“…Fourth‐ and fifth‐instar larvae of B. longissima consumed more leaves than the younger instar larvae. This tendency, drastic increase of food consumption in late‐stage larvae, has also been shown in Lepidoptera (Katayama & Sano 1989; Nava & Parra 2002). We measured the daily leaf consumption of B. longissima larvae only one day in each instar and our estimation (44.3 cm 2 ) may be overestimated because feeding amount may vary within the same instar depending on its age.…”

The coconut hispine beetle Brontispa longissima has been causing serious damage to the coconut palm Cocos nucifera in the Pacific, and Southeast and East Asia. This beetle also attacks Satakentia liukiuensis, an endemic palm on Ishigaki and Iriomote Islands, Japan. To assess the potential impact of B. longissima on S. liukiuensis, we examined the development period, survival rate, egg production and body size of B. longissima on S. liukiuensis at 22–31°C and consumption of S. liukiuensis leaf at 28°C. We also examined these life history traits on C. nucifera at 28°C to compare with those on S. liukiuensis. Brontispa longissima completed their development and reproduced on S. liukiuensis at 22–30°C. Linear regression analysis was used to estimate the effective cumulative temperature (k) as 891.2 degree‐days, and the lower developmental threshold as 13.3°C. On the basis of these values and monthly average temperatures on Ishigaki Island, it was estimated that B. longissima has four generations per year on the island. Satakentia liukiuensis was less suitable for B. longissima than C. nucifera in terms of immature survival, development time, resultant adult size and reproduction. The low quality of S. liukiuensis as a host‐plant may prevent the outbreak of B. longissima, which has not occurred yet on Ishigaki and Iriomote Islands.

“…This result is consistent with the previous observation of damage caused by A. fusca on oil palm trees (Genty 1972). This tendency, drastic increase of food consumption in late-stage larvae, has also been shown in Lepidoptera (Crawley 1989, Nava andParra 2002). We estimated the amount of leaf consumption by A. fusca larvae over their develop ment (first to tenth instar) as 402.31 cm2.…”

The development, life history, and fecundity of Acharia fusca Stoll (Lepidoptera: Limacodidae), an important oil palm pest, was studied at various treatments of temperatures ranging from 10 to 40°C, at a constant relative humidity of 75 ± 5% and a photoperiod of 12:12 (L:D) h. In addition, the amount of leaf consumed by larval instars was measured. Females and males successfully developed into adults within 15-35°C. However, no eggs were found at 10°C, and all adults died after exposure to 40°C. The developmental time from egg to adult ranged between 170.5 d at 15°C and 76.6 d at 35°C (Ei 97 = 56.2; P < 0.0001). Tem perature had a strong effect on the survivorship of A. fusca from the egg to adult emergence, increasing between 15 and 20°C, peaked at 25-30°C, and then declined slightly at 35°C. The different periods of the insect's total reproductive life varied betw een 15 and 35°C, with the preoviposition periods ranging betw een 6.82 and 3.24 d, the oviposition period betw een 17.5 and 4.89 d, and the postoviposition period between 5.29 and 0.82 d. Female longevity was greater than male longevity at all temperatures. The total amount of leaf area consumed by one larva was 402.31 cm2. The results indicated that the development period from egg to adult death at the decreased with increasing tem perature and the larvae maintained a high consumption rate on Elaeis guineensis Jacquin leaves. The effect of tem perature on development, survival, and reproduction of A. fusca can be useful for predicting its long-term population fluctuation as an invasive pest of oil palm plantations.

“…However, it is important to take in consideration the importance of the identification of the caterpillar due the different capacity for leaf consumption of different species (BEACH & TODD, 1988;NAVA & PARRA, 2002;FRANCO et al, 2014), their reproductive potential (MONTEZANO et al, 2013), and the spatial distribution of the different species in the host plant (PANSERA DE ARAÚJO et al, 1999).…”

-Aiming to verify the presence of eggs parasitoids of the genus Trichogramma, for using in the biological control of insects pests, were collected eggs from long tailed skipper butterfly, a lepidopteran defoliator of snap beans, which presented eggs with parasitism characteristics (dark eggs). The eggs were taken to the laboratory were 44.9% of parasitism was verified. Viability was 96.3%, with an average of 6.6 individuals per egg and a sexual ratio of 0.93. Male specimens were identified as Trichogramma bruni Nagaraja. It is the first report of parasitism in this host and culture.KEY WORDS: Insecta, egg parasitoid, lepidopteran defoliator RESUMO -Visando averiguar a presença de parasitóides do gênero Trichogramma, para utilização no controle biológico de pragas na cultura do feijão-vagem, foram coletadas posturas de Urbanus proteus (L.) que apresentavam ovos com características de parasitismo (ovos escuros). Os ovos foram encaminhados ao laboratório, onde se observou 44,9% de parasitismo. Constatou-se a viabilidade de 96.3%, com a média de 6,6 indivíduos por ovo e razão sexual de 0,93. Espécimes machos foram identificados, mostrando tratar-se de Trichogramma bruni Nagaraja, espécie que até então não havia sido descrita nesse hospedeiro e cultura. PALAVRAS-CHAVE: Insecta, parasitóide de ovos, desfolhadorO feijão-vagem é uma fabácea da mesma espécie do feijão comum, Phaseolus vulgaris L., com a mesmas características, em sua maioria, e é cultivado durante todo o ano, em regiões de clima tropical e baixa altitude. É uma das olerícolas de maior comercialização, com a maior parte da produção consumida in natura (Filgueira 2003), o que torna indispensável oferecer um produto limpo, livre de pragas e resíduos de agrotóxicos.Diversas pragas podem ocorrer no feijão-vagem e, dentre elas, a lagarta cabeça-de-fósforo, Urbanus proteus (L.), tem sido registrada em vários estados brasileiros, causando danos em várias fabáceas de importância econômica. Alimenta-se do limbo foliar com voracidade, podendo causar desfolha total da planta e até danificar as hastes mais finas (Nava & Parra 2002).Como essa praga em feijão-vagem causa danos através de surtos, seu controle tem sido realizado exclusivamente com inseticidas, muitas vezes indiscriminadamente, o que eleva o custo de produção e leva ao aumento do desequilíbrio do agroecossistema.Como forma alternativa de manejo de pragas, visando reduzir o uso de agrotóxicos, tem-se os inimigos naturais, como os parasitóides de ovos do gênero Trichogramma. Estes estão entre os mais importantes e utilizados, principalmente, por estarem presentes em quase todas as regiões biogeográficas do mundo, e serem produzidos escala massal e econômica (Haji et al.

The Neotropical genus Urbanus (Hübner) (Lepidoptera: Hesperiidae) contains around 34 described species, and is widely distributed from the extreme southern United States to Argentina. Here, we describe the larval morphology and behavior of Urbanus esmeraldus (Hübner)(Hesperiidae) in Urera baccifera (Urticaceae), a plant producing food rewards and fleshy fruits that attract ants (including predacious species) in a Brazilian forest. Larvae pass through five instars and construct two kinds of leaf shelters. Experiments with ejected fecal pellets showed that these can serve as cues to ground—dwelling ants that climb onto host plants and potentially attack the larvae. Manipulation with pellets placed at different distances suggests that ejection behavior decreases larval vulnerability to ant predation. Larval preference for mature leaves may be related with increased predation risk at ant—visited young leaves. The study shows that a combination of natural history and experimental data can help understand the life history of a butterfly using a plant with high predation risk.
