13. Elbella luteizona (Mabille, 1877) (Lepidoptera, Hesperiidae: Pyrginae) in Brazilian Cerrado: larval morphology, diet, and shelter architecture
Abstract This study examined temporal variation in the abundance of immature stages of Elbella luteizona (Hesperiidae) and describes the morphology and behavior of the larvae on their host plants, Byrsonima coccolobifolia and Myrsine guianensis. Five hundred sixty-eight 10 m diameter plots were searched for caterpillars in the Brazilian Cerrado over a period

14. SPRAY DRIFT AND CATERPILLAR AND STINK BUG CONTROL FROM AERIAL APPLICATIONS WITH ELECTROSTATIC CHARGE AND ATOMIZER ON SOYBEAN CROP
ABSTRACT: The use of aerial application with electrostatic charge is an alternative to improve the quality of insecticide applications in soybean crop. The objective of this study was to evaluate the drift and chemical control of the caterpillar and stink bug complex promoted by aerial applications of insecticide in the soybean crop, using electrostatic spra

15. Annona crassiflora Mart. (Annonaceae): effect of crude extract of seeds on larvae of soybean looper Chrysodeixis includens (Lepidoptera: Noctuidae)
ABSTRACT The effect of a crude extract of Annona crassiflora was evaluated on larvae of the soybean looper, Chrysodeixis includens (Lepidoptera: Noctuidae) in different stages of larval development. The extract was prepared with seeds of A. crassiflora fruits collected in the state of Mato Grosso, Brazil. The extract was diluted in water and solubilizer agen

16. SPRAY DRIFT AND PEST CONTROL FROM AERIAL APPLICATIONS ON SOYBEANS
ABSTRACT Pesticide drift is an issue in modern farming, mainly for crops under constant spraying as soybeans. This study aimed at assessing drift and pest control for aerial applications in soybean crops. Hydraulic nozzles and rotary atomizers, regulated to a wide spectrum of droplet sizes, sprayed thiamethoxam plus lambda-cyhalothrin using an agricultural a

17. Hemostatic disorders induced by skin contact with Lonomia obliqua (Lepidoptera, Saturniidae) caterpillars
ABSTRACT Patients envenomed by Lonomia sp caterpillars initially experience a mild burning pain, headache, nausea, vomiting, and skin and mucosal hemorrhages. Some patients can rapidly progress to a severe coagulopathy that presents as visceral or intracerebral hemorrhaging. We studied the hemostatic alterations that occurred in 14 patients who were envenome

18. Bicarpellate gynoecium in two species of Senna (Fabaceae, Caesalpinioidae, Cassiinae)
ABSTRACT Flowers of species of Senna are very morphologically diverse, however, nothing has been reported regarding variation in the presence of a unicarpellate gynoecium, which is characteristic of the group. This study reports the occurrence of a bicarpellate gynoecium in two enantiostylous species of Senna in an area of dry forest (Caatinga) in NE Brazil.

19. Biology of the immature stages of Strymon crambusa (Lycaenidae, Theclinae) on Oxalidaceae
ABSTRACT We document the biology and morphology of the egg, caterpillar, and pupa of Strymon crambusa (Hewitson, 1874), a Neotropical Eumaeini. In the Cerrado, the caterpillar feeds on the inflorescences and leaves of Oxalis L. S. crambusa has four larval instars, all of which are illustrated. The density of caterpillars on plants is higher than that recorde

20. Timeline and geographical distribution of Helicoverpa armigera (Hübner) (Lepidoptera, Noctuidae: Heliothinae) in Brazil
ABSTRACT This study presents registers of Helicoverpa armigera (Hübner) occurrence to assess its spatial and temporal distribution in Brazil. We used data from collections, especially from the Southern Region, systematic collections in Rio Grande do Sul, occasional collections of caterpillars and adults in different regions of Brazil, as well as literature

21. Epidemiology of envenomations by terrestrial venomous animals in Brazil based on case reporting: from obvious facts to contingencies
Abstract Background: Envenomation remains a neglected public health issue in most tropical countries. A better understanding of the epidemiology of bites and stings by venomous animals should facilitate their prevention and management. This study aimed to explore the benefits that could be derived from the compulsory notif

22. Resistencia al desgaste de materiales de las orugas de tractores después del proceso de recuperación
This study proposes an alternative for the recovery of the crawler tractor bulldozer worn by the abrasive effect of the soil. To this end, deals with a comparative analysis between the wear resistance of an original track like two caterpillars, recovered by different processes. The first recovery process uses the application of a hairpiece in the region of w

23. Accident involving a 2-year-old child and Lonomia obliqua venom: clinical and coagulation abnormalities
Poisons of caterpillars have different effects on inflammatory and coagulation systems. This is a case report of a 2-year-old child that accidentally came in contact with several caterpillars of the species Lonomia obliqua. At first, the patient's exams presented abnormal coagulation and decreased fibrinogen, but the patient did not evolve to active bleeding

Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes. The shrub Dalea pennellii var. chilensis (Fabaceae) is reported for the first time as a host plant for three Neotropical Polyommatini (Lepidoptera, Lycaenidae, Polyommatinae): Hemiargus ramon (Dognin, 1887), Leptotes trig
