Effect of Different Host Plants of Normal Wheat Aphid (Sitobion Avenae) on the Feeding and Longevity of Green Lacewing (Chrysoperla Carnea)
2011 International Conference on Asia Agriculture and Animal IPCBEE vol.13 (2011) © (2011)IACSIT Press, Singapoore Effect of different host plants of normal wheat aphid (Sitobion avenae) on the feeding and longevity of green lacewing (Chrysoperla carnea) Shahram Hesami 1, Sara Farahi 1 and Mehdi Gheibi 1 1 Department of Plant Protection, College of Agricultural Sciences, Shiraz branch, Islamic Azad University, Shiraz, Iran Abstract. The role of two different hosts of normal wheat aphid (Sitobion avenae) on feeding and longevity of larvae of green lacewing (Chrysoperla carnea), were conducted in laboratory conditions (50 ± 1 ˚C 70 ± 5 % RH and photoperiod of L16: D8). In this study wheat aphid had fed on wheat (main host) and oleander (compulsory host) for twenty days. For the experiments we used 3rd and 4th instars of aphids and 2nd instar larvae of green lacewing. The results were compared by each other and oleander aphid (Aphis nerii). Significant effects of host plant and aphid species on feeding rate and longevity of green lacewing were observed. The average feeding rate of 2nd instar larvae of C. carnea on wheat aphid fed on wheat, oleander aphid and wheat aphid fed on oleander were 40.3, 19.5, 30.6 aphids respectively. Also the longevity of 2nd instar larvae of green lacewing which fed on different aphids was recorded as 3.7, 7.8 and 6 days respectively. The results showed that biological characteristics of larvae of C. carnea are influenced by the quality of food which they fed on.

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. -
Heteroptera: Miridae) and a Green Lacewing Chrysoperla Rufilabris (Neuroptera: Chrysopidae), Two Predators of the Azalea Lace Bug (Heteroptera: Tingidae)

Entomol. 31(6): 1184Ð1190 (2002) ABSTRACT Azalea plant bug (Rhinocapsus vanduzeei Uhler) Þfth instars and a commercially obtained green lacewing (Chrysoperla rufilabris Burmeister) Þrst and second instars exhibited a type II functional response when caged with varying densities of fourth or Þfth instar azalea lace bug, Stephanitis pyrioides (Scott), prey. Attack coefÞcients for combined fourth and Þfth instar prey were statistically similar for R. vanduzeei and C. rufilabris (0.052 and 0.057, respectively). The handling time was signiÞcantly greater for R. vanduzeei (3.96 h) than C. rufilabris (2.41 h). Search efÞciency generally declined for both predators as initial azalea lace bug density increased. C. rufilabris killed signiÞcantly more fourth and Þfth instar prey than R. vanduzeei (8.0 and 6.0, respectively) in 24 h. Results indicate that C. rufilabris is a more suitable candidate for augmentative, not inoculative, release for azalea lace bug control than R. vanduzeei. However, R. vanduzeei can effect reductions in azalea lace bug populations in the landscape as a component of the guild of lace bugÕs natural enemies and should be considered in conservation efforts.

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. -

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. -

Dispersal and Opposition Strategies in Chrysoperla carnea By Peter DUELLI (Berkeley and Basel) Summary The flight and oviposition behavior of the holarctic common green lacewing Chrysoperla car- nea (STEPHENS) (Neuroptera: Chrysopidae), has been investigated in alfalfa fields in the Califor- nia Central Valley and in laboratory experiments. In the first two nights after emergence the adult lacewings perform straight downwind disper: sal flights. Take-off behavior is elicited by the decrease in illumination at sunset. Since neither take- off nor the flight duration appear to be influenced by so-called "vegetative" stimuli such as food or mating partners, these pre-ovipository fligths are termed "obligatory migration flights". For the Central Valley an average initial flight distance of 40 km per night was estimated. In the third night after emergence the lacewings start to react anemochemotactically to food kairomons signalling the presence of honey dew. Males and females on their downwind flight are induced to land and approach the food source in a low, stepwise flight against the wind. Females mate in the third or fourth night after emergence and may deposit the first eggs on day 5. The consequence of the pre-ovipository migration flights is that very few females will deposit their eggs in the habitat in which they emerged. Consequently, virtually all eggs deposited in a particular field most probably stem from immigrant females. But even after mating and the onset of oviposition the dispersal activitiy continues. Reproductively active lacewings also take off every night after sunset and perform "appetitive downwind flights" until they enter the scent plume of a food source. -

