Unusual Symptom

During a study of the effects of insecticides on cyclic nucleotide metabolism it was observed that moths (Mamestra conjgurata Wlk.) treated with the pyrethroids permethrin and deltamethrin often had grossly bloated abdomens several hours after treatment.Two- to three-day-old moths were obtained from a laboratory culture of the bertha armyworm, M. configurata, reared on an artificial diet (Bucher and Bracken 1976). Initially, males and females were treated topically with insecticide in 5 μl of acetone applied to the thorax, head, or abdomen. Pyrethroid-treated moths developed abdominal bloat independent of the site of treatment, therefore the thorax was chosen for treatment. Treated moths were held at 20°C and examined twice daily for 3 days to determine the incidence of bloat and mortality.

Effect Of Age

A reprodução de parasitóides apresenta etapas interligadas e a idade de hospedeiros e parasitóides pode afetar o desenvolvimento desses últimos. Características biológicas de fêmeas de Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae), com até 96 horas de idade, foram estudadas em pupas do hospedeiro alternativo Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae). Cada pupa de A. gemmatalis com 0-24, 24-48, 48-72 ou 72-96 horas de idade, foi oferecida ao parasitismo por 10 fêmeas de T. diatraeae com 0-24, 24-48, 48-72 ou 72-96 horas de idade, por 24 horas à 25 ± 2oC, umidade relativa de 70 ± 10% e fotofase de 14 horas. A emergência, o número de descendentes, a duração do ciclo, a razão sexual, a longevidade e largura da cápsula cefálica de machos e de fêmeas de T. diatraeae apresentaram resposta semelhante para o efeito idade das pupas desse hospedeiro e fêmeas desse parasitóide em conjunto. No entanto, houve redução da emergência, número de descendentes e longevidade das fêmeas de T. diatraeae com duração do ciclo se ajustando a uma função quadrática quando se avaliou apenas o efeito da idade do parasitóide. Pupas de A. gemmatalis, com até 96 horas de idade, podem ser usadas para criação massal de T. diatraeae utilizando-se fêmeas desse parasitóide com até 96 horas de idade.Reproduction of Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae) on Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) Pupae in Relation to  Age of the Parasitoid and HostAbstract. Reproduction of parasitoids presents interconnected steps and the ages of hosts and parasitoids can affect the development of parasitoids. Biological parameters of Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae), at up to 96 hours of age were studied on pupae of the alternative host Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) pupae. Each A. gemmatalis pupae from 0-24, 24-48, 48-72 or 72-96 hours of age, was offered to parasitism to 10 females of T. diatraeae at 0-24, 24-48, 48-72 or 72-96 hours of age for 24 hours at 25 ± 2°C, relative humidity of 70 ± 10% and photophase of 14 hours. Emergency, number of offspring, length of cycle, sex ratio, longevity and width of cephalic capsule of males and females of T. diatraeae showed similar response when effect of age of pupae and females of parasitoid were evaluate jointly. However, emergency, number of offspring and longevity of females of T. diatraeae were reduced as length of cycle was being adjusted to a quadratic function when only effect of age of parasitoid was evaluated. Pupae of A. gemmatalis with up to 96 hours of age can be used for mass rearing of T. diatraeae using females at up to 96 hours of age.

The description of Agrotis colossa as sp. n. became necessary, since the original description has never been published and the manuscript was not found in the Boursin heritage. The original name and designation was accepted, however, the type material (holotype male and single allotype female) was completed with a series of males and females from the recent expeditions. The description of Agrotis rachingeri sp. n. is also given and the DNA results in case of both species. New taxa are illustrated with imagines in colour and male and female genitalia.

Abstract. Saura EBD, Falcasantos GC, Andante RJM, Munda LC, Alimorong MM, Hernando BJ. 2021. Evaluation of fluctuating asymmetry and sexual dimorphism of Channa striata using landmark-based geometric morphometric analysis from Agusan Marsh and Lake Mainit in Caraga Region, Philippines. Nusantara Bioscience 13: 100-110. Evaluation was conducted to determine the impact of ecological condition to Channa striata using fluctuating asymmetry (FA) employing the landmark-based geometric morphometric analysis, using TPS software, SAGE, PAST-Hotellings Test, including Physico-chemical analysis, cyanide and four base metals. Results of Physico-chemical analysis of the two habitats showed Agusan marsh with low oxygen level (3.37-4.55) and high in Iron and TDS as compared to DENR Standards. The statistical results showed high variations (p < 0.0001) on left and right-side having percentage of 79.22% in Agusan Marsh and 72.35% in Lake Mainit which is relatively high Fluctuating Asymmetry. In terms of sex, Agusan marsh had 84.27% and 85.41% FA in males and females while Lake Mainit having 85.12% and 80.89% in males and females. The fairly similar percentage of Fluctuating Asymmetry confirms no sexual dimorphism and no shape differences between male and female, and no peculiar characters to distinguished between sexes based on the 17 landmark points. Present study concluded that FA observed in the snout tip was due to breeding behavior, the landmark points in cephalic, pectoral, and caudal region were associated with burrowing and mobility factors within the lateral line system in these fishes which thrive in high turbid habitat and low oxygen. Furthermore, it was found that the level of FA tends to increase in disturbed environs.

