Keywords: caterpillar, developmental parameter, egg, pupae, southern armyworm Since the beginning of the last century, S. The polyphagy of this species led to important studies on the selection and use of various host plants by polyphagous insects e.
A large number of records are from crop pest survey studies e. Furthermore, studies by Soo Hoo and Fraenkel a , b reveal that this species tolerates, and grows well on, several species on which their larvae were not collected in nature. The large number of references of this species indicates the importance of this insect to different crops such as alfalfa, bean, beet, cabbage, cassava, collard, cotton, onion, peanuts, quinoa, soybean, tobacco, tomato, sweet potato, sunflower, and truck crops, in various locations throughout American continent e.
Beyond its great voracity and reproductive capacity e.
Considering the importance of S. We employ and validate a methodology that incorporated detail setting not made by others studies, e.
Additionally, this study aimed to gather and organize information relating to host plants, emphasizing South American records. Identification was accomplished by comparing larvae and adults with descriptions in Pogue All the experiments were performed, with one daily observation indicated at p. Louis, MO lined with filter paper moistened with distilled water, where it remained until the eclosion of the larvae.
We evaluated the feasibility fertility and the embryonic period, in days, of 28 egg masses 2, eggs taken randomly from five couples, including the first and last ovipositions. The bottom part of the container was closed with a Petri dish Larval Stage Soon after hatching, larvae from the second-laid egg mass of a single female were individually placed in properly identified ml plastic cups, covered with a transparent plastic cap.
Daily observations were made to verify the survival and development of the larva with the removal of the head capsule. During these observations, the diet and the cotton were replaced, to maintain humidity, always being careful to not interfere and to touch the larva as little as possible.
The head capsules were individually stored, by larvae, in microcentrifuge tubes, for posterior measurement.

In some cases, the change of instar was noticed through the development of the larva, but the capsule was not found, most likely because it had been eaten by the larva, which is relatively common among insects.
In these cases, the date of ecdysis was recorded, and the size was then compared with the other larvae to confirm ecdysis, and the corresponding duration of each stage. When the larvae reached the prepupal period, characterized by a decrease in size and the interruption of feeding, the diet and the cotton swab were removed.
Thereafter, expanded vermiculite, moistened with distilled water, was added to each cup to a height of 0. We maintained the identification number from the larval to the pupal stage to record the number of instars, the survival, and the individual duration of each stadia and prepupal period, taking into account the sex of each larva. It also allowed us to evaluate growth as a function of the number of larval instars. To record the average size of each larval instar of S.
Most of the larvae developed through six instars, of which randomly selected 15 specimens that originate females and males to measure the head capsules. Abstract New distributional data are reported on the rare phanaeine dung beetle, Oxysternon pteroderum Nevinson, , based on five specimens recently collected between and Before the present study, Oxysternun pteroderum had been reported solely from the super-moist Atlantic coastal forests of southeastern Brazil.
We now believe that the distribution of Oxysternun pteroderum follows the riparian areas of large rivers connected to the super-moist forest ecosystem. This speciesis isolated taxonomically and geographically from the other members of the genus and is not easily confused with any congener.
The form of the male pronotum and absence in both sexes of tubercles and other protuberances on the head are unique in the genus. Arnaud, , placed Oxysternun pteroderum in a subgenus of its own - Pteroxysternon Arnaud, However, regardless of being in the same subgenus or not, those species included by Edmonds in Mioxysternon Edmonds, appear to be more closely related between them than to species in the nominotypical subgenus. The purpose of this paper is to present new data on recently post collected specimens known to us.
We are aware of five specimens from different locations in three different states, collected between and We comment on these below. The collection method is unknown. Ipatinga is located on the margin of the Rio Doce, the most important river in this region.
Thus, the gallery forests that follow the rivers in this basin have an important role connecting Atlantic forest in the coastal lowlands with other areas of Atlantic forest at higher altitudes inland. Ide legs. Linhares is at the mouth of the Rio Doce mentioned above, and lowland evergreen forest is continuous between this and the site previously mentioned.

This road was bordered on one side about 5 m from the road with secondary Atlantic forest Ombrophilous forest , that was very dry and low in height.Log in. The coexistence of E. Ide legs. Individually or combined, mites can reach high population levels on papaya leaves. World Crop Pests Series Vol. This speciesis isolated taxonomically and geographically from the other members of the genus and is not easily confused with any congener.
