Spaulding, Gypsy Moth Program Coordinator Emergency and Domestic Programs 4700 River Road, Unit 137 Riverdale, MD 20737 301–851–2184 [email protected] Abstract: The USDA Forest Service and Animal and Plant Health Inspection Service are proposing an addition to the gypsy moth management program that was described in the 1995 Environmental Impact Statement—Gypsy Moth Management in the United States: a cooperative approach—and chosen in the 1996 Record of Decision. The agencies are proposing these new treatment options: adding the insecticide tebufenozide, or adding the insecticide tebufenozide and other new treatment(s) that may become available in the future to manage gypsy moths, provided that the other treatment(s) pose(s) no greater risk to human health and nontarget organisms than are disclosed in this Final Supplemental Environmental Impact Statement for the currently approved treatments and tebufenozide. The addition of tebufenozide or other new treatment(s) to the list of approved treatment options does not change any program or administrative requirements identified in the 1995 EIS. Those requirements include any consultations required and the need to conduct site-specific environmental analyses in accordance with the National Environmental Policy Act and agency regulations.

A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains,

The densities established were converted to weight of prey offered: 13.4 mg (one larva), 33.3 mg (three larvae), 54.3 mg (five larvae), 81.8 mg (seven larvae), and 110.34 mg (nine larvae). The quantity of food consumed by P. nigrispinus increased with the prey density. The density of preys did not affect the time spent by the predator to ingest the food. The quantity of food extracted per minute was always higher in smaller densities and lower in higher densities. Males mean body weight did not differ statistically between the treatments tested, and weight gain was smaller in the first two densities tested. Relative consumption rates increased with the quantity of larvae offered. P. nigrispinus males might change its predatory behavior as a function of the quantity of prey available.

Serrano 2,3, Paul J. Johnson4 & Jocelyn G. Millar2 Species-specifc behavior-modifying chemicals have been used for more than 50 years for monitoring and management of insect pests of agriculture and human health. Elaterid beetle larvae are among insect pests in soil that are increasingly problematic, in part due to the lack of efective management strategies. However, little is known about the insect-produced chemicals that mediate the reproductive behavior of these pests. We used chemical and behavioral studies to identify, synthesize, and feld test the sex attractant pheromone of adults of Melanotus communis, commonly called the corn wireworm, the larvae of which are economically important pests of U.S. crops. Our results indicated that a single female-produced chemical, 13-tetradecenyl acetate, was strongly attractive to conspecifc male beetles, and did not appear to attract other species. In feld evaluations, male M. communis exhibited a dose-dependent response to this compound. In a trial comparing diferent slow-release dispensers, a small rubber septum impregnated with the chemical was as efective as and easier to use than a plastic bag dispenser. Given that the sex attractant of this insect consists of a single compound that can be readily synthesized, its development for monitoring and management of the corn wireworm may be economically feasible. Te click beetles (Coleoptera: Elateridae) comprise a large and diverse family of insects, with > 12,000 described species worldwide (P.J.

    DEVELOPMENT AND SURVIVAL OF PODZSUS MACULZVENTRZS (SAY) AND PODZSUS SAGZTTA (FAB.) (HETEROPTERA: PENTATOMIDAE) AT VARIOUS CONSTANT TEMPERATURES P. DE CLERCQand D. DEGHEELE Laboratory of Agrozoology, Faculty of Agricultural Sciences, University of Gent, Coupure Links 653, B-9000 Gent, Belgium Abstract Can. Ent. 124: 125-133 (1992) Development and survival of the predatory pentatomids Podisus rnaculiventris (Say) and Podisus sagitta (Fab.) were studied at six constant temperatures ranging from 19 to 35OC. Time required for development from egg to adult ranged from 48.9 days (19°C) to 18.9 days (30°C)for P. rnaculiventris and from 5 1.9 days (1 9°C)to 16.9 days (33°C) for P. sagitta. At 33"C, eggs of P. rnaculiventris did not hatch and development of nymphs that had emerged at 23°C was retarded; none of the first-instar nymphs incu- bated at 35OC survived the next moult. A constant temperature of 35°C was fatal to P. sagitta eggs and extended the developmental period of nymphs from 23°C. Egg hatch ranged from 47% (19°C)to 57% (27°C)for P. rnaculiventris and from 54% (33°C) to 71% (27°C)for P. sagitta. Nymphal survival was high at moderate temperatures, with 63-78% and 65-82% of the first-instar nymphs of the respective species reaching adulthood. Mortality during the nymphal stage was significantly increased at high tem- peratures, but was considerably lower for P. sagitta than for P. rnaculiventris. Lower threshold temperatures for egg and nymphal development were estimated to be 10.7 and 1 1.7"Cfor P.