A lagarta Spodoptera frugiperda (Smith) é praga-chave da cultura do milho e a cada ano sua ocorrência na cultura algodoeira têm aumentado, causando danos severos desde a fase de plântula até a maturação. Objetivou-se com este trabalho avaliar o efeito do silício na biologia de S. frugiperda em algodoeiro de fibra branca e colorida. Os bioensaios foram conduzidos com duas cultivares de algodão, a BRS Cedro (fibras brancas) e BRS Verde (fibras verdes), com e sem aplicação de silício. O silício foi aplicado como solução de ácido silícico a 1 %, na dosagem equivalente a 3 t/ha de SiO2. Avaliaram-se os seguintes parâmetros biológicos: mortalidade larval, duração da fase larval e pupal, viabilidade de pupa, peso das pupas, razão sexual, longevidade dos adultos, machos e fêmeas e o número de ovos/fêmea. Verificou-se que a aplicação de silício aumentou apenas a mortalidade de lagartas alimentadas com folhas da BRS Cedro, não demonstrando nenhum efeito nas lagartas quando aplicado na BRS Verde. Além disso, na cultivar BRS Cedro, em comparação com a cultivar BRS Verde, houve menor peso de pupa e menor produção de ovos/fêmea. Biology of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in Colored Cotton Treated with Silicon Abstract. The caterpillar Spodoptera frugiperda (Smith) is a key pest of the corn culture and each year its occurrence in the cotton culture has increased, causing severe damage from the seedling phase to maturation. The objective of this work was to evaluate the effect of the silicon on the biology of S. frugiperda in white and colored fiber cotton plants. The bioassays were conducted with two cultivars of cotton, BRS Cedro (white fibers) and BRS Verde (green fibers), with and without silicon application. The silicon was applied as a solution of 1% silicon acid, at a dosage equivalent to 3 ton/ha of SiO2. The following biological parameters were evaluated: larval mortality, duration of the larval and pupal phase, pupal viability, pupal weight, gender ratio, adult longevity of males and females and the number of eggs/female. It was verified that the silicon application only increased the mortality of caterpillars fed with BRS Cedro leaves, not demonstrating any effect on the caterpillars when applied on BRS Verde. Furthermore, the BRS Cedro cultivar, when compared to the BRS Verde cultivar, presented a lower pupal weight and a lower eggs/female production.

Abstract The present study was based on the idea of a pheromone trap barrier with alternating dispensers releasing different pheromone mixtures that affect males and females differently. We tested the possibility of increasing the catch efficacy of pheromone trap barriers by altering the pheromone mixture with low levels of cis-Verbenol (cV, targeting males, BM), the mixture with high levels of cV (targeting females, BF) and the pheromone mixture with intermediate levels of cV (SL). In addition, we were interested in lowering the dispersion of attracted bark beetles, especially males, which reduces the risk of attack on trees in the surroundings. Significant highest absolute and relative catch was found in the catch of the combination BM–BF, which was 2.2-fold higher than the catch of the control barrier treated with commercial IT Ecolure baits (Fytofarm, Slovakia). At the same time, the lowest dispersal in the surroundings of the barrier with the combination BM–BF was found, which was 2.5-fold lower than in the control barrier. The performance of the BM–BF combination of mixtures was proved in a field trial experiment where the total season catch of the part of the barrier treated with BM–BF dispensers caught 1.5-fold more beetles during the season than the control part treated with IT Ecolure dispensers. Furthermore, the results confirm that the performance of the combination of low levels of cV (targeting males) and high levels of cV (targeting females) is complemented by the desired reduced dispersion around the barrier, which reduces the risk of attack on trees in the surroundings.
