Through the physical review of the Hymenoptera collection of the National Museum of Costa Rica and 53 articles associated with the description of species, we found a total of 4218 paratype specimens, representing 17 families, 41 subfamilies, 47 tribes and 143 genera. Some of them belonging to the genus Heterospilus were damaged during a return of material by mail, and others have genetic sequencing available for research. The possibility that many other paratypes are found in other collections i...

The efficacy and dose-response, residual effect, and effect on the fecundity of neem formulations on cabbage aphid Brevicoryne brassicae applied systemically through root tissues of Brussels sprouts ( Brassica oleracea), were studied in the greenhouse. Two formulations were tested; NeemAzal granules containing 7% azadirachtin (AZA), at 75, 150, 225 and 300 mg per kilogram of the substrate and a water-based formulation, NeemAzal-T (1% AZA) at 1, 1.5, 2 and 2.5 ml/kg of substrate. The...

Field and laboratory experiments were conducted to study the residues and dis-sipation of Fluopyram, a succinate dehydrogenase inhibitor (SDHI) and tebu-conazole, demethylation inhibitor (DMI) used for the control of powdery mil-dew and Anthracnose diseases in grape. Residues of fluopyram dissipated with a half life of 4.04 and 5.18 days, at recommended and double dose, respectively. For tebuconazole, the half life values recorded ...

In this study, the biological parameters of two B. atrolineatus strains
originated from two different agro-ecological areas of Niger are examined. The
analysis of the adult lifetime showed that B. atrolineatus strain of the
Sahelo-Sudanese area lived longer (7.58 ± 2.19 days) than that of the Sahelian
area (7.44 ± 1.39 days). Furthermore, males lived longer than females
regardless of the strain origin. The egg laying activity showed that the eggs
laid number was not s...

To evaluate the growth and feeding
inhibitory activities leaves extract of Tragia
involucrata tested against third instar larvae of Achaea janata and Pericallia
ricini. Feeding inhibition, larvicidal and growth inhibitory activities
were tested with different solvent extracts of hexane, chloroform and ethyl
acetate. Chloroform extracts showed promising feeding deterrent and larvicidal
acti ...
