This study investigates the effects of tillage and fertilization on changes of soil organic carbon (SOC) stock in a 46-year long-term field experiment in Thailand. The economic cropping system was maize-mung bean rotation. The experiment treatments included plots with tillage, no tillage, chemical fertilizer, organic amendment, and combination of chemical and organic fertilizer. No-tillage significantly increased soil aggregate stability [water-stable aggregates (WSA), mean weight diameter, and geometric mean diameter]. However, only rice straw applications enhanced WSA. SOC stocks of the same soil mass ranged from 21.7 to 40.1 Mg C ha-1. The highest SOC stock (40.1 Mg C ha-1) and sequestration rate (0.40 Mg C ha-1 year-1) were observed in no-tillage plots with cow dung and chemical fertilizer. These findings underscore the significant potential of integrated practices involving no-tillage and organic amendments to improve soil structure and carbon sequestration in tropical agricultural systems.

This species was originally described based only on females from Misiones Province, Argentina. Comparison of the holotype female to a series of recently collected males and females from northern Argentina (Corrientes) revealed that A. cyrtobrachium Cheng is a junior synonym of A. typicus. Males matching Cheng’s (1980) description and illustrations of A. cyrtobrachium were collected in association with females having the distinctive shape and markings of the pregenital abdominal segment identical to that of the female holotype of A. typicus in the U.S. National Museum. Agudus cyrtobrachium was described based on three male specimens from Paraguay.

ARGENTINA: Loreto, Misiones, XII-10-1931, AA Ogloblin (6 males, 2 females, 1 sex undet.; one of these males with label USNMENT02110683). Same locality, XII-12-1931 (1 male); XII-1-1931 (1 male); XII-4-1931 / USNMENT02110493 (1 male); XII-18-1931 (1 male); XII-6-1931 / allotype (1 female) [all USNM].Notes. This species was described based on three specimens from Misiones Province, Argentina. It differs from other red-striped species of Agudus in having the scutellum almost completely red and the aedeagus with three pairs of apical processes. No recently collected specimens of this species have been found, despite recent sampling in grasslands throughout northern Argentina, suggesting that this species is now extremely rare or extinct (see above notes under A. longiceps).

E of Asuncion, 16 Aug 1980, D.C. Lowrie (1 male) / Agudus sexmaculatus Linnavuori, Det. JN Zahniser 2026 / USNMENT02110346 [USNM].Notes. This species is recorded from Argentina and Paraguay. The female is here described and illustrated for the first time. Linnavuori (1959) indicated that the type specimen (a male) and one female paratype were deposited at USNM and one specimen (sex not stated) was retained in his personal collection. Upon initial examination of the USNM type collection, the type was not found. However, one male specimen in the main collection in a unit tray identified as A. sexmaculatus was apparently examined by Linnavuori and the genitalia match Linnavuori’s figures. His examination of that specimen is deduced by the preparation of the genitalia which are dismembered and glued to a card, a procedure that was typical of Linnavuori for specimens he examined and illustrated, including types, and was not a technique known to be used by other New World leafhopper workers. Here, the genitalia on the card were imaged and then the parts were lifted off by soaking in water and are now stored in glycerine in a genitalia vial. This male has the locality data (Loreto, Misiones; coll. AA Ogloblin) given by Linnavuori, but the date (XI-25-1931) differs slightly from what was stated for all three specimens (XII-10-1931) in Linnavuori’s publication. Despite this discrepancy, this male is interpreted here as the holotype. There are many other leafhopper specimens at the USNM from the same locality with different dates of collection, and it is possible that Linnavuori incorrectly transcribed the collection dates. The female stated by Linnavuori (1959) to be deposited at USNM was not found, although it is possible the specimen listed in Material Examined (above) with the abdomen missing is this female, and the collection date of that specimen (XII-10-1931) matches that reported by Linnavuori. Linnavuori (1959) stated that males of this species are 5 to 6 mm in length, and that the female he examined was 7.2 mm. However, these measurements seem to be inaccurate. The male type specimen is 4.5 mm, measured from apex of head to forewing apex (forewings surpass the abdomen in this species). The other three males at USNM are 4.5, 5.0, and 5.0 mm long. The specimen with missing abdomen is 5.2 mm.

Agudus longiceps (Berg, 1879)Platymetopius longiceps Berg, 1879: 267Notes. This species, originally described from Buenos Aires, Argentina, was redescribed and illustrated by Linnavuori (1959) based on the type and an additional male specimen from a locality near Buenos Aires. It is considerably larger than other known species of the genus (males 9.5 mm long) and also differs in having a darkly pigmented ventral tooth on the pygofer lobe and the apical processes of the aedeagus sharply bent laterad near the apex. The female remains unknown. Recent collecting in pampas grasslands near Buenos Aires has failed to yield additional specimens of this species. Given the extensive urbanization and agricultural intensification in the Buenos Aires region since the species was originally collected and described, it appears that this species is now either extremely rare or extinct.
