Pest damage due to coffee berry borer and shot hole borer in coffee plantations in Regional Coffee Research Station, Chundale and data on weather parameters were recorded during 1977 to 2007 (30 years). These long- term data on the pest damage and weather parameters were utilized to study the influence of weather variables on coffee berry and shot hole borer incidence with a view to develop weather based forewarning models for coffee berry borer and shot hole borer damage in Wayanad. The damage of coffee berry borer (CBB) was observed to be significant during January to March while the damage of shot hole borer (SHB) was spread during January to April and October to December. Highest percent damage of coffee berry borer and shot hole borer was observed during first fortnight of January. Maximum damage due to coffee berry borer was observed during 1982 and maximum damage due to shot hole borer was observed in 1994. Maximum temperature recorded during the first fortnight of January is predominant weather variable determining infestation of shot hole borer during first fortnight of January. Harvest and budding stages of the crop suffered heavy incidence of coffee berry borer and shot hole borer, respectively.

This paper aims to study the long-term trends in different weather parameters, i.e., temperature, rainfall, rainy days, sunshine hours, evaporation, relative humidity and temperature over Lower Shivalik foothills of Punjab. The daily weather data of about 35 years from agrometeorological observatory of Regional Research Station Ballowal Saunkhri representing Lower Shivalik foothills had been used for trend analysis for kharif (May - October), rabi (November - April), winter (January - February), pre-monsoon (March - May), monsoon (June - September) and post monsoon (October - December) season. The linear regression method has been used to estimate the magnitude of change per year and its coefficient of determination, whose statistical significance was checked by the F test. The annual maximum temperature, morning and evening relative humidity has increased whereas rainfall, evaporation sunshine hours and wind speed has decreased significantly at this region. No significant change in annual minimum temperature and diurnal range has been observed. Monthly maximum temperature revealed significant increase except January, June and December, whereas, monthly minimum temperature increased significantly for February, March and October and decreased for June. Among different seasons, maximum temperature increased significantly for all seasons except winter season, whereas, minimum temperature increased significantly for kharif and post monsoon season only. The evaporation, sunshine hours and wind speed have also decreased and relative humidity decreased significantly at this region. Significant reduction in kharif, monsoon and post monsoon rainfall has been observed at Lower Shivalik foothills. As the region lacks assured irrigation facilities so decreasing rainfall and change in the other weather parameters will have profound effects on the agriculture in this region so there is need to develop climate resilient agricultural technologies.

Traps lured with semiochemical have been proposed to manage the coffee berry borer, coffee planting is however made under several environmental conditions that may affect the efficacy of traps. Several trap designs and variations were proposed and, therefore, a series of field experiments was carried out to capture coffee berry bores in traps disposed in a low density coffee plantations in the Northern part of the State of Paraná, Brazil. Traps were composed of plastic bottles (2 L) with a window (13 × 18 cm). Ethanol (E), Methanol (M) and coffee oil alone did not improve the capture when transparent traps with a 2 mm hole in the vial dispenser were used; traps lured with E : M mixtures (1:1, 1:2, 1:3) caught similar and higher number of insects than the control. There was synergism with the mixing of E and M; the addition of coffee oil to the mixtures did not improve the capture. Trap lured with E : M (1:1) mixtures at 342, 400, 428 and 710 mg caught similar numbers of insects. Transparent green trap, transparent trap and red trap lured with 642 mg day-1 of the E + M (1:1) mixture caught similar numbers of insects. Interaction between colors (transparent green, transparent and red) and semiochemical release rates (540, 720 and 1100 mg day-1) was observed. Transparent green trap, when lured with 720 mg day-1 of the 1 : 1 E : M mixture caught 2.3 and 4.4 times more insects than 540 and 1100 mg day-1; and caught 3.2 times more insects than transparent and red trap at the same release rates.

