Stevens ABSTRACT POPULATION RESPONSES OF A GENERALIST INSECT PREDATOR AND ITS PREY TO PATCH CHARACTERISTICS IN FORAGE CROPS by David Jon Stasek There is a large body of literature documenting the effect of habitat features on populations of single species, but there are fewer studies documenting the effects of patch characteristics on community and ecosystem processes. Specifically, there are few studies that document the effect of dispersal among habitat patches on species interactions. Using an experimental field of forage crops, I assessed the population response of a generalist predatory insect, the damsel bug ( Nabis spp.), to prey density and the patch characteristics of size, matrix type, and habitat fragmentation. I then determined the functional response and preference of the damsel bug to two common leafhopper species in the forage-crop system: the constricted leafhopper ( Agallia constricta ) and the clover leafhopper ( Ceratagallia agricola ). Finally, I studied how dispersal among habitat patches and leafhopper and damsel bug density affected the survival of A. constricta using connected experimental mesocosms. In the experimental field, damsel bugs had higher abundances in large patches and patches surrounded by an orchard-grass matrix. Both damsel bug nymphs and adults aggregated in patches with high densities of constricted leafhoppers and aphids. There was no effect of habitat fragmentation. In functional response experiments, the damsel bug displayed a Type I functional response to both species of leafhoppers and showed a preference for A. constricta . In experimental mesocosms, there was no difference in the survival probabilities of leafhoppers in any treatment when isolation and conspecific density were varied. Damsel bug density and dispersal did affect the survival probability of leafhoppers with leafhoppers having lower survival rates in patches that were not isolated from one another. This study is one of the first experimental tests of varying dispersal to assess the survival probability of species within a metacommunity, as well as assessing the effects of patch characteristics on interspecific interactions. Results from this research also indicate that the damsel bug may be a candidate to help control A. constricta in agroecosystems.

As a result of habitat loss, animals must often move among local habitat patches to find food resources (Hanski et al. 1994, Kuussaari et al. 1996), mating opportunities (Kuussaari et al. 1996, Šálek and Marhoul 2008), or over-wintering sites (Thies and Tscharntke 1999, Tscharntke et al. 2002), thus linking population dynamics among patches. There is now a large body of literature documenting how the alteration of patch characteristics affects population dynamics and species abundance. Characteristics such as habitat patch size (Gustafson and Gardner 1996, Moilanen and Hanski 1998), isolation (Moilanen and Hanski 1998), shape (Diamond 1975, Stamps et al. 1987), arrangement (Holyoak 2000), and quality (Kuussaari et al. 1996, Thomas et al. 2001) all affect population dynamics of species in local habitat patches in fragmented landscapes. In addition to patch characteristics, the type of edge habitat surrounding a patch (Stamps et al. 1987, Schtickzelle and Baguette 2003), as well as the intervening matrix habitat (Ricketts 2001, Stasek et al. 2008), influence dispersal rates among suitable habitat patches.

Medler INTRODUCTION HIS bulletin attempts to present as accurate and complete a T guide to the leafhoppers of Minnesota as possible within the limits of the material available for study. It is realized that cer- tain groups could not be treated completely because of the lack of available material. Nevertheless, it is hoped that in its present form this treatise will serve as a convenient and useful manual for the systematic and economic worker concerned with the forms of the upper Mississippi Valley. In all cases a reference to the original description of the species and genus is given. Keys are included for the separation of species, genera, and supergeneric groups. In addition to the keys a brief diagnostic description of the important characters of each species is given. Extended descriptions or long lists of references have been omitted since citations to this literature are available from other sources if ac- tually needed (Van Duzee, 1917).

    Life: The Excitement of Biology 4(1) 32 Review of the West Indian Arachnocoris Scott, 1881 (Hemiptera: Nabidae), with Descriptions of Two New Species, and a Catalog of the Species1 Javier E. Mercado2, Jorge A. Santiago-Blay3, and Michael D. Webb4 Abstract: We review the West Indian species of Arachnocoris, a genus of spider-web dwelling kleptoparasitic nabids. We recognize five species: A. berytoides Uhler from Grenada, A. darlingtoni n. sp. from Hispaniola, A. karukerae Lopez-Moncet from Guadeloupe, A. portoricensis n. sp. from Puerto Rico, and A. trinitatis Bergroth from Trinidad. West Indian Arachnocoris antennal and profemoral color banding patterns are useful diagnostic characters and may have evolved to mimic their spider hosts, which are often island endemic spiders in the family Pholcidae. We provide a simplified and illustrated key to the species based on external characters. A catalog for the 16 recognized species of Arachnocoris is presented. Keywords: Hemiptera, Nabidae, Arachnocoris, new species, Neotropical, West Indies Introduction The Nabidae are a relatively small family in the insect order Hemiptera with approximately 20-30 genera and 400-500 described species (Henry 2009, Faúndez and Carvajal 2014). All described species are terrestrial predators. Some species are considered beneficial to humans as these help control populations of agricultural pests. Several species of Nabis have been reported as biting humans (Faúndez 2015). Within the Nabidae Arachnocoris is one of two genera in the tribe Arachnocorini. The arachnophilic genus5 Arachnocoris Scott is a small and little-known group of specialized kleptoparasitic nabids that spend their life- stages living in a relatively treacherous habitat, namely a spider’s web, particularly non-sticky portions of it (Henry 1999; Mercado-Santiago-Blay 2015; Figure 1, this paper).

    ENTOMOPHAGA 35 (3), 1990, 449-458 RESPONSE OF NABIS ROSEIPENNIS [HETEROPTERA : NABIDAE] TO LARVAE OF MEXICAN BEAN BEETLE, EPILACHNA VARIVESTIS [COL. : COCCINELLIDAE] R. N. WIEDENMANN & R. J. O'NEIL Department of Entomology, Purdue University, West Lafayette, in 47907, USA Laboratory studies were done to measure predation by adult.damsel bugs, Nabis roseipennis Reuter [Heteroptera : Nabidae], on 3 rd instar larvae of Mexican bean beetle (MBB), Epilachna varivestis Mulsant [Coleoptera : Coccinellidae], and to measure longevity and body weight of the nabids. In the I st experiment, field-collected nabids were isolated for 24 h in 9 cm Petri dishes with lima bean foliage (Phaseolus lunatus L.) and were assigned to one of 3 prey treatments : either 4 3ra-instar MBB larvae, 4 3~a-instar larvae of boll weevil (BW), Anthonomus grandis Boheman [Coleoptera : Curculionidae], or 2 larvae of each species. No MBB larvae were attacked in either the MBB treatment or 2-species treatment. In contrast, BW larvae were attacked in both BW and 2-species treatments. Signifi- cantly more BW larvae were attacked in the BW treatment than in the 2-species treatment, and both were greater than the number of MBB larvae attacked. Nabids that did not attack prey lost weight during the 24 h, whereas those that attacked prey gained weight. In the 2 nd experiment, nabids that had attacked prey were isolated with lima foliage, and nabids that had not attacked prey were kept with MBB and lima foliage until an attack or death. In no instances were MBB attacked. Longevity and the pattern of weight loss did not differ between nabids that did or did not attack prey.
