“…Genotype 'IAC PL-1' shortened the egg stage duration to 2.2 days. These results are inferior to those obtained by Magrini et al (1996), who observed a mean incubation of 3.3 days at 27ºC, for eggs laid by adults whose caterpillars were reared on artificial diet.…”

A knowledge of the mechanisms of resistance present in genetic materials should help breeding programs in developing cultivars resistant to insects. The biology of Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) was studied on leaves of four soybean genotypes with different degrees of resistance to insects. The genotypes evaluated were cultivars IAC 17 and IAC 24, resistant to defoliators and stink bugs, line PI 229358, a source of multiple resistance to insects and used as parent in various lines selected for resistance to A. gemmatalis, and 'IAC PL-1', the susceptible control. The experiments were carried out in the laboratory, under controlled conditions of temperature (25 ± 2ºC), relative humidity (60 ± 10%) and photoperiod (14h). First instar larvae were placed in Petri dishes and fed leaves of each genotype, detached from plants at the R1 and R2 stages (beginning and full bloom). Later on, insect couples were maintained in 25 PVC cages to evaluate parameters of the adult stage. 'IAC 17' and 'IAC 24' promoted low viability of the larval, pupal, and egg stages, causing adult deformation and a reduction of the number of eggs per female. PI 229358 prolonged the immature stage and reduced pupal weight, egg viability, and adult longevity. Considering all tests, 'IAC 17' and 'IAC 24' were characterized as having antibiosis-type resistance, and 'IAC PL-1' demonstrated to be a genotype suitable for insect development.

“…De modo geral, as temperaturas extremas foram mais prejudiciais ao desenvolvimento das lagartas, o que está de acordo com o observado para S. eridania (Foerster & Dionísio 1989) e para P. sequax (Foerster 1996), para as quais a mortalidade larval foi maior nas temperaturas extremas. Para A. gemmatalis apenas a temperatura extrema inferior (18ºC) afetou a sobrevivência das larvas (Magrini et al 1996).…”

“…A sobrevivência das pupas de S. eridania foi de 100% nas temperaturas de 17°C a 25°C, ocorrendo pequena mortalidade (4,8%) à temperatura de 30°C (Foerster & Dionísio 1989); A. gemmatalis não apresentou diferenças significativas na sobrevivência das pupas, exceto para fêmeas mantidas a 18ºC (Magrini et al 1996). A viabilidade do período ovo-adulto foi muito baixa em todas as temperaturas estudadas, principalmente em função dos baixos valores obtidos para a fase de ovo (Tabela 3).…”

-The biology of Spodoptera cosmioides (Walk.) was studied under different temperatures and its thermal requirements were determined, aiming to aid the rearing of this insect in the laboratory. Embryonic and post-embryonic periods were evaluated at seven different temperatures (14, 18, 22, 25, 28, 30 and 32ºC) under environmental chamber conditions, with 14h photophase. The caterpillars were reared on an artificial diet containing white bean, soybean meal, yeast extract, wheat germ and powder milk as source of protein. The extent of the embryonic period decreased with the increase of temperature within the 14ºC to 25ºC temperature range, remaining constant between 28ºC and 32ºC. For the other phases (caterpillar, pre-pupa and pupa) an inverse relationship between temperature and duration was observed within the 14ºC to 30ºC temperature range, extending to 32°C for pupae. Duration of pupal phase for males was larger than for females resulting in asynchronous adult emergence. The temperature thresholds for the embryonic, larval, pre-pupal, pupal periods and total cycle were 9.34ºC, 11.65ºC, 9.65ºC, 11.08ºC and 11.23ºC, with thermal constants of 62,73 degree-days (DD), 254.61DD, 33.42DD, 177.55DD and 525.11DD, respectively. Evaluating the pupal phase alone, the threshold temperatures were 11.25ºC for males and 10.81ºC for females, with thermal constants of 188.26DD for males and 165.47DD for females. For total cycle, the threshold temperature and the thermal constant for males were 11.28ºC and 535.85DD, whereas for females the same variables had values of 11.15ºC and 513.17DD. So, the most adequate temperature for the development of S. cosmioides is within the range of 25ºC and 28ºC, where 9.6 to 11.7 generations of the insect can be annually obtained, in laboratory conditions. KEY WORDS: Insecta, bioecology, threshold temperature, thermal constant. RESUMO -O objetivo do trabalho foi estudar a biologia de Spodoptera cosmioides (Walk.) em diferentes temperaturas e determinar suas exigências térmicas, visando fornecer subsídios para a criação do inseto em laboratório. Para isso, os períodos embrionário e pós-embrionário foram avaliados em sete temperaturas (14, 18, 22, 25, 28, 30 e 32ºC), em câmaras climatizadas, com fotofase de 14h. As lagartas foram criadas em dieta artificial, tendo como fontes protéicas feijão branco, farelo de soja, levedura de cerveja, germe de trigo e leite em pó. A duração do período embrionário decresceu com o aumento da temperatura na faixa de 14°C a 25°C, mantendo-se constante entre 28°C e 32°C. Para os demais estágios (lagarta, pré-pupa e pupa), foi observada uma relação inversa entre a temperatura e a duração na faixa de 14°C a 30°C, estendendo-se a 32°C para pupas. A duração da fase de pupa dos machos foi maior do que das fêmeas, o que promoveu assincronia na emergência de adultos. As temperaturas bases do período embrionário, fase de larva, pré-pupa, pupa e ciclo total foram 9,34°C; 11,65°C; 9,65°C; 11,08°C e 11,23ºC, com constantes térmicas de 62,73 graus-dia (GD); 254,61 GD...

“…After pupation, the pupae were sexed and weighed 24 h after pupation, and the survival rate of each instar was calculated. The adults were placed in acrylic cages (34 cm × 34 cm × 47 cm) immediately after emergence (Magrini et al ) to enable nuptial flight and reproduction. These cages were lined with paper towels and included containers for food (vitamin solution and beer) and water.…”

Bioecological characteristics of Chrysodeixis includens (Lepidoptera: Noctuidae) fed on different hosts

Chrysodeixis includens (Walker 1858), also known as soybean looper, is a polyphagous pest with increasing economic significance in various crops. The rate of infestation and its distribution can be influenced by feeding through direct and indirect effects on their life cycles. Thus, this study aimed to examine the biological characteristics, food preference and leaf consumption of C. includens on soybean (BRS 284), cotton (FMT 701), sunflower (BRS 323) and common morning glory leaves (Ipomoea sp.) as possible host plants. The experiments were conducted with specimens obtained from mass rearing in the laboratory. C. includens larval and larval-adult stages were shorter in sunflower and longer in cotton. Also, larval preference was greater for sunflower and lower for cotton leaves. Soybean leaves were consumed the least in contrast to sunflower and common morning glory leaves, which were consumed the most. These results suggest that soybean, sunflower or common morning glory leaves were favourable hosts for C. includens development, whereas cotton leaves are less nutritionally adequate for insect development. In addition, sunflower leaves reduce C. includens development time and promotes a survival rate greater than 95%, and the leaves are more attractive to larvae when compared with the other tested hosts. This indicates sunflower is the most favourable host among the tested plants for C. includens.