Term Data

In monitoring studies of recent years, global warming is reported. This is a significant problem for dairy farming in much of Europe, especially in the central and southern regions, as reported by numerous studies. Dairy cattle highly productive are extremely sensitive to hot temperatures; their consequence is health problems, a significant reduction in milk yield and milk quality. Unfortunately, heat stress remains an unrecognized problem for domestic cattle breeding, although the financial losses from its harmful influence in European are quite substantial. The aim of our work was to study the effect of high temperatures on milk yield of cows of Ukrainian Schwitz on one of the complexes of high-tech milk production. At the beginning of the research, we decided to test the hypothesis of increasing hot air temperatures in the warm period of the year compared with the long-term data. Then we studied how the milk of Schwitz breed varies during the hot season, depending on the magnitude of the maximum temperature values. According to the results of the study, it can be noted that the air temperature during the warm period of 2017 tended to increase (+0.6 °С) in comparison with the long-term data. In August, the air temperature significantly exceeded the long-term data by +3 °C (td = 2.89, P < 0.05). The relationship between the temperature and milk yield of cows is revealed by an average degree of reliability (r = -0.45, P < 0.05). Compared with the most favorable external conditions in May, the cows' milk yield decreased in June by 3.0%, the yield of milk fat by 5.2%, the milk protein content by 3.4% (P < 0.001). In July and August, the cows' milk yield decreased by 4.6 and 5.5% (P < 0.001), the yield of milk fat decreased by 3.1 and 7.3% (P < 0.01–0.001), the yield of milk protein 3.4 and 5.7% (P < 0.001). Thus, high temperatures during the summer period contributed to a decrease in milk yield and the main components of milk of the Ukrainian Schwitz, which can lead to tangible financial losses.

A broca-do-café, Hypothenemus hampei (Ferrari) é responsável por grandes prejuízos em plantios de café, causando perdas de produtividade aos cafeicultores e danos quantitativos e qualitativos aos grãos. O controle biológico da praga tem sido principalmente à base de fungos entomopatogênicos. Em Rondônia, Brasil, as informações acerca dos parasitoides de H. hampei são escassas. O parasitoide Cephalonomia stephanoderis Betrem é um inimigo natural da broca do café e já é utilizado como agente de controle biológico em países da África e da América Latina. Constatou-se a presença desse parasitoide em cafezais de Rondônia. O objetivo do presente estudo foi investigar os níveis de ocorrência e parasitismo do parasitóide em uma plantação de café no município de Ouro Preto D’Oeste, Estado de Rondônia. Foram analisados semanalmente frutos de café coletados diretamente das plantas e caídos sobre o solo, de janeiro a dezembro de 2004. Observou-se a ocorrência do parasitoide durante os meses de maior infestação da praga. Durante o período estudado, a taxa de parasitismo nos diferentes microambientes variou de 2 a 24%. Parasitism in the Population of the Coffee Berry Borer Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) by the Parasitoid Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidae) Abstract. The coffee berry borer, Hypothenemus hampei (Ferrari) attacks coffee plantations, greatly decreasing the production of coffee plants, causing quantitative and qualitative damage to the grains. Biological control of this pest has focused mostly on entomopathogenic fungi. In the state of Rondonia, studies on parasitism levels of the parasitoids of H. hampei are scarce. The parasitoid Cephalonomia stephanoderis Betrem is a natural enemy of the coffee berry borer and is already used as an agent of biological control in countries of Africa and Latin America. The objective of the present study was to investigate the occurrence and parasitism levels of the parasitoid in a coffee plantation in the municipality of Ouro Preto D’Oeste, State of Rondonia. Coffee beans collected directly from the plants and on the ground were analyzed weekly from January to December 2004. Parasitoid occurred in months of the highest pest infestation. During the studied period, parasitism rate in different microenvironments ranged from 2 to 24%.

Abstract A study has been conducted for 3 consecutive years since 2019 to 2021 to investigate the influence of cultivation system of Arabica coffee against the attack of the coffee berry borer (Hypothenemus hampei Ferr.) in Arabica coffee plantations in Aceh Tengah District, Aceh Province, Indonesia. We observed the attack level of H. hampei on Arabica coffee plants that were cultivated both organically and conventionally. The results showed that for three years observation, in general, the attack level of coffee berry borer (CBB) on organic and conventional coffee plantations was not significantly different. Observations in 2019 showed that the attack level of CBB on organic coffee plantations ranged from 27-34 % and on conventional coffee plantations ranging from 33-49 %. Observations in 2020 showed that the attack rate of CBB on organic and conventional coffee ranged from 20-40 % and 28-41%, respectively, while observations in 2021 were 25-26 % and 27-28 %. The results of these studies indicate that the level of CBB attack on organic coffee plantations is no different from conventional coffee plantations that routinely use synthetic pesticides. This indicates that in organic coffee plantations, natural enemies have played an important role in suppressing the development of CBB populations. Although the use of synthetic pesticides in conventional coffee plantations can suppress pest populations, it is suspected that these pesticides also play a role in reducing the population of natural enemies of pests. Therefore, organic coffee cultivation is much more profitable, especially it can reduce the cost of buying synthetic pesticides and fertilizers, besides ensuring the safety of coffee farmers, workers, and consumers from harmful chemical contamination from pesticides.