Chrysopidae, lacewings, Chrysoperla lucasina, Psylloidea, Agonoscena pistaciae, pistachio psylla, population density, weeds, intrinsic rate of increase, theoretical threshold, food consumption, biological control Abstract. Species in the carnea complex of the common green lacewing are predators of the common pistachio psylla, Agonoscena pistaciae in both cultivated pistachio plantations and on wild pistachio plants in Iran. The seasonal occurrence of common green lacewings was monitored in pistachio orchards from 2007 to 2008. In addition, the effect of different temperature regimes on prei- maginal development, survival and prey consumption of the predatory lacewing Chrysoperla lucasina fed on A. pistaciae nymphs were studied under controlled conditions. The adults of common green lacewings first appeared on pistachio trees in mid April and were most abundant in early July, decreased in abundance in summer and increased again in October. The relative density of common green lacewings was higher in pistachio orchards where the ground was covered with herbaceous weeds than in those without weeds. In the laboratory females of C. lucasina laid an average of 1085 eggs over 60 days at 22.5°C. The maximum prey consumption occurred at 35°C when the larvae consumed 1812 fourth instar psyllid nymphs during their larval period. -

Gut Content Metabarcoding Unveils the Diet of a Flower‐Associated Coastal
ECOSPHERE NATURALIST No guts, no glory: Gut content metabarcoding unveils the diet of a flower-associated coastal sage scrub predator PAUL MASONICK , MADISON HERNANDEZ, AND CHRISTIANE WEIRAUCH Department of Entomology, University of California, Riverside, 900 University Avenue, Riverside, California 92521 USA Citation: Masonick, P., M. Hernandez, and C. Weirauch. 2019. No guts, no glory: Gut content metabarcoding unveils the diet of a flower-associated coastal sage scrub predator. Ecosphere 10(5):e02712. 10.1002/ecs2.2712 Abstract. Invertebrate generalist predators are ubiquitous and play a major role in food-web dynamics. Molecular gut content analysis (MGCA) has become a popular means to assess prey ranges and specificity of cryptic arthropods in the absence of direct observation. While this approach has been widely used to study predation on economically important taxa (i.e., pests) in agroecosystems, it is less frequently used to study the broader trophic interactions involving generalist predators in natural communities such as the diverse and threatened coastal sage scrub communities of Southern California. Here, we employ DNA metabarcoding-based MGCA and survey the taxonomically and ecologically diverse prey range of Phymata pacifica Evans, a generalist flower-associated ambush bug (Hemiptera: Reduviidae). We detected predation on a wide array of taxa including beneficial pollinators, potential pests, and other predatory arthropods. The success of this study demonstrates the utility of MGCA in natural ecosystems and can serve as a model for future diet investigations into other cryptic and underrepresented communities.

Consequences of Linguistic Uncertainty for Insect Management
WATCH YOUR LANGUAGE Consequences of Linguistic Uncertainty for Insect Management THERESA M. CIRA, KATHY QUICK, AND ROBERT C. VENETTE JA'CRISPY/ISTOCK 258 AMERICAN ENTOMOLOGIST | WINTER 2019 his is a call to entomologists to consider the un- certainty introduced into our works through the language we use. Albert Einstein remarked, “Every- thing depends on the degree to which words and word-combinations correspond to the world of im- Tpression,” which makes language a “dangerous source of error and deception” (Hawking 2007). Scientists usually research and deliberately choose the language they use to propose new concepts or terminology. Often, however, terms slip into the lexicon through less systematic means. Words may seem to have meanings so obvious that broad understanding of the term may be taken for granted, but individual contexts are diverse, and to assume that a word’s meaning is unchanging across time and space is to overlook the uncertainties of lan- guage. Thus, communication through even the most common entomological vocabulary can fail. Language is a mutable, un- certain, and imperfect way of representing the world. Because language is integral to science and yet inherently imprecise, it is important for scientists to recognize and address uncertain- ty in the language of our works. Uncertainty, as defined by the Society a phenomenon is repeatedly observed and for Risk Analysis (2015), is “not knowing the individuals agree that measurements con- true value of a quantity or the future con- verge, to some degree, on a specific point, sequences of an activity,” or “imperfect or more certainty about the true nature of the incomplete information/knowledge about phenomenon can be asserted.
