The predatory ladybird beetle Tenuisvalvae notata (Coleoptera: Coccinellidae) (Mulsant) is a polygamous species and its morphology, as well as the storage capacity of seminal fluid in the spermatheca, may affect its reproductive performance. Thus, the present study evaluates the spermatheca morphology of virgin and mated T. notata females using light and scanning microscopy. The results show that the spermatheca of T. notata is kidney shaped and consists only of the receptacle and spermathecal duct, being morphologically similar in virgin and mated females. There is no secretion in the spermathecae of virgin females and, in mated females, only once it was not possible to observe the presence of spermatozoa. By contrast, females mate multiple times it is possible to observe spermatozoa in the lumen of the spermatheca surrounding the secreted material. Polygamy in T. notata might be related to the maintenance of viable spermatozoa in the spermatheca, in which case the female would prefer to copulate more times during its adult life than to store spermatozoa for a longer period of time.

“…Isso pode ser justificado em virtude do aspecto afidófago da joaninha, ou seja, apesar da mesma apresentar hábito cosmopolita e predação generalista (França Júnior, 2014), um alimento alternativo fornecido influenciará em problemas na emergência dos adultos com uma relação de machos e fêmeas não esperada na população seguinte. Barbosa et al (2014) O peso dos adultos foi maior (14,7 mg) quando C. sanguinea foi alimentada com H. foeniculi e menor quando foi fornecido ovos de A. kuehniella (Figura 1). O valor para peso da joaninha evidenciado nesse trabalho localiza-se na faixa observada por Santos et al (2003) alimentando C. sanguinea com Schizaphis graminum (Rondani) criados em genótipos de sorgo, cujo menor valor foi de 12,0 mg e o maior de aproximadamente 16,0 mg. Figueira et al (2003) verificaram que o peso de C. sanguinea apresentou-se muito abaixo quando as larvas foram alimentadas com ovos de Bemisia tabaci (Gennadius) (0,08 mg) em relação a alimentação com pulgão S. graminum (11,32 mg).…”

Aspectos biológicos de Cycloneda sanguinea alimentada com pulgões Brevivoryne brassicae, Hyadaphis foeniculi e ovos de Anagasta kuehniella

Resumo -A erva-doce Foeniculum vulgare e a couve Brassica oleracea são importantes plantas medicinais e condimentares, no entanto, o ataque de pulgões prejudica seu cultivo. O controle biológico é uma ferramenta importante na redução da população de insetos-praga. O trabalho teve como objetivo avaliar o desenvolvimento biológico das fases imaturas e o ganho de peso dos adultos de Cycloneda sanguinea alimentada com os pulgões Hyadaphis foeniculi, Brevycorine brassicae e ovos de Anagasta kuehniella, comparando-se os tipos de alimento. A pesquisa foi conduzida em laboratório com temperatura média de 25 ± 2 ºC, umidade relativa de 70 ± 10% e fotofase de 12 h. Utilizaram-se três tratamentos contendo 15 larvas de C. sanguinea. Avaliou-se a duração do período de cada estádio larval; duração do período larval completo; duração dos períodos de pré-pupa e pupa; duração do período de larva a adulto; viabilidade percentual de cada estádio larval, das fases larval, pré-pupal e pupal; razão sexual e peso de adultos da joaninha. As larvas de C. sanguinea desenvolveram-se satisfatoriamente quando consumiram H. foeniculi e B. brassicae, com período de larva a adulto de 10,2 dias e viabilidade pupal de 100%. O peso de adultos foi maior (14,7 mg) no alimento H. foenciuli. O pulgão da erva-doce fornece melhor desenvolvimento larval e peso de adultos de C. sanguinea e os ovos de A. kuehniella, comparados aos pulgões, não são adequados a um bom desenvolvimento da joaninha. Palavras-chave:Produtividade; Desempenho; Planejamento. Biological aspects of Cycloneda sanguinea fed on aphids Brevicoryne brassicae, Hyadaphis foeniculi and eggs of Anagasta kuehniellaAbstract -Fennel Foeniculum vulgare and kale Brassica oleraecea are important medicinal plants and relevant condimental, however, the attack of aphids prejudices their cultivation. The biological control is an important tool to reduce the insect-pest population. The work aimed to evaluate the biological development of immature stages and adult weight gain of Cycloneda sanguinea fed on aphids Hyadaphis foeniculi and Brevicoryne brassicae, and Anagasta kuehniella eggs, comparing the type of food. The search was conducted under laboratory conditions, medium temperature (25 ± 2 ºC), relative humidity 70 ± 10% and photophase 12 h. We used three treatments with 15 replicates. The parameters evaluated were duration of each larval instar, complete larval stage, prepupal stage and pupal stage, sex ratio and weight of adults, as well as percentage of feasibility of each lady beetle stage. The larvae of C. sanguinea develop satisfactorily when they consume H. foeniculi and B. brassicae with 10.2 days of period larval to adult and 100% feasibility of pupae. The weight of adults was higher (14.7 mg) when the ladybugs fed on H. foeniculi, being evidenced the potential of survival under these aphids. The fennel aphid provides better development for larvae and weight gain of C. sanguinea adults and eggs of A. kuehniella, compared with the aphids, are not adequate for good development of the ladybug.

Temperature and prey assessment on the performance of the mealybug predator Tenuisvalvae notata (Coleoptera: Coccinellidae)

Tenuisvalvae notata preys upon several mealybug species (Hemiptera: Pseudococcidae), a group of worldwide pests including Planococcus citri and Ferrisia dasyrilii. Although the consequences of variation in temperature for the development and reproduction of insects are generally appreciated, the consequences of potential interactions between temperature and prey for predatory insects are not. Thermal requirements and predation rates were determined for T. notata at different constant temperatures with both prey species. T. notata larvae developed to adults in experimental conditions > 18 to <38 °C. The upper thermal limit for egg hatch was 34 °C and for pupation was 33 °C. Adults reared at ≥32 °C did not lay eggs and survived less than 1 week. Prey species did not affect lower temperature thresholds or thermal constants for development from egg to adult. Furthermore, prey did not affect a number of reproductive traits, but the interaction between temperature and prey affected changes in developmental times and oviposition rate with age. Predation rate of T. notata increased as a function of temperature, and T. notata adults generally consumed more nymphs of P. citri than F. dasyrilii. These findings indicate that T. notata is well adapted to the tropical and sub‐tropical temperatures and may prove useful for the biological control of some native and non‐native mealybugs.
