Lacewings (Chrysopidae: Neuroptera) are predatory insects, widely used in biological control programs. Between them green lacewing is a promising biological control agent of pests in green houses and crop fields. In this study, gravid females of the green lacewing C hrysoperla lucasina (Lacroix) were captured from Sarepolzahab ( altitude 540m, latitude 34°,14´ N 46°,9´ E) in western part of Iran. Collected insects were reared in a growth chamber, under experimental conditions (25±1°C, 70±5% RH and a photoperiod of 16:8 L: D). Different diets were offered to larvae which consisted of a whitefly species B.tabaci , an aphid Myzus persica and also lyophilized powder of drone honeybee ( Apis melifera ). As different foods were used to nurish larvae, so for each diet, mean larval period were calculated, and finally means were compared to each other. Anova in MSTAT-C was used for analysis of variance, and Duncan multiple range test (DMRT) to compare between means. The results showed that larvae had maximum duration of 27±0.33 days when fed on honeybee lyophi- lized powder and the minimum value was 17.9±0.3 days for B. tabaci . 25±0.27 day recorded for M. persicae . Food preference of the 3 rd instar larvae of green lacewing was surveyed, they showed a food preference to M. persicae , to compare with B. tabaci , as the former has a bigger body size, so more easily to be captured by the predator larvae. The 3 rd instar larvae of lacewing were more voracious on preys, than the 1st or the 2 nd instar larvae. Statistically speaking, there were a significantly difference when mean of different preys consumed by predator larvae were compared. We found, that when the predator larvae have fed on B.tabaci , their development time was shorter, and when arrived to adult stage, the adults showed, an improved fertili- ty. The results indicated that the suitable prey not only can increase the rate of through accelerating devel- opmental stages of the predator and by means of an increase in its pupal body weight consequently promoting the fecundity of resulting adults, but also can alter predators population density in relation to own production numbers. Key words : C hrysoperla lucasina , Bemisia tabaci , Biological control INTRODUCTION Bemisia tabaci is a plant sap sucking insect belonging to the family Aleyrodidae. It is broadly polyphagous, feeding on an estimated 500 plants species (Greathead, 1986) from 60 plant families (Mound and Halsey, 1978, Jiang et al ., 1999, Hilje et al ., 2001). Since the early 1980’s it has caused escalating problems to field and protected agricultural crops and ornamental plants in the world. Heavy infestations of B.tabaci may reduce host vigor and growth, cause chlorosis and uneven ripening and induce physiological disorders. The larvae produce hon- 636 eydew on which sooty moulds grow, reducing the photosynthetic capabilities of the plant, resulting in defoliation and stunting. B.tabaci is also a vector of 111 plant viruses, some of which are of high economic importance. Resistance to approximately 35 active ingredients has been reported for B.tabaci in at least 20 countries worldwide (Roditakis, 2005). Chrysopids are polyphagous predators that can suppress population of many pest species (Hydron, 1971) such as whiteflies, thrips and leafhoppers (Plincipi and Canard, 1984). Their efficacy in biological control of whiteflies and aphids as well as other arthropod pests has been recognized for more than 250 years (Pappas, et al . 2011). These polyphagous predators can be easily reared on artificial diets and used for controlling agricultural insect pest (Cohen and Smith, 1998). For every biolo gical control, to be successful, primarily, it’s of outmost importance, to evalu- ate the potential of the predator for targeted preys ( Al-Zyoud and Sengonca, 2004). In this study different diets offered to larvae and longevity of life for each larval instars and food preference were evaluated. Analysis of variation was done by using ANOVA and com- paring between means by Duncans multiple range test (DMRT), utilizing MSTAT-C software. MATERIALS AND METHODS Adult insects of C. lucasina were collected by netting from fields of sare-polezahab (altitude 540 m, 34°, 14´N46°.9´E) in western part of Iran. Rearing was carried out in UPVC pipes (height 20, diameter 15 cm) after species discrimination. 10% honey was used as diet for ovipositing adults, the eggs were collected on paper sheets. Deposited eggs were collected daily and transported to cold chamber (5-6°C). Experiments started with transport of egg to growth chamber (25±1°C, 16L: 8D and 70±5% RH). First instar larvae hatched after an incubation period and reared on artificial diet after 1-12 hours. In rearing, different diets offered to larvae consisted of a whitefly species B. tabaci , an aphid M. persica and also lyophilized powder of drone honeybee ( Apis melifera ). Consumption rate of different diets used in this study were carried out in 5 replications in each 2 treatment based on completely randomized design. Nymphs of B. tabaci and M. persicae were used as live. Larval development and nymph consumption rate was counted each 12 hours with considering different foods used. Longevity for each larval instar was evaluated. Analysis of variation and comparing between means carried by use ANOVA and duncan multiple range test (DMRT) respectively. RESULTS AND DISCUSSION The biology and behavior of C. lucasina larvae is dependent on the quality of food which they fed on. Consumption rate of different larval instars of green lacewing ( C. lucasina) on B. tabaci and M. persicae showed maximum larval consumption. Analysis of variation showed maximum larval differences between preys at level of 1% (table 1a and 1b). The results of life history experiments showed that C .lucasina was able to develop and reach the adult stage by feeding on mean 444.2 and 281.8 third instars of B.tabaci and M. persicae, respec- tively. Consumption rate of different larval instars is showed in Table 1a. The result shows signifi- cant difference between larval instars at 5% level. As it is seen from Table 1a, the highest feeding rate of the lacewing belonged to the 3 rd instar larvae Longevity of larval duration on B. tabaci , M. persicae and lyophilized powder of A. melifera was investigated. The results showed significant difference between B. tabaci and other Comm. Appl. Biol. Sci, Ghent University, 77/4, 2012 637 diets at level 1% ( table 2a and 2b). Longevity of larvae had maximum duration 27±0.33 days when fed by honeybee lyophilized powder and minimum 17.9± 0.3 days was recorded for B. tabaci . 25±0.27 days recorded from M. persicae . Alikhan and Wan (2004) reported 18.6 days for larval duration C. pallens feeding on B. tabaci. Food preference of 3 rd instars green lacewing larvae between live preys was investigated. Results showed 70±1.7 and 27.6±2.86 for M.persicae and B.tabaci respectively. When fertility of adults emerging from those larvae which fed on different diets was com- pared, those females who were fed on B.tabaci had a higher fertility rate, so we could con- sider, that for rearing in experimental purpose, it to be a more suitable host for lacewing larvae than other preys. This study showed, that using larvae of green lacewing C. lucasina , is a very good way to control B. tabaci , although we used laboratory conditions, but potentially, it could be used in greenhouses and even in crop fields to control this pest.

