BIOLOGY and ECOLOGY of TWO PREDATORS, Geocoris Pallens Stàl and G MT& BIOLOGY AND ECOLOGY OF TWO PREDATORS, Geocoris pallens Stàl and G. bullatus (Say) Teclmical Bulletin No. 1446 0^ Agricultural Research Service UNITED STATES DEPARTMENT OF AGRICULTURE ABSTRACT Biology and ecology of Geocoris pallens and G. bullatus, two omnivorous preda- tors, were studied. Laboratory-rearing and interbreeding tests were conducted to differentiate the life stages of both species. Eggs of Geocoris hatched at 21° to 41° C, and egg developmental rate varied with temperature and also with time of adult collection. Combination of sunflower seeds, insects, and green plant food was the best diet for the quickest developmental rate, highest egg production, and the greatest survival rate. Sunflower seed when placed in the field concentrated Geocoris and increased oviposition. Alfalfa as interplants in a mixed-culture ex- periment served as a breeding and reservoir site for Geocoris. Geocoris was also the most abundant predator in the predator complex in the mixed-culture experi- ment. Daily high temperatures above 24° appear to be correlated with the increase in Geocoris flight. In the seasonal-life-history studies on alfalfa G. bullatus over- wintered in the adult and egg stage and had at least three generations per year, but G. pallens overwintered as adults and had at least two generations per year. Both species decline in September on cultivated crops, but G. bullatus is found in great abundance in orchardgrass in the fall. ACKNOWLEDGMENT We wish to thank B. J. Landis, R. L. Wallis, and H. R.

Big-eyed bugs (Geocoris spp. Fallen,´ Hemiptera: Lygaeidae) are ubiquitous, omnivorous insect predators whose plant feeding behavior raises the question of whether they benefit or harm plants. However, several studies have investigated both the potential of Geocoris spp. to serve as biological control agents in agriculture and their importance as agents of plant indirect defense in nature. These studies have demonstrated that Geocoris spp. effectively reduce herbivore populations and increase plant yield. Previous work has also indicated that Geocoris spp. respond to visual and olfactory cues when foraging and choosing their prey and that associative learning of prey and plant cues informs their foraging strategies. For these reasons, Geocoris spp. have become models for the study of tritrophic plant-herbivore-predator interactions.

  • Insecticideinduced Hormesis and Arthropod Pest Management
    Review Received: 31 August 2013 Revised: 7 October 2013 Accepted article published: 23 October 2013 Published online in Wiley Online Library: 2 December 2013 (wileyonlinelibrary.com) DOI 10.1002/ps.3669 Insecticide-induced hormesis and arthropod pest management Raul Narciso C Guedesa∗ and G Christopher Cutlerb Abstract Ecological backlashes such as insecticide resistance, resurgence and secondary pest outbreaks are frequent problems associated with insecticide use against arthropod pest species. The last two have been particularly important in sparking interest in the phenomenon of insecticide-induced hormesis within entomology and acarology. Hormesis describes a biphasic dose–response relationship that is characterized by a reversal of response between low and high doses of a stressor (e.g. insecticides). Although the concept of insecticide-induced hormesis often does not receive sufficient attention, or has been subject to semantic confusion, it has been reported in many arthropod pest species and natural enemies, and has been linked to pest outbreaks and potential problems with insecticide resistance. The study of hormesis remains largely neglected in entomology and acarology. Here, we examined the concept of insecticide-induced hormesis in arthropods, its functional basis and potential fitness consequences, and its importance in arthropod pest management and other areas. c 2013 Society of Chemical Industry Keywords: biphasic concentration–response; hormoligosis; insecticidal stress; insecticide ecotoxicology; pesticide-mediated homeostatic regulation; sublethal effects 1 HORMESIS: ANCIENT ADAGES, OLD LAWS group recognized the general nature of the phenomenon in a suc- AND CURRENT THEORY cession of meta-analyses.9–13 They suggested that the hormetic Friedrich Nietzsche in his Twilight of the Idols (1888) expressed dose–response model is more common in toxicology than the threshold model (Fig.

Shared senior authors and corresponding authors. y Received: 13 November 2019; Accepted: 10 December 2019; Published: 15 December 2019 Abstract: Sustainable pest control requires a systems approach, based on a thorough ecological understanding of an agro-ecosystem. Such fundamental understanding provides a basis for developing strategies to manipulate the pest’s behaviour, distribution, and population dynamics, to be employed for crop protection. This review focuses on the fundamental knowledge required for the development of an effective push-pull approach. Push-pull is a strategy to repel a pest from a crop, while attracting it toward an external location. It often relies on infochemicals (e.g., pheromones or allelochemicals) that are relevant in the ecology of the pest insect and can be exploited as lure or repellent. Importantly, responsiveness of insects to infochemicals is dependent on both the insect’s internal physiological state and external environmental conditions. This context-dependency reflects the integration of cues from different sensory modalities, the effect of mating and/or feeding status, as well as diurnal or seasonal rhythms. Furthermore, when the costs of responding to an infochemical outweigh the benefits, resistance can rapidly evolve.

Broadway Rd., Phoenix, AZ 85040, USA; 2Department of Entomology, University of Arizona, Tucson, AZ 85721, USA Accepted: February 28, 1989 Key words: Geocoris, Bemisia, predator, handling time Abstract Geocoris punctipes (Say), a predaceous lygaeid not previously documented as a whitefly predator, was tested in the laboratory as a natural enemy of the sweet potato whitefly, Bemisia tabaci (Genn.). Its stalking behavior with whiteflies as prey was similar to that observed with aphids. A previously unob- served behavior was noted that involves the predators using salivary secretions to fasten the wings of prey to various surfaces, allowing labial probing and feeding. Prey consumption as a function of prey number appeared to follow the pattern of the Holling type II functional response. Handling time per prey item ranged from about 180 to 240 seconds. No changes were observed in handling time devoted to earlier versus later catches. Nutritional quality of whiteflies was measured using crude protein, lipids and carbohydrates as criteria. Performance, in terms of predator behavior, total daily handling time, func- tional response, energy budget and nutritional quality all support the hypothesis that G. punctipes is a promising candidate for biological control of sweet potato whiteflies.
