“…Essa característica é comum para larvas de melolontídeos (Fig 2) (Teetes et al 1976, Oliveira et al 1996, Silva & Grützmacher 1996, Salvadori 2000. A razão de crescimento média da cápsula cefálica de L. suturalis foi de 1,58 mm (Tabela 1), evidenciando a mudança de ínstar do inseto, conforme estabelecido pela regra proposta por Dyar para lagartas, mas também utilizada para outras ordens de insetos (Parra & Haddad 1989).…”

Biological Notes and Behavior of Liogenys suturalis Blanchard (Coleoptera: Melolonthidae) in Mato Grosso do Sul State, BrazilABSTRACT -Liogenys suturalis Blanchard is one of the main soil pests associated to corn, wheat and oat crops in the Southern Mato Grosso do Sul State. This work aimed to investigate the bioecological and behavioral aspects of this pest. The study was carried out in several municipalities of Mato Grosso do Sul State under fi eld and laboratory conditions from August 2004 to December 2006. In the laboratory, we studied the incubation period and egg viability, the number of instars, and pupal and adult sexrelated traits. The insect distribution was determined yearly, as well as the period of insect fl ying and some behavioral aspects during mating. Egg viability averaged 81.7%, with an incubation period of 22.8 ± 4.32 days. Liogenys suturalis took the whole year to complete its life cycle, developing through three different instars. The highest larval feeding activity and development occurred in February and June, and adult fl ight activities were between the second fortnight of September and December. Sex dimorphism was observed in both pupae and adults. Flights were concentrated from 7:00 to 8:00 PM. The average time for mating was 9.82 min. The observed adult sex ratio was 0.63.

“…There is no common name for this species. In Texas, the larvae have been reported feeding in rangeland pasture, ornamental turf, sugarcane, grain sorghum, cotton, and wheat, as well as corn, parsley, and cabbage (Reinhard 1940;Teetes 1973Teetes , 1976Huffman et al 1976;Huffman and Harding 1980). P. crinita larvae are also serious pests in Mexico (Rodriguez-del-Bosque 1984, 1995.…”

The female-produced sex pheromone of Phyllophaga crinita (Burmeister) (Coleoptera: Scarabaeidae: Melolonthinae; the adult has no common name) is identified as methyl 2-(methylthio)benzoate. This is the first identification of a sulfur-containing, long-distance, female-produced sex attractant from any insect taxa. The root-feeding larvae of this species are serious pests in many crops in Texas and Mexico. In field tests, many P. crinita males were captured in traps baited with the authentic compound. Interestingly, a heteroatom analog, methyl 2-methoxybenzoate, also captured P. crinita males, but only at a dose 10,000 times higher than the lowest tested dose of the authentic pheromone.

“…Interestingly, on the second release date, although approximately 82% of females were released, only males were recaptured, con rming that males were more active on this date, perhaps in search of mating partners. Studies of P. crinita (Burmeister) have shown greater activity of males than females, which are less attracted to light traps and y short distances to oviposits (Teetes et al 1976;Stone 1986). We observed that females of P. capillata, however, are able to y at least 150 m, a distance much greater than that reached by females of a congener, P. cuyabana, which in Brazil reached 20 m (Oliveira and Garcia 2003).…”

Mark-release-recapture studies have been used to evaluate the dispersal ability of different insect species.In the eld, we evaluated the dispersal ability of the soil pest species Phyllophaga capillata (Blanchard) (Coleoptera: Melolonthidae) in soybean (Glycine max L.) crop, and the ight activity of this species under controlled conditions. Field studies were conducted on a soybean seed production farm in Planaltina/DF, Brazil. On four dates, adults of P. capillata were collected, sexed, marked and released in a soybean plot (~ 230 ha). Twelve light traps were set in three concentric circles, with four traps each, at distances of 50, 150 and 250 m from the point of adult release. Under controlled conditions, groups of adults (males and females) were separated into pots containing soil, and the ight ability of the specimens was evaluated daily for 72 h. The average recapture rate of adults was 1.93% for the four collection dates. The highest recapture rate was observed at a distance of 50 m, at the beginning and middle of the swarming period, and at 250 m at the end of the swarm. Males, in general, were more active than females and reached the greatest distance of displacement (250 m). Most specimens (69.5% of males and 52.9% of females) were prone to leave the ground on the three consecutive days of the study. These results provide insights for understanding the dispersal patterns of this pest species in agricultural landscapes.