    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.

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.

  • December 2019 Suzanne Burgess and Joanna Lindsay
    December 2019 Suzanne Burgess and Joanna Lindsay Saving the small things that run the planet Summary Of the 70 species of lacewing recorded in the United Kingdom, at least forty-one of them have been recorded in Scotland, with four only being recorded in Scotland. The Bordered brown lacewing (Megalomus hirtus) was previously known from only two sites in Scotland, at Salisbury’s Crags in Holyrood Park, Edinburgh and at Doonie Point by Bridge of Muchalls in Aberdeenshire. Scottish Natural Heritage (SNH) provided funding to Buglife for year two of the Bordered Brown Lacewing project to run surveys and workshops to raise awareness and improve participant’s identification skills of the different species of lacewing and their allies (alderflies, scorpionflies and snake flies). With the help of volunteers, year two of the project successfully found twenty two adults of the Bordered brown lacewing. Two new areas were discovered at Holyrood Park at rocky outcrops close to St. Anthony’s Chapel and a new population was discovered at Skatie Shore and Perthumie Bay by Stonehaven. A further nine adults were found by Dr Nick Littlewood at six locations from the war memorial south of Stonehaven to Portlethen Village. A total of 264 records of 141 different species of invertebrate, including five species of lacewing, were recorded during surveys and workshops run through this project from six sites: Holyrood Park, in Edinburgh; Hermitage of Braid and Blackford Hill Local Nature Reserve in Edinburgh; Skatie Shore and Perthumie Bay by Stonehaven; Doonie Point by Bridge of Muchalls; St Cyrus National Nature Reserve near Montrose; and Drumpellier Park in North Lanarkshire.

