Several success cases of biological control can be found in the tropics around the world. The classical biological control has been applied with greater emphasis in Australia and Latin America, with many success cases of exotic natural enemies’ introduction for the control of exotic pests. Augmentative biocontrol is used in extensive areas in Latin America, especially in the cultures of sugar cane, coffee, and soybeans.

  • Discovering the True Chrysoperla Carnea (Insecta: Neuroptera: Chrysopidae) Using Song Analysis, Morphology, and Ecology
    SYSTEMATICS Discovering the True Chrysoperla carnea (Insecta: Neuroptera: Chrysopidae) Using Song Analysis, Morphology, and Ecology 1 2 3 4 CHARLES S. HENRY, STEPHEN J. BROOKS, PETER DUELLI, AND JAMES B. JOHNSON Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT 06269Ð3043 Ann. Entomol. Soc. Am. 95(2): 172Ð191 (2002) ABSTRACT What was once considered a single Holarctic species of green lacewing, Chrysoperla carnea (Stephens), has recently been shown to be a complex of many cryptic, sibling species, the carnea species group, whose members are reproductively isolated by their substrate-borne vibrational songs. Because species in the complex are diagnosed by their song phenotypes and not by morphology, the current systematic status of the type species has become a problem. Here, we attempt to determine which song species corresponds to StephensÕ 1835 concept of C. carnea, originally based on a small series of specimens collected in or near London and currently housed in The Natural History Museum. With six European members of the complex from which to choose, we narrow the Þeld to just three that have been collected in England: C. lucasina (Lacroix), Cc2 Ôslow-motorboatÕ, and Cc4 ÔmotorboatÕ. Ecophysiology eliminates C. lucasina, because that species remains green during adult winter diapause, while Cc2 and Cc4 share with StephensÕ type a change to brownish or reddish color in winter. We then describe the songs, ecology, adult morphology, and larval morphology of Cc2 and Cc4, making statistical comparisons between the two species. Results strongly reinforce the conclusion that Cc2 and Cc4 deserve separate species status. In particular, adult morphology displays several subtle but useful differences between the species, including the shape of the basal dilation of the metatarsal claw and the genital ÔlipÕ and ÔchinÕ of the male abdomen, color and coarseness of the sternal setae at the tip of the abdomen and on the genital lip, and pigment distribution on the stipes of the maxilla.

    JOURNAL OF PLANT PROTECTION RESEARCH Vol. 52, No. 1 (2012) FLIGHT DYNAMICS OF OSTRINIA NUBILALIS HBN. (LEP., CRAMBIDAE) BASED ON THE LIGHT AND PHEROMONE TRAP CATCHES IN NIENADÓWKA (SOUTH-EASTERN POLAND) IN 2006–2008 Paweł K. Bereś* Institute of Plant Protection – National Research Institute Regional Experimental Station Langiewicza 28, 35-101 Rzeszów, Poland Received: September 29, 2011 Accepted: October 30, 2011 Abstract: The experiment was conducted in the 2006–2008 time period, in Nienadówka near Rzeszów, Poland (50°11’ N, 22°06’ E). The high suitability of light traps for the monitoring of Ostrinia nubilalis Hbn. moth flights on maize fields was shown. These light traps were compared to the pheromone types of traps; the “delta” model, and the “funnel” with a pheromone dispenser containing Z–11–tetradecenyl acetate (series ONC036A and ONC048A/107). In the light trap, the first moths were found in the second decade or third decade of June. The population peak was in the first decade or second decade of July, and the end of the flight in August. In September 2007 and 2008, single O. nubilalis moths collected in the light trap indicated the presence of a small second pest generation. The first male moths were captured in the pheromone traps in the third decade of June or the first decade of July, with a slightly marked population peak in the first or second decade of July. The moth flight ended in the last decade of July. The first egg clusters of O. nubilalis were usually recorded 4–7 days after the first moths were found in the light trap.

Results of studies on prey suitability for generalist predators are important for efficient mass rearing and implementing Integrated Pest Management Programmes (IPM). The green lacewing, Chrysoperla sinica (Tjeder), is a polyphagous natural enemy attacking several pests on various crops in China. We investigated the effect of feeding it different species of prey on its pre- imaginal development, survival, adult longevity and fecundity under laboratory conditions. The prey species tested were nymphs of Aphis glycines Matsumura, cotton aphid Aphis gossypii Glover, peach aphid Myzus persicae Sulzer, corn aphid Rhopalosiphum maidis Fitch and cowpea aphid Aphis craccivora Koch, and eggs of the rice grain moth, Corcyra cephalonica Stainin. None of these species of prey affected the pre-imaginal survival or percentage survival of the eggs of the predator. However, eggs of C. cepha- lonica and nymphs of M. persicae and A. glycines were the best of the prey species tested, in that when fed on these species the pre- imaginal developmental period of C.
