy of Hawaii Plant Pathologist). P. alani was initially released on Hawaii Island in 1974, Oidaematophorus sp. in 1973 andC. sp.in 1975. The combined activities of these purposely introduced beneficial organisms have contributed by severely reducing thickets of Hamakua pamakani on the island of Hawaii. Desirable forage grasses have replaced pamakani in 16,000 to 20,000 ha of pasture lands. Many of these previously heavily infested lands have been restored to productive use. Salsola pestifer A. Nelson (Russian thistle) Through the cooperation of the USDA Biological Control of Weeds Labora tory, Albany, California, two beneficial coleophorids, Coleophora parthenica Meyrick and C. klimeschiella Toll, were introduced to aid in the control of Rus sian thistle, a noxious weed that infests about 320 ha of rangelands on Hawaii. -
Induced Resistance Mitigates the Effect of Plant Neighbors on Susceptibility to Herbivores
Induced resistance mitigates the effect of plant neighbors on susceptibility to herbivores KATHERINE D. HOLMES AND ANURAG A. AGRAWAL Department of Ecology and Evolutionary Biology, Cornell University, Ithaca, New York 14853 USA Citation: Holmes, K. D., and A. A. Agrawal. 2021. Induced resistance mitigates the effect of plant neighbors on susceptibility to herbivores. Ecosphere 12(1):e03334. 10.1002/ecs2.3334 Abstract. At small spatial scales, attraction or deterrence of herbivores by plant neighbors can alter the susceptibility of plants to damage (i.e., associational effects). Given the patchy nature of plants and insect herbivory, we hypothesized that induced resistance may play an important role in mitigating such spatial variability. To test this notion, we first documented neighbor effects between two closely related and co-oc- curring plant species in natural populations, and second, we measured how these effects changed after inducing plant resistance in a common garden. In wet fields and marshes of Northeastern North America, boneset (Eupatorium perfoliatum) is the primary host for the herbivorous beetle Ophraella notata. Across two years of surveys at multiple sites, we found that Joe Pye weed (Eutrochium maculatum) was a secondary host to O. notata and was more likely to receive beetle eggs when it grew near boneset, constituting a nega- tive neighbor effect (associational susceptibility) for Joe Pye weed. Reciprocally, there were trends of reduced susceptibility for boneset when it grew near Joe Pye weed (a positive neighbor effect), but this pat- tern was less consistent over space and time. In the common garden, we manipulated patches, each with a center (focal) and surrounding (neighbor) plants, with focal plants of each species either induced by the plant hormone jasmonic acid or left as controls. -

Differential Susceptibility of Russian Thistle Accessions to Colletotrichum Gloeosporioides

Box 102, Budapest 1525, Hungary c USDA-ARS-EIDP, 9611 South Riverbend Ave., Parlier, CA 93648, USA Received 16 May 2003; accepted 1 December 2003. Available online 30 December 2003. Abstract Molecular information suggests that Russian thistle (Salsola tragus L.) in the US may consist of more than one genetic entity. This genetic variation needs to be taken into account when developing agents for biological control of this important weed. Preliminary evidence suggests that there are differences in susceptibility of Salsola sp. to infection by fungal pathogens. In the present study, an isolate of Colletotrichum gloeosporioides, a pathogen of Russian thistle collected in Hungary was tested for its ability to infect and damage California accessions of S. tragus (referred to as Type A) and the related S. tragus, Type B. The minimum dew period and temperature required for infection of S. tragus with C. gloeosporioides was determined to be 12–16 h and 25 °C. Both Type A and Type B were susceptible, but C. gloeosporioides caused greater damage and reductions in biomass of Type A than of Type B. Fresh weights of Type A and Type B were reduced from controls by 60 and 9%, respectively, after inoculations with C. gloeosporioides. Results from this study illustrate the importance of understanding target plant taxonomy in biological control evaluations. -

Responses of Insect Herbivores and Herbivory to Habitat Fragmentation: a Hierarchical Meta-Analysis
Ecology Letters, (2017) 20: 264–272 doi: 10.1111/ele.12723 REVIEW AND SYNTHESIS Responses of insect herbivores and herbivory to habitat fragmentation: a hierarchical meta-analysis Abstract Marıa Rosa Rossetti,1,* Teja Loss and fragmentation of natural habitats can lead to alterations of plant–animal interactions Tscharntke,2 Ramiro Aguilar3,4 and and ecosystems functioning. Insect herbivory, an important antagonistic interaction is expected to Peter Batary 2 be influenced by habitat fragmentation through direct negative effects on herbivore community richness and indirect positive effects due to losses of natural enemies. Plant community changes with habitat fragmentation added to the indirect effects but with little predictable impact. Here, we evaluated habitat fragmentation effects on both herbivory and herbivore diversity, using novel hierarchical meta-analyses. Across 89 studies, we found a negative effect of habitat fragmentation on abundance and species richness of herbivores, but only a non-significant trend on herbivory. Reduced area and increased isolation of remaining fragments yielded the strongest effect on abun- dance and species richness, while specialist herbivores were the most vulnerable to habitat frag- mentation. These fragmentation effects were more pronounced in studies with large spatial extent. The strong reduction in herbivore diversity, but not herbivory, indicates how important common generalist species can be in maintaining herbivory as a major ecosystem process. Keywords Body size, effect size, feeding type, fragment area, generalist herbivores, insect herbivory, isola- tion, spatial extent, species richness. Ecology Letters (2017) 20: 264–272 may trigger alterations in plant community structure and an INTRODUCTION array of ecosystem functions (Maguire et al. 2015).