  • Neuroptera, Chrysopidae) of the Azores Archipelago, Through Morphology Analysis
    Biogeographic origin of the common green lacewings (Neuroptera, Chrysopidae) of the Azores archipelago, through morphology analysis MARIA A. VENTURA, D. THIERRY, P. LOURENÇO & D. CODERRE Ventura, M.A., D. Thierry, P. Lourenço & D. Coderre 2007. Biogeographic origin of the common green lacewings (Neuroptera, Chrysopidae) of the Azores archipelago, through morphology analysis. Arquipélago. Life and Marine Sciences 24: 23-31. Due to a great dispersal ability and small size, insects are probably among the first island colonisers. Chrysoperla carnea sensu lato was for long considered the sole member of the Chrysopidae family in the Azores (Portugal) since it has been regarded as a complex of sibling species in Europe and North America. Its separation into different morphotypes is based on a set of pre-determined morphological traits. Their analysis leads to appraise Azorean Chrysopidae origin, comparing insular and mainland populations. Two outside “carnea complex” species, namely the Nearctic C. rufilabris and the Neotropical C. externa, were also examined to validate the method. Data analysis resulted in grouping separately the two out-group species as expected, and clearly joins insular and Palaearctic specimens of C. lucasina. Chrysoperla agilis, although known to be present in the Azores through courtship song analysis, is morphologically similar to the two other Palaearctic species, which confirms the continental Palaearctic origin of the common green lacewings in the Azores. Madeira has probably served as a stepping-stone to the Azorean colonisation. Key words: Chrysoperla carnea, Macaronesia, morphotypes, Palaeartic origin Maria A.

  • Seasonal Adaptations of Green Lacewings (Neuroptera: Chrysopidae)
    REVIEW Eur. J. Entomol. 102: 317–324, 2005 ISSN 1210-5759 Seasonal adaptations of green lacewings (Neuroptera: Chrysopidae) MICHEL CANARD 47 chemin Flou de Rious, F-31400 Toulouse, France; e-mail: [email protected] Key words. Chrysopidae, green lacewing, seasonal adaptation, diapause, voltinism, overwintering, cycle synchronization, wintering chambers Abstract. Seasonal adaptations of green lacewings (Neuroptera: Chrysopidae) and their role in the control of aphid populations are discussed. The chrysopids of temperate zones face seasonal changes and must escape cyclic adversity. One way is via the number of broods per year. Most green lacewings are facultatively multivoltine, with the succession of generations most often regulated by photomediated diapause. Others are univoltine and some extend their life-cycle to two years in cold or dry environments. Synchroni- zation is an important feature of seasonality, often starting in spring. In univoltine species, it is sometimes the result of subtle mecha- nisms, such as double contradictory signals (short plus long day lengths) for reactivation in spring, or a multi-receptivity of the preimaginal instars to photoperiod throughout a year, combined with photo-controlled and synchronized egg laying in late summer. Only one North American species is known to enter a surnumerary food-mediated diapause in summer. Every postembryonic instar may undergo diapause depending on the species. The timing and impact of the spring resumption in aphid consumption depends on their overwintering strategy. As far is known, chrysopids are intolerant of freezing, but their supercooling points are low enough to enable them to endure hard frost. The numbers of overwintering specimens of green lacewings in the field depend on the structure of the assemblages in the pre- vious growing season.