Starting Point

Coffee berry borer (CBB, Hypothenemus hampei Ferrari) is the most serious insect pest of coffee worldwide, yet little is known about the effect that weather variables have on CBB flight activity. We sampled flying female CBB adults bi-weekly over a three-year period using red funnel traps baited with an alcohol lure at 14 commercial coffee farms on Hawaii Island to characterize seasonal phenology and the relationship between flight activity and five weather variables. We captured almost 5 million scolytid beetles during the sampling period, with 81–93% of the trap catch comprised of CBB. Of the captured non-target beetles, the majority were tropical nut borer, black twig borer and a species of Cryphalus. Two major flight events were consistent across all three years: an initial emergence from January-April that coincided with early fruit development and a second flight during the harvest season from September-December. A generalized additive mixed model (GAMM) revealed that mean daily air temperature had a highly significant positive correlation with CBB flight; most flight events occurred between 20–26°C. Mean daily solar radiation also had a significant positive relationship with flight. Flight was positively correlated with maximum daily relative humidity at values below ~94%, and cumulative rainfall up to 100 mm; flight was also positively correlated with maximum daily wind speeds up to ~2.5 m/s, after which activity declined. Our findings provide important insight into CBB flight patterns across a highly variable landscape and can serve as a starting point for the development of flight prediction models.

Flowering weeds can serve as refugia for natural enemies. In coffee plantation, they might has the potential to attract predator and parasitoid of Coffee Berry Borer (CBB), Hypothenemus hampei Ferr. (Coleoptera: Scolytidae). The aim of this research was to elucidate the influence of weeds to the presence of predator dan parasitoid and their impact to the population of CBB. The research was conducted at Ngantang, Malang Regency and in Laboratory of Pest, Faculty of Agriculture, Brawijaya University. Three types of weed used were: Ageratum conyzoides L. (Asteraceae), Synedrela nodiflora(L.) Gaertn. (Asteraceae), and Arachis pintoi Krap. & Greg. (Fabaceae). The research consisted of two experiments (1) coffee plot with single species of weed and (2) coffee plot with two species of weeds. The results of experiment I and II showed that A. conyzoides, S. nodiflora, A. pintoi and its combination in coffee plantation significantly attracted the predator and parasitoid of CBB. The population of CBB was not significantly different between coffee plot with and without weed. The existence of A. conyzoides, S. nodiflora and A. pintoi in coffee plantations could increase the number of predator and parasitoid of CBB around coffee tree. This result showed that the presence of weeds in coffee plantation is an important factor in maintaining the predators and parasitoid of CBB population.

The coffee berry borer, Hypothenemus hampei, is serious limitation in organic coffee production in Sao Tome Island in the Gulf of Guinea, limited information regarding this species seasonal phenology on the islands limits the implementation of biological control.In the present study, seven coffee plantations were monitored over two years to describe infestation patterns, penetration rates into coffee berries, and mortality by the entomopathogenic fungus,Beauveria bassiana in two coffea species (C. arabica L.and C. canephoraPierre ex A. Froehner), according to 30-tree sampling of fruits following the CENICAFE method. The results revealed that the borer position within the berries, infestation, and green berries with Beauveria bassianawere significantly affected by coffee variety. The infestation mean across all seven sites was (11.5±3.5% mean ± standard error (SE)), with two sites showing mean infestation <5%. The highest infestation and Beauveria bassianarates per branch monthly were observed in C. arabica L. (Red Caturra, Bourbon and Red Catuai), compared with C. canephoraPierre ex A. Froehner (Robusta) in the months of lower rainfall. Borer immature stages (eggs, larvae and pupae) and adults were found throughout the sampling period. No CBB predator and parasitoids were observed in the survey. The population level and developmental rate indicated that the coffee borer met favorable environmental conditions in the studied areas and control measures are required for reducing damage.
