“…The average larval period of the first instar at 30°C was 2.9 days. The results of our study are partially supported by the results of Bezerra et al [21] who investigated that survivor, mortality and development of life stages of green lacewing, Chrysoperla genanigra varied significantly at constant temperatures (17,21,25,29,33, 35 and 37 °C), a photoperiod of 12 h: 12 h (L: D) and 70 ± 10% relative humidity.…”

A laboratory study was conducted to evaluate the influence of different temperatures on life stages of Chrysoperla carnea (Stephens) on frozen eggs of Sitotroga crealella. The study was conducted under laboratory conditions at Department of Plant Protection, SAU, Tandojam Sindh, Pakistan during 2013-14. The result revealed that the maximum hatching 88 % of eggs was recorded at 28 ºC followed by 25, 31, 22, 34 and 37 ºC. The highest mortality (dx) was recorded in first instar at 34 ºC followed by at 22, 31, 37, 25 and 28 ºC, whereas, minimum (dx) was recorded in third instar and pupal stages as well. The highest and lowest apparent mortality (100qx) was observed in the first instar and egg stages at 37 ºC. The data further depicted that the highest survival fraction (Sx) was recorded as (0.98) in second instar, third instar and pupa at 28 ºC, whereas, the lowest (Sx) was observed as (0.13) in the first instar at 37 ºC. The maximum indispensable mortality (IM) was 42 in egg stage at 37 ºC and lowest 1.0 in pupal stage at all temperature regimes. The number of the surviving at the beginning of the stage (lx) was highest 39 adults emerged at 28 ºC followed by 31, 24, 20 and 5 adults emerged at 25, 31, 22 and 34 ºC, respectively. On the other hand, minimum total generation mortality (K) was recorded as 0.11 at 28 ºC followed by 0.21, 0.32, 0.40, and 1.00 at 25, 31, 22 and 34 ºC, respectively. The minimum duration from egg to adult emergence was 12.0 days at 34 ºC and maximum 23.5 days at 22 ºC. There was significant difference between the duration and treatments (P<0.05). It is concluded that the maximum mortality was recorded at 37 ºC in egg and first instar stages, no any stage was survived after second instar. The temperature ranges from 25 to 31 ºC have been proved suitable for the development of C. carnea.. However, 1 st and 2 nd instar survived for short period at 37 ºC only.

“…The thermal constant observed in honey + bee pollen diet is similar to that reported for C. raimundoi (LAVAGNINI et al, 2009). Bezerra et al (2012) found values of Tb = 11.08 and K = 51.39 for Chrysoperla genanigra Freitas, 2003 (Neuroptera: Chrysopidae)…”

“…It is observed in literature recommendations and optimal temperature ranges for feasibility of lacewing eggs, between 20 and 25 °C (PESSOA et al, 2009;BEZERRA et al, 2012). Diet based on molasses and brewer's yeast provided 100% of feasibility at temperatures between 27 °C and 31 °C.…”

Green lacewings can be mass reared to market their eggs. The ideal temperature is a main factor for egg storage or scheduling of insect production. This study aimed to evaluate the influence of Ceraeochrysa cubana adult feeding on incubation period and feasibility off eggs storage under different temperatures. Adults were submitted to four artificial diets: honey + brewer's yeast (standard diet), molasses + brewer's yeast, honey + bee pollen and molasses + bee pollen. Incubation period was recorded keeping eggs at six different temperatures: 21, 23, 25, 27, 29 and 31 °C. requirements. We determined the duration of the incubation period and egg feasibility of C. cubana. In addition, we estimated the base temperature (Tb) and thermal threshold (K) for the green lacewing incubation. Regardless of diet, incubation period decreases according to increased temperature, which is indicated between 21 and 29 °C for better development and egg feasibility. Adult feeding influences thermal constant, however, does not influence base temperature of the eggs, which varies from 15 to 18 °C. Our results can serve as a basis for the choice of adults' diet and temperature for the storage of eggs during the mass rearing of C. cubana.

“…Studies about the toxicity of chemicals on this species are scarce and not yet published, however, a biology study conducted by Bezerra et al (2012) showed that under temperature of 25°C, relative humidity of 65%±10 and photoperiod of 12 hours, C. genanigra females had approximately 2.22 eggs female -1 day -1 . These values were lower than those found in the present study, probably because of the feed used by these authors in the larval stage, namely, eggs of Sitotroga cerealella Oliver, 1789 (Lepidoptera: Gelechiidae).…”

-Brazil is one of the world's largest producers of melon (Cucumis melo L.), and Rio Grande do Norte and Ceará are the largest producers states of the country (99% of exports). This crop had great socioeconomic importance in the Brazilian Northeast, however, it is affected by insect pests and consequently, large amounts of pesticides are applied to it, which greatly affect beneficial organisms, such as Chrysopidae. This bioassay evaluated the toxicity of nine insecticides used in commercial crops of muskmelon, applied to firstinstar larvae of Chrysoperla genanigra of up to 24-hour-old, from mass rearing cultures. Sublethal effects were evaluated, classifying the insecticides into the toxicity classes recommended by the IOBC. A completely randomized design was used, consisting of ten treatments (clothianidin, pymetrozine, lambda-cyhalothrin, chlorantraniliprole, indoxacarb, pyriproxyfen, beta-cyfluthrin+imidacloprid, imidacloprid, beta-cypermethrin and a control consisted of distilled water). The treatments consisted of exposure of thirty larvae to dry residues of each product in Petri dishes, assessing their mortality, duration of instars, sex ratio, fecundity and viability of eggs from adults of the insects evaluated. The products were classified in toxicity classes as harmful (Class 4) (clothianidin, pymetrozine, indoxacarb, lambda-cyhalothrin, beta-cyfluthrin+imidacloprid, imidacloprid, betacypermethrin and pyriproxyfen) and innocuous (Class 1) (chlorantraniliprole) to first-instar larvae of C. genanigra, by calculate their total effect. Based on this work, chlorantraniliprole is the only recommended insecticide for use in integrated pest management (IPM) programs in muskmelon crops.Keywords: Green lacewings. Predator.

TOXICIDADE DE INSETICIDAS UTILIZADOS NO MELOEIRO SOBRE PRIMEIRO INSTAR DEChrysoperla genanigra FREITAS (NEUROPTERA: CHRYSOPIDAE) RESUMO -O Brasil é um dos maiores produtores de melão (Cucumis melo L.), tendo os estados do Rio Grande do Norte e Ceará os maiores representantes (99% das exportações), com enorme relevância do ponto de vista socioeconômico para a região nordeste. No entanto, a cultura é acometida por insetos-praga, razão pela qual grandes quantidades de agrotóxicos são necessárias os quais afetam sobremaneira organismos benéficos como os crisopídeos. O bioensaio avaliou a toxicidade de nove inseticidas utilizados comercialmente na cultura do meloeiro, aplicados sobre primeiro instar larval de Chrysoperla genanigra, avaliando, inclusive, efeitos subletais, categorizando os inseticidas em classes de toxicidade preconizadas pela IOBC. Foram utilizadas larvas com até 24h de idade, oriundas de criação massal. Utilizou-se o delineamento inteiramente casualizado, composto por dez tratamentos: clotianidina, pimetrozina, lambda-cialotrina, clorantraniliprole, indoxacarbe, piriproxifem, beta-ciflutrina + imidaclopride, imidaclopride, beta-cipermetrina e a testemunha constituída de água destilada. Cada tratamento consistiu na exposição de trinta larvas aos resíduos ...
