Forests are essential for human wellbeing since they provide multiple goods and services (of regulation, provision, cultural) that benefit human health. Insect pollinators represent one of the most important components of forest diversity because they have a significant role both in the plant species biodiversity conservation and agricultural production. In a multiannual monitoring of Meliponini wild colonies in a Dry Chaco forest, we have used a simple method to find colonies inside trees, even when conditions prevented foraging-activity of bees (cold, extreme heat). We briefly describe this method here and discuss its utility for ecologists and peasant communities.

Last instar larvae of the variegated mud-loving beetle Heterocerus similis Grouvelle are described and illustrated in detail. Comparative notes with earlier instars are also included. Based on the width of the head capsule and the prothorax four different instars were identified; considering that heterocerids show five larval instars, the four instars identified probably correspond to the last four. Larval length was not useful to recognize among different larval stages. The larva of H. similis is compared to that of H. freudei (Pacheco), the only other described South American heterocerid larva.

Toxicity of four pesticides in ecosystem services of terrestrial arthropofauna in cocoa cultivation was evaluated. Cypermethrin (T1), carbofuran (T2), copper oxychloride (T3) and chlorpyrifos (T4) were applied in a cocoa farm in San Martín, Peru. Forty pitfall traps were placed for each treatment to capture terrestrial arthropofauna in four evaluations. It is concluded that the families that presented the greatest abundance of individuals were Formicidae, Entomobryidae and Poduridae. For the global evaluation, significant differences were found in the predators for the specific richness index, being T3 the one that presented the lowest numbers; while for the Margalef index, the lowest value was T3. For the analysis by evaluations, significant differences were found in the detritivores during the second evaluation for the number of individuals, with T4 being the lowest number. Significant differences were also found in the predators during the first evaluation in the Margalef index, with the lowest value being observed in T4. The trophic guild that allowed the most efficient evaluation of the toxicity were the predators, T1 is the most compatible pesticide with the terrestrial arthropods associated with cocoa cultivation, and the alpha diversity indices showed significant differences between the applied pesticides.

Understanding the seasonal prevalence and biological parameters of mosquito Aedes albopictus (Skuse) are indispensable for population estimates, efficient vector control and dengue prevention tactics. The sampling of Ae. albopictus was completed through the collection of eggs, larvae, pupae and adults throughout the study seasons by use of nets and ovitraps at least once a week. Occurrence of Ae. albopictus was distinguished heterogeneously and populations were observed maximum in October post-monsoon season. The populations increased progressively from January-May and sharply deteriorated in June-July and September-November months revealing the highest breeding. However, the lowest density was observed during December-February. Growth of Ae. albopictus evaluated under standardized laboratory conditions with the provision of Balb/C mice as blood meal to adult mosquitoes, exhibited eggs hatching, and first, second, third and fourth instar larvae development in 3, 1.3, 1.2, 1.7 and 2.8 days, respectively. Nevertheless, pupation development, adult emergence, total life duration from egg hatching to adult emergence, male and female life spans persisted for 7, 3, 20, 25 and 30 days, respectively. Aedes albopictus accounted for 1% density of other mosquito genera collected (Culex and Anopheles), while, Aedes aegypti (L) was 3% abundant and indicated that both Aedes species had coexistence.

The insecticidal and repellent activities of methanolic extracts of Ruta chalepensis L. (Rutaceae: Sapindales), Rhazya stricta Decne (Apocynaceae: Gentianales), Heliotropium bacciferum Forssk (Boraginales: Boraginaceae), Salvadora persica L. (Salvadoraceae: Brassicales), and Moringa oleifera L. (Moringaceae: Brassicales) were investigated against the saw-toothed grain beetle Oryzaephilus surinamensis L. (Coleoptera: Silvanidae). Results demonstrated that all these plant extracts had variable toxicity against the beetle. The effectiveness of the tested plant extracts was shown by increasing the used concentrations. The methanolic extract from R. stricta performed the best and was able to cause 93.3% and 89.2% mortality for the adult and larval stage of O. surinamensis, respectively, at 500 ppm after six days of plant extract treatment. The tested extract of S. persica at 500 ppm caused 80.8% and 82.5% mortality on larvae and adults of O. surinamensis after six-day of treatment. On the other hand, repellent effects of extracts of R. stricta, S. persica, and R. chalepensis at 500 ppm were recorded, with higher values of 91.7%, 83.3%, and 78%, respectively, against the adults of O. surinamensis, which were under 500 ppm. These extracts especially from R. stricta, S. spinosa, and R. chalepensis could be useful to prevent damages and store grain production losses for O. surinamensis.

The efficacy of most synthetic insecticides has been compromised against Chilo partellus (Swinhoe) due to its cryptic feeding behavior, hence there is a dire need to find other eco-friendly effective management approaches to combat this notorious pest. The susceptibility of 2nd and 4th larval instars of C. partellus was assessed against Bacillus thuringiensis var. kurstaki (Bt-k) (Berliner) and Metarhizium anisopliae (Mechnikov) under controlled conditions. The larvae were treated with individual or combined treatments of a single dose rate of B. thuringiensis (Bt: 0.75 µg/g) and three conidial concentrations (1x104, 1x106 and 1x108 conidia/ml) of M. anisopliae. The individual and combined application of both entomopathogens significantly affected the mortality, pupation, adult emergence, mycosis and sporulation of both larval instars of C. partellus. Maximum larval mortality (2nd instar: 94.63% and 4th instar: 91.43%) was recorded in combined applications of M. anisopliae (1x108 conidia/ml) and B. thuringiensis (0.75 µg/g). The same integrated treatment also caused significant declines in pupation (2nd: 0.00% and 4th: 6.66%) and adult emergence (2nd: 0.00% and 4th: 0.00%) of C. partellus as compared to rest of the experimental treatments. Moreover, a significantly higher rate of mycosis and sporulation were recorded in both larval instars (2nd: 88.52% and 143.96 conidia/ml) and (4th: 82.04% and 131.85 conidia/ml), when exposed to lower individual concentration of M. anisopliae (1×104 conidia/ml). The current results suggest that integrated application of M. anisopliae and B. thuringiensis could be a sustainable management tool for C. partellus in maize crop.
