Occurrence of Dinarmus basalis in Callosobruchus analis in stored soybean in São Paulo, Brazil

Abstract

Callosobruchus analis (F.) is considered an important pest in several countries in Africa, Asia and Oceania. It has been observed infesting seeds belonging to 15 Leguminosae genera, including peanut, bean, chickpea, pea, cowpea, and soybean. One of its main natural enemies is the parasitoid Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae), whose control efficiency has already been demonstrated in several studies. This paper records the occurrence of C. analis and its parasitoid, D. basalis, in stored soybean of the state of São Paulo, Brazil.

Synthesis and pesticidal activity of new N-alkyl-N-[1-(2-hydroxyphenyl) ethyl]amines

“…Absorption at 3316 and 1588 cm −1 in its IR spectrum, showed the presence of C-NH group in the molecule. This was supported by a signal at δ 44.5 for C-1 carbon attached to nitrogen in its 13 C NMR spectrum. This was also confirmed by the absence of a peak at δ 164.8, characteristic of C=N in its 13 C NMR spectrum.…”

“…This was supported by a signal at δ 44.5 for C-1 carbon attached to nitrogen in its 13 C NMR spectrum. This was also confirmed by the absence of a peak at δ 164.8, characteristic of C=N in its 13 C NMR spectrum. The 1 H NMR of 1 showed three signals in aromatic region placed at δ 6.77-6.83 (2H, m), 6.95 (1H, dd, J = 7.6 & 1.6 Hz) and 7.12-7.17 (1H, m) for H-3 &H-5, H-4 and H6, respectively.…”

“…It has been observed that seeds belonging to 15 Leguminosae genera, including green gram peanut, bean, chickpea, pea, cowpea, and soybean were affected by this insect. [13] Our group has been actively involved in the development of heterocyclic molecules for their potential use in pest control. [14,15] In view of the importance of heterocyclic compounds in general, and amines in particular, we envisaged upon the synthesis of new heterocyclic amines and exploited their potential in pest control, namely, fungicidal and insecticidal activity.…”

Paracrias pluteus (Hymenoptera, Eulophidae) in Brazil: new distribution and host records, and with a new host group for Paracrias

“…Bruchines ( Coleoptera : Chrysomelidae : Bruchinae ) are considered pests of seeds of native and cultivated legumes in Latin America, causing damage to several economically important agricultural species ( Rojas-Rousse et al 2007 ) such as Glycine max ( Costa et al 2007 ), Phaseolus coccineus , Phaseolus vulgaris , Phaseolus lunatus ( Hansson et al 2004 , Bonet 2008 ), Vigna radiata ( Somta et al 2008 ), Vigna unguiculata ( Aebi et al 2008 ), and tree species such as Enterolobium contortisiliquum ( Morandini and De Viana 2009 ), Melanoxylon brauna ( Santos et al 1991 ), Mimosa bimucronata ( Silva et al 2007 ), Sclerolobium sp. ( Santos et al 1997 ) and Senna multijuga ( Sari and Ribeiro-Costa 2005 ).…”