Pre-conditioning, insect developmental stage and environmental conditions should be considered when selecting storage conditions in order to obtain the highest performance after storage. We evaluated the influence of nutrient quality on the response of eggs, nymphs and adults of Podisus maculiventris when exposed to two temperatures most likely to be used for long-term storage. Natural prey-fed insects were compared to artificial diet-fed insects. The results of our study showed that eggs survived storage at 10 °C better than 4 °C, and that eggs from diet-fed insects survived storage at 10 °C significantly better than eggs from prey-fed insects. Nymphal survival of cold storage treatment was slightly higher than for eggs, with a similar pattern of response to temperature, nutrient quality and time of storage. However, of the three developmental stages tested, the best survival was obtained with adults. Similar to eggs and nymphs, adults survival was higher at 10 °C. However, different from eggs and nymphs was that the prey-fed adults survived better than diet-fed adults.

  • Rapid Pest Risk Analysis (PRA) for Platynota Flavedana Platynota

    Rapid Pest Risk Analysis (PRA) for Platynota Flavedana Platynota

    Rapid Pest Risk Analysis (PRA) for Platynota flavedana Platynota idaeusalis Platynota rostrana STAGE 1: INITIATION 1. What is the name of the pest? Three species are considered in this PRA because there are considerable similarities in their biology and all three are only present in the new world. All are tortricid moths (Lepidoptera, Tortricidae). Platynota flavedana Clemens, variegated leafroller (VLR) Platynota idaeusalis (Walker), tufted apple bud moth (TBAM) Platynota rostrana (Walker), orange leafroller Brown et al. (2011b) have suggested that P. rostrana may be a species complex, but the precise status has not been confirmed and it is treated as one species here. There are no known taxonomic issues with either P. flavedana or P. idaeusalis. However, many species in Platynota are very similar, both as larvae and adults, and species identification can be problematic, particularly where the precise geographic origin of the specimen is unclear or the adult is in a worn condition. 2. What initiated this rapid PRA? Platynota sp. larvae, believed to be either P. rostrana or P. flavedana, were detected on Annona muricata (custard apples) imported from Jamaica in August 2011. Although the consignment was not held in this case, it was anticipated that statutory action would be recommended following any future finds. As a result, the three species of Platynota included in this PRA (as well as a fourth species, P. stultana, which is covered in a separate PRA) were included in Phase I of the UK Plant Health Risk Register in 2013, and all were identified as a priority for PRA. 3. What is the PRA area? The PRA area is the United Kingdom of Great Britain and Northern Ireland.

    Hervibors Hosts Influence on Insecticide Resistance: a Review

    Rev. Fac. Agron. (LUZ).1999,16: 127-140 Docurnent: Hervibors hosts influence on insecticide resistance: a review Documento: La influencia del hospedero en la resistencia de hervíboros a insecticidas: una revisión Abstract Resistance is a worldwide problem, which if ignored or improperly niana- ged, will significantly reduce worldwide agricultura1 production and public health. Resistance is influenced by genetic factors but also there is an environmental effect, which in the case of phytofagas diseases is partially represented by the chemicals found in the host plants. Species with an evolutionary history of feeding on heavily chemically defended plant structures shoiild have elwated levels of enzyrnes that detoxify defensive chemicals, and therefore an enhrinced ability to evolve resistance to synthetic toxins. The role of host plant cheniistry on the expression and evolution of pesticide resistance is reviewed from the per- spective of understanding the non-genetic factors influencing pesticide resist arice. This perspective is important since environmental factors may have re1ai;ively important effects influencing the activity of detoxification enzymes in anirnals, and hence, susceptibility to xenobiotics. Research on non-genetic factors influ- encing pesticide resistance must be undertaken if we are to iiicrease our confi- dence in proposed management strategies. Key words :detoxification enzymes, pesticide resistance, non-genetic factors, susceptibility to allelochemicals. Resumen La resistencia de hervi%oros a insecticidas es un problema a nivel mundial, que si es ignorado o manejado inadecuadamente, reduciría significativame-ntela producción agrícola mundial y la salud pública. La resistencia está influenciada por factores genéticos pero también existe un efecto del medio ambiente, que en el caso de las plagas fitófagas está en parte representado por sustancias químicas ~écibidoel 19-12-1996 Aceptado el 24-09-1997 1.
